Wikimaps Warper 2.0

Tim Waters, Susanna Ånäs, Albin Larsson and Ari Häyrinen received an IEG (Individual Engagement Grant) from the Wikimedia Foundation to work on a renewed Warper for the Wikimaps project.

We have observed that if the Warper experience was easier and more pleasant, we would attract more volunteers in warping old maps.

In order to let some developers work on the program features and others on the user interface, we would need to separate program components, decouple them. The program could serve any external application through the API. The Warper’s own user interface would be one of the program’s clients, and the Warper program would be dogfooding the Warper interface.

New features

We also have neat new features that we had already started to work on. Stay tuned for specific blog posts about them!

  • Importing a Commons category of maps to the Warper.
  • Importing control points for already georeferenced maps for single maps as well as batches
  • The most wanted from the feature wish list


We are focusing only on the program features in this project, but we are guided by the envisioned design of the tool. Have a look and comment the evolving mockup doc.

What we put in, who we address, what comes out in short, medium and long range. Do you agree? Have a look and comment!

What to expect

We will arrange focused meetings with advisors regarding specific aspects of the development, and make documentation about the meetings available. Additionally, there will be a public Hangout session open for everyone. If you wish to participate, enroll as volunteer or leave a note on the project page.

About us

Tim Waters – back end. Tim is the original developer of the MapWarper software. It was originally created for the New York Public Library, where it serves thousands of openly available maps. The open source code has spawned MapWarpers around the globe.

Albin Larsson – front end. Albin has worked on the iD editor for OpenHistoricalMap, a sister project for the Wikimaps project. He has made a proposal for a linked data approach to OpenHistoricalMap data and created a prototype of modeling historical buildings in 3D.

Ari Häyrinen – integrations. Ari is developing a metadata enhancement tool to be used with GLAM mass uploads in a Wikimedia Finland project. The project will link between copies of files in different repositories to take advantage of spatial mapping possibilities offered by some of them.

Susanna Ånäs – coordination, design. Susanna has run the Wikimaps project and network over a two-year period. She will contribute to the design aspects, but mainly her task is to facilitate communication and participation in the project.

The Documentation page in the Wiki Loves Maps site will be updated with new posts.

We appreciate if you fill in the survey. It’ll help justify further events in the future! If you can’t find the email, use this link! Thank you!


Historical Aleksanterinkatu

The theme of Wiki Loves Maps was Historical Aleksanterinkatu. It’s a joint initiative with the City of Helsinki to gather historical materials about the city, combine and reuse them. Arend Oudman gave a bird’s eye view to the city through the series of Historical aerial images from the Metropolitan area he has gathered, prepared and opened. Martti Helminen from the City Archives is the originator of the Aleksanterinkatu theme. He took us through the history of the street with images, maps and drawings.

DIY History

We collected a set of speakers to present different approaches to working with local and personal history. These materials have fallen outside publicly funded GLAM endeavours, they are not suited for Wikimedia for their lack of notability and they largely live in commercial services.

#Hack4FI hackathon

The hackathon, the first of a kind in Finland, was a tour de force of AvoinGLAM. After the weekend participants have six weeks to finalise their works. The hackathon ends 26 March with a gala, where the final works will be presented and awarded.

Wiki Loves Maps projects were only a part of hacks done over the weekend, and you can see a full list of ideas here. Have a taste of maps projects, or projects by mappers, that were worked on during the event!

Historical street view


We aim to connect two projects: Ajapaik for using people’s help in locating places of old images and Mapillary for seamlessly stitching those images into a street view. Signe Brander’s Helsinki images are in Ajapaik already and more will follow! The first test transfers from Ajapaik to Mapillary are being made.

OpenStreetMap – OpenHistoricalMap – (Wikimaps) Warper

Map of OpenStreetMap objects with links to Wikipedia articles

See shapes of buildings and monuments that have Wikipedia articles on a map. Themap background can also be a historical map. By Tuukka Hastrup @tuukkah.

If the background map needs adjusting, go to Wikimaps Warper to fix it! If the link to a Wikipedia article is missing, add Wikidata/Wikipedia tags to objects in OpenStreetMap. If a Wikipedia article is missing, you should write one! (And translate it to several languages.)

Helsinki streets of 1900 in OpenHistoricalMap

You can only store today’s features in OpenStreetMap. This is where OpenHistoricalMap comes in. See OpenHistoricalMap at work inside the Wikimaps Warper. The streets have been stripped from the present-day OSM map based on a scanned map of 1900. You can continue the work, adding, deleting and modifying!

Guests from afar

Ecuadorian Paul Villavicencio studies Information Science in Nagoya, Japan. The words Galleries, Libraries, Archives and Museums caught his attention on the Wiki Loves Maps web pages and he decided to travel to the seminar and take part in the hackathon.

While studying in Ecuador, Paul worked in the university library. The librarian, his friend and colleague, is an advocate of openness and collaboration with memory institutions. The possibility of contributing to his work made Paul choose to join the event.

#Hack4Fi was Paul’s first ever hackathon and he was not sure what to expect. After a bit of disorientation facilitator Sanna helped him join a project team and use his expertise on content retrieval in the Talking Heads project. Seeing memory institutions take part in hacking among others, and participating in cross-disciplinary work was a memorable experience. What made all this worthwhile, is that he hopes to bring back his experiences to his colleague in Ecuador.

We talked with Paul together with Mace Ojala, an information science student and participant in #Hack4FI

Looking forward to the next cultural hackathon. Hope to see you all there!

We are here. Where do we go next?


Wikimaps participated in 3 different international events in November. This was the time to look back to where we have got to and what kind of opportunities the work has opened.

Creating a maker space for location-­based historical storytelling

Bringing Historical Geodata to the Web
New York Public Library, November 5–7

Wikimaps has become part of an ecosystem of initiatives that aim to open and understand the geospatial cultural heritage captured in the documents held in libraries, archives and museums. We were especially happy to be invited to the event Moving Historical Geodata to the Web organized by New York Public Library. The event gathered together actors from the academia, open source and civil sectors from 3 continents to tackle the flow of historical geodata from printed maps to finally making use of it in cultural applications. The goal was to see where projects overlap, and think of common ways to deal with redundancy.

Common ground was sought after with different exercises during two intensive workshop days. In the end of the days, the participants committed to some common goals.

The Wikimaps project commits

to contribute to the OpenHistoricalMap project as a project companion and establish a seamless workflow from old maps to OpenHistoricalMap. The communities are planning future working methods, and we hope to share some of the tasks together.

Another key element of the Wikimaps roadmap has been to be able to use Wikidata as a gazetteer, a database that can connect place names and geographies and their changes through history and across languages. Humphrey Southall, University of Portsmouth, nominated as Educational Institution of the Year in Wikimania this year, has done pioneering work with testing this in practice with the PastPlace gazetteer. The Pelagios project and others have been investigating the idea of the Spinal gazetteer, a gazetteer that is a reference gazetteer for individual gazetteers created in various research projects and initiatives.

In order for Wikidata to serve as a historical gazetteer we must see that

  • the way places and place names are modelled serve historical gazetteers: the alternative names of places can be limited to date ranges or to a specific context.
  • the granularity of places accepted in Wikidata will serve at least gazetteers (towns, villages, hamlets, neighborhoods as well as rivers, islands, lakes etc.) if not even more detailed geographic entities.
  • all geographic elements on maps would be notable enough to be accepted in Wikidata.
  • there will be a good way to include or link to the historical geographic representation.

While waiting for the collected input of the workshop, you can have a look at the slide deck of the participants’ presentations, the participant bios and Lex Berman’s notes for the event. We also shared our experiences about building the Wikimaps community, which appear on separate slides here.

Wikimaps Expedition

State of the Map, Buenos Aires, November 7–9

State of the Map, the yearly congregation of the OpenStreetMap world, was organized for the first time ever in Latin America. Wikimaps was presenting the idea of the Wikimaps Expedition. The project model will try to fuse practices from the successful GLAM projects into the participatory mapping projects as well as the meaningful humanitarian approaches.


Initially thought to be arranged in the Archipelago Sea, in a bilingual area between Finland and Sweden, the expedition would take many forms. The project would engage GLAMs, experts, wikimedians, mappers and locals in a common effort to research the story of a location.

The work would have a preliminary online phase, during which historical maps, photographs and geodata are uploaded to Wikimedia Commons with the help of volunteers and experts. Wikipedians would edit articles and create new ones on the area. Mappers would do historical mapping and upload historical geodata sets to OpenHistoricalMap.

Locals and project participants would get together on location during the preliminary phase through field trips and other meetings, and finally an expedition would take place: collection events, interviews, editathons, mapping parties and workshops, staying together producing and documenting with all different project participants and partners on location for perhaps a week.

Amazing participation

The highlight of the event was the presentation by the schoolchildren of the Río Chico. Their education is entirely carried out over the web, as there is no local educational staff. They have mapped their little village and had travelled to the event to present the project. I missed it on location, but was able to catch up on video.

Wikipedia TOWN

The guidelines for notability and prohibition of conducting original research in Wikipedia have led to the situation that the enormous energy of people doing research on historical personalities and locations cannot be tapped into.

I familiarized with the Japanese project Wikipedia TOWN, that has also set out to tackle these problems. They contribute to 3 different repositories: OpenStreetMap, Wikipedia for notable topics, and LocalWiki for topics that don’t meet the criteria of Wikipedia.

The Spatial in Digital Humanities

A week of Digital Humanities in Lausanne with DH2014 was packed with projects sorting out and displaying cultural heritage. The emphasis is more on the ’sorting out’, as Digital Humanities is an academic discipline. It has a strong emphasis of textual analysis in English language, but there is more to it.

Susanna Ånäs presented Wikimaps with a position paper and a presentation in the inaugural meeting of the GeoHumanities special interest group, a group gathering knowledge on the spatial research of cultural heritage.

Gazetteers and the GeoHumanities SIG

The first one of the initiators of the SIG, Kathy Weimer (Texas A&M University) opened the series of presentations about gazetteers with Geographic name authority records in the Map & GIS Library. Gazetteers are place name dictionaries, as described in Wikipedia. This meeting was another step to make the gazetteers of different research projects communicate with one another.


The academics working with gazetteers have largely congregated around the Pelagios 3 project. Elton Barker (Open University), Leif Isaksen (University of Portsmouth) and Rainer Simon (Austrian Institute of Technology) are carrying out the principle: “Don’t unify the model – annotate”, allowing gazetteers to link to one another without completely remaking them. A new outcome is the Recogito text annotation tool to identify and link place names.
Paper: Pelagios 3: Towards the semi-automatic annotation of toponyms in early geospatial documents

Stuart Dunn (King’s College London) presented The Heritage Gazetteer of Cyprus. It gathers place names in Cyprus from different sources into a gazetteer. Modern place names are combined with historical units and archaeological entities. The project deals with layers of challenges: different transliterations and varying ideological perspectives. In the project one place name will not be preferred over another as a default name. Another strength of the project is a rich and thick description of places names of a limited location.
Blog: Heritage Gazetteer of Cyprus: evolving thinking

Miranda Anderson and Beatrice Alex (University of Edinburg) showed the Palimpsest project that geo-locates extracts of literary works of Edinburg from the early modern period to the twentieth century. The Edinburgh Geoparser is used to georeference fine-grained place names in the texts: streets, buildings, local areas, and vernacular terms such as “Old Town.” The project tools and outcomes will be openly accessible, and imaginative events will engage participants interested in the local heritage.

banner-omo-web-232x90Petr Pridal (KlokanTech) described the Old Maps Online service. It is an aggregator of old maps, and it displays a collection of 150 000 old maps from archives around the world. The number will rise to 450 000 with a forthcoming update. Future directions include even stronger support for touch devices, transcription tools for place names and support for linked data formats, such as JSON-LD. Search engine optimization for old maps is a great idea: Typing ”old maps of Lausanne” the Google search will find the maps directly. New features for georeferencing maps are being added to the Georeferencer tool that accompanies Old Maps Online. Using OpenHistoricalMap for vectorizing old maps is also being considered.

Humphrey Southall (University of Southampton) presented one of the Pelagios 3 network projects, the PastPlace. In GIS gazetteers have been seen simply as lists of geographical names and coordinates. In the past gazetteers were far richer: place encyclopedias, describing localities and their relationships with other geographical entities. PastPlace has set out to prove the use of Wikidata as a gazetteer. It includes places from Vision of Britain Through Time. Only those that have a Wikidata entry are included. The aim is to make entries for the missing ones.

Karl Grossner (Stanford University) has worked extensively on Topotime together with his colleague Elijah Meeks (Stanford University). Contrary to representing time with ISO-8061 standard dates for start and end dates, the proposal sets out to express more uncertain dates like: “for 6 months before the war,” “around 1832,” or “during harvest seasons in her youth”. The project produces a specification for representing temporal entities typically found in historical texts, and some relationships between them. The authors have created graphical timeline layout programs to parse and render Topotime data and software tools to create Topotime data from excels and whatever the researchers happen to have.
Paper: Topotime: Representing historical temporality

Eric Kansa (OpenContext), Adam Rabinowitz (University of Texas at Austinand Ryan Shaw (University of North Carolina at Chapel Hill) introduced us to the Period-O project. The project creates a gazetteer of periods in history, art history, and archaeology. Instead of aiming at consensus about national and scholarly boundaries about the spatial and temporal coordinates of specific period concepts, the project proposes the construction of a Linked Data gazetteer of authoritative claims about the spatio-temporal coordinates of periods.

Asanobu Kitamoto (National Institute of Informatics, Japan) and Yoko Nishimura (Toyo Bunko / JSPS Research Fellow) have worked on The Digital Silk Road project. It tries to make sense of incorrectly recorded geographical data by comparing several sources together. Locations are unfolded one by one, looking at local constraints, without trying to serve the overall co-existence of items on the map. Mappinning is an interactive tool that lets the user view the map with and without the transformation alternatively.

Venice Time Machine

A morphing video of Venetian Cartography in The Venice Atlas project of students of EPFL DH101

The host organization EPFL is the home of the Venice Time Machine project. The project has set out to digitize the 80 km of documents in the Archivio di Stato of Venice: birth and death registries, architectural and urban plans, maps, travel guides, treaties etc. There are a hundred scholars working on the project’s different aspects. Apart from re-creating social networks and family trees, novel challenges are tackled. Handwritten manuscripts are automatically read using new algorithms. Scanning a book without turning it’s pages may be possible using a particle accelerator. Frédéric Kaplan, the innovative director of the project, called for Google Maps of the past in his popular TED talk: Can I add a slider on top of Google Maps and just change the year, seeing how it was 100 years before, 1,000 years before?”

Spatial and temporal

Bethany Nowviskie‘s keynote Digital Humanities in the Anthropocene was presented by Melissa Terras, as Bethany was unable to be present. The dark-toned keynote painted a picture of the humankind at the brink of ecological destruction, and discussed time, preservation, degradation and loss.

Bethany Nowviskie runs the Scholar’s Lab at the University of Virginia Library, that have produced tools for digital humanists. Neatline is a map storymaking tool for hand-crafted, interactive stories of a single document or a whole archival or cultural heritage collection. It builds on another open source tool, the Omeka, a web-publishing platform for both GLAM and hobbyist archival projects.

The other keynotes were given by Bruno Latour (Sciences Po), Ray Siemens (University of Victoria) and Sukanta Chaudhuri (Jadavpur University).

Stories with maps

Näyttökuva 2014-7-17 kello 18.33.30

Interface of the Campus Medius Topography

Simon Ganahl (Department for German Studies, University of Vienna), Rory Solomon (The New School for Design, New York) together with Mallory Brennan and Darius Daftary have produced the Campus Medius project. It is a study of Turks Deliverance Celebrations held by the Austrian National Socialists and the Home Guards during twenty-four hours in Vienna between May 13 and 14, 1933. The creators use the concept of chronotope, a bakhtian literary concept of space-time, defining the intrinsic connectedness of temporal and spatial relationships”.

The artistic research has resulted in an interactive map and an interactive documentary. The Topography – the interactive map – uses Urban Research Tool (URT) for geospatial mapping, developed at Parsons The New School for Design. The Topology – the interactive documentary – exists within Zeega, a tool for interactive storytelling developed at Harvard’s Sensory Ethnography Lab. The project will be published open-access in the online journal Sensate in 2014.

Lauren Tilton and Peter Leonard (Yale University) and Taylor Arnold are the creators of Photogrammar, a project showing and locating images of the the Farm Security Administration – Office of War project on both current and historic maps.

The collection of over 170,000 monochrome and colour photographs were commissioned between 1935 and 1945 by the government of the United States of America. It also includes several of the most iconic images of the 20th century, such as the Migrant Mother of Dorothea Lange. The photographic archive has been digitized by United States Library of Congress, and because the photographs were taken on behalf of the United States Government, access to and use of the collection is essentially free and open.

Several methods were used to analyze and visualize the images. The geospatial study shows that the scope of sight was much broader than the American south. Text Mining reveals thematic similarity between the work of several different photographers. Statistical Analysis using contextual inference lets the researchers “rediscover” missing metadata, placing detached negatives in their original context.

Paper: Photogrammar: Organizing Visual Culture through Geography, Text Mining, and Statistical Analysis


Jim McGrath and Alicia Peaker (Northeastern University) presented a poster about the Boston Bombing Digital Archive. It showcased the use of Omeka and Neatline. Stories, maps, photographs, social media logs and oral histories were collected in an endeavour that connected many different actors: universities, libraries and media companies in Boston in the aftermath of the bombing. The work was inspired by similar projects, such as The September 11 Digital Archive and The Hurricane Digital Memory Bank.

Maps at the Zürich hackathon

The Wikimedia Hackathon was held in Zürich this year with a focus on maps. As a conclusion, it seems maps will be an integral part of what Wikimedia is, as soon as everything presented is taken into use.

Erik Möller (Wikimedia Foundation) envisions that will be a new project, with a community and repository of it’s own. The space could host tools for creating maps as well as geographic data in all it’s forms.

The Maps namespace

Jon Robson (WMF Engineering, web), Katie Filbert (WMDE, Wikidata) and Derk-Jan Hartman created a MediaWiki extension for maps. It introduces a Map namespace where data for the map is stored in raw GeoJSON and can be edited via a JavaScript map editor interface. It also allows the inclusion of maps in wiki articles via a template.

Näyttökuva 2014-5-19 kello 8.26.23The demo:
The codebase:

Wikimedia tiles

Having Wikimedia’s own tileserver has finally moved forward. Kai Krueger, Tim Alder and Alexandros Kosiaris (WMF, Engineering, operations) have worked to set up a test environment, that shows the base map in several languages. The styles priority list is currently: Mapnik-default, -nolabels, hikebike, black&white, WikiMiniAtlas, multilingual map and hillshading.

Vector rendering is high on the wish list. It would be ideal for historical maps, as there is an infinite number of snapshots of history which should be rendered as tiles. I would not like to be the one who curates important dates!


Our project Wikimaps might need a new name. When we move under a umbrella, we become the Old maps project, the OpenHistoricalMap counterpart in the Wikiworld and the Wikimaps Gazetteer project.

Using the Maps namespace for old maps

In our Old Wikimaps project a key use case for the new Maps extension is the display of the old map layered on top of the current map. It can be used on the map file page on Commons or in the upload wizard, with an interface for positioning the old map on the current map. In this example, the interface is a collection of items from the iD editor for OSM, the Maptcha project and the Wikimedia styles.

Template:Map for map metadata

André Costa (WMSE) worked to finish the first version of the Template:Map, that we want to include in the GWToolset as well as the Upload Wizard. We are still open to influences: Please give feedback! Wikidata will soon take over handling Wikimedia Commons metadata, and these metadata templates will become obsolete. But in the meanwhile, we will upload hundreds of maps with their help and learn about maps metadata.

The information has different layers:

  1. Image data that is similar to data about any image.
  2. Publication and copyright: the cartographer, publisher, printer etc.
  3. Geographic: point or bounding box, place names, time, scale etc.
  4. Object in the archive: materials used, ID, institution data etc.

Bridging between projects

A wealth of maps projects were presented:

Beat Esterman (WMCH) rectified old Zürich maps and provided us with a lot of valuable user testing with the Warper.

Simone Cortesi (WMIT) also had a set of Italian maps to rectify.


Petr Pridal from Klokantech produces a georeferencing environment that is used by many memory institutions and the map portal OldMapsOnline. Jakub Kaniewsky has produced Sharemap, a toolset for working with maps, that also features map rectification. We discussed the interoperability of data produced in these environments.

Tim Alder has created a map view for showing items in specific classes in Wikidata. See the tool in:

The Reasonator is a creation by Magnus Manske, an original creator of MediaWiki. It is an environment to test Wikidata capabilities that are not yet in production. The latest addition to the toolpack has been the display of Wikidata items within a certain radius from a point on the map. You can follow the new features in Reasonator and Wikidata in Gerard Meijssen’s blog Words and What Not.

Collaboration between Wikimedia and OpenStreetMap

Simon Poole, the chair of OpenStreetMap Foundation attended the hackathon, and lead a group of people on a tour around Zürich. It was a mapping party: We collected house numbers by sneaking around houses, marked forgotten details and corrected errors made by ignorant German mappers!

There were many pressing topics to be discussed between OSM and Wikimedia, and the presence of the new ED of the Wikimedia Foundation Lila Tretikov made the event feel like the Davos of open knowledge.

The most important issue is to solve the incompatibility in licensing between the Wikimedia and the OpenStreetMap projects. Even if it is possible to combine the projects through skillful linking, it is not easy for a volunteer to navigate the differences. We are excited to see the enthusiasm in both projects to create something great together and wait to see what the legal teams in the organizations will come up with.

Tracking crossover projects

Quim Gil (WMF, Engineering community) has created a page to collect crossover projects between Wikimedia and OpenStreetMap. A Wikimedia Tech Talk around maps is also planned.

More maps, different maps

Using OSM data on a map in Wikipedia is only one of the many use cases that are out there. We also have the OpenHistoricalMap database to map to Wikimedia data. Through weighing several options, we promote the solution where the OHM database is kept separate from Wikidata, and items are mapped against each other only when needed. Geographic contributions are made to the OHM database and further content in Wikidata. If this sounds obscure, let’s discuss more in the RfC!!

Tim Alder outlined a new proposal to store “ephemeral geodata” in an instance of the OSM toolstack, the Open-Wikidata-map. This means fuzzy features such as climate regions, habitats of animals and thematic features of all kinds. Mikel Maron has proposed such infrastructure in a recent talk in SotMUS OpenStreetMap as Infrastructure.

The OpenSeaMap is another specialized geo database, that could be linked across to Wikipedia articles about seas, rivers, water sports and shipping affairs.

More proposals

Tim Alder also proposed to initiate a network of local OSM/Wikimedia ambassadors in as many countries as possible. They could create projects and organize events, and work in collaboration with the forthcoming Maps & Geo Team at Wikimedia Foundation.

The authentication across projects through OAuth should be put into action.

Simon Poole mentioned the idea to collect aerial imagery, both user-generated and open data. Tim Alder reminded it would be a natural continuation after WMDE’s support for OpenGeoServer.

Andy Mabbett suggested the use of crowdsourcing games and bots for adding Wikipedia links to OpenStreetMap objects.

Going beyond maps

Dan Andreescu (WMF Analytics) worked on a visualization framework that overlaps a bit with the Maps namespace. Have a look at the famous Napoleon flow map by Charles Joseph Minard created by the extension!

Discussion page about open datasets

Open data worldsThe event gathered many open data activists, and there were many discussions about how and where to store open data within the Wikimedia family. David Cuenca created a page to answer (or – in fact – ask) some of those questions.

Wikimaps Nordic kickoff

It was a great start for a journey into the maps and places of the 5 countries: Finland, Sweden, Norway, Denmark and Estonia. The kickoff event had gathered representatives from all of the countries.

The support from the Nordic Culture Fund shows the willingness that there is to make cultural heritage widely digitally available in the participatory Commons. The Finnish Institute in London also showed continuing interest in activities of open culture, following the participation in the Open Knowledge Festival in Helsinki in 2012.

The presentations

Our speaker guests showed examples of what can be done with maps, data and wikimedians:

Laurence Penney presents one of his strip-map tresure, the Tabula Peutingeriana before and after MapWarper.

Tim Waters (UK), the creator of the MapWarper for New York Public Library, showed the many projects which the MapWarper has made possible. From rectifying maps for disaster relief mapping to making possible to trace the contours of New York buildings. The Wikimaps Warper has already been set up to work with the maps in Wikimedia Commons, and work will continue with more integration and interface design.

Old GLAMs meeting young Wikimedia. Which one is which?

Old GLAMs meeting young Wikimedia. Which one is which?

Hay Kranen (NL) reported about his experiences and thoughts as the first Dutch wikimedian-in-residence, working in the KB Library and National Archives in the Netherlands. He cited a research that showed that the most used information source is Wikipedia for 52% of the Dutch population, but the books and libraries are primary to only 1%! It makes sense to try to make available the riches of the libraries and archives in the world’s most visited encyclopedia.

Nordic wikimedians (Jan Ainali and André Costa from Sweden, Jon Harald Søby from Norway, Henrik Sørensen and Michael Andersen from Denmark and Vahur Puik and Raul Veede from Estonia) reported the work we have been preparing with the GLAMs in the partnering countries. We are expecting both volunteer projects and activities with many GLAM institutions.

We then had interesting presentations from our Finnish network:


Istvan Kecskemeti from the National Archives of Finland outlined how the treasures of the archive are unreachable without proper search mechanisms put into place and envisioned better services to find the materials. He also presented a browsing interface done by Leslie Kadish for the Senate Map collection.

Helsinki 1956 / Land Survey of FinlandHeli Laaksonen from the National Land Survey described their digitization project with historical aerial images. They, too, are unreferenced, and therefore cannot be searched and found.


Tomi Kauppinen from Aalto University showed SAPO, the Finnish spatiotemporal ontology, and the work that remains to be done to get full coverage of historical administrative borders. The National Linked Data Gazetteer of Historical Places project was announced a day earlier.

Helsinki ilmakuvina 1943–2012

Arend Oudman and Outi Hermans from the City of Helsinki showed how they have opened and processed maps and aerial images in the context of broader efforts by the City of Helsinki to work with open data. The image shows the Historical Aerial Images browser.

The workshop

After hearing the introductions, we focused on a set of themes during the afternoon workshop:

  • MapWarper & iD development & map search
    Developing the tools to be easier to use while maintaining complexity. We are creating a toolset to communicate with both Wikimedia Commons and Open Historical Map. The key features will be search, warping and vectorizing, with a seamless user experience switching between the tasks. We are starting a structured work process for development.
  • The Pan-Nordic map project
    We found out that instead of a unique map covering all Nordic countries we will get interesting insight by looking into individual areas, especially cities. Focusing on places on a human scale will allow narrating with more materials, such as images. The work will be administered by chapters.
    If you are interested in participating, please be in contact with the Wikimedia chapter in your country.
  • Aerial images case study
    Together with the Aerial Images archives at the Land Survey of Finland and other participants we will select a suitable set of material for a case study. We will research different workflows and look at open tools to use with aerial images. It will make sense to support the Nordic map project with the aerial images.
  • Gazetteer
    We will further collaboration with place name projects, such as Pelagios 3 and the National Linked Data Gazetteer of Historical Places (SeCo), and work actively in the creation of place attributes in Wikidata. The Swedish volunteer project gathers municipality border data for a practical demonstration. We may develop mechanisms for allowing volunteer participation in gathering and interpreting the place names together with the Finnish gazetteer service. Susanna and Tomi Kauppinen have been included in a workshop proposal by the GeoHumanities SIG for a workshop Place and Period in an Emerging Global Gazetteer: a proposed DH2014 workshop.

Additionally we will be working with at least the following topics:

  • Wiki Loves maps – the hackathon
    A hackathon event is being planned for the Autumn. An idea about informal hacking events more regularly was presented.
  • Maps in Wikimedia Commons
    This development will include work to define map metadata for storing maps in Wikimedia, applying that to the map template and the GWToolset.

Wikimaps online meetings start to roll in the New Year

The Wikimaps project will kick off at the New Year.  We are meeting in two creative communities:

The  Designers & Developers

Everyone, who is interested in developing the tools and the content for the Wikimaps: wikimedians, openstreetmappers, glammers and others.

The Wikimaps Nordic

Wikimedia chapters, OpenStreetMappers and GLAMs from Finland, Sweden, Norway, Estonia and Denmark.

Wikimaps around the World

The Wikimaps project was involved in a chain of international events. First in series was State of the Map Baltics organized in Tartu, Estonia. The series continued to Wikimania in Hong Kong ja finally the project was part of a code sprint organized to celebrate the 9th birthday of OpenStreetMap.

In Tartu

Together with the Baltic mappers we arranged a workshop on historical maps of Tartu. The Estonian National Archives, the National Library and Tartu University provided us with the old maps. They depict the city of Tartu over the years 1892–1986. All maps used in the workshop are now available in hi-res in Wikimedia Commons.

Pharus-Plan Dorpat, 1910

Pharus-Plan Dorpat, 1910

Tartu’s history is multifaceted: The fortress, that was known as Tarbatu in the first centuries AD, was renamed Yuryev when Yaroslav the Wise, the Grand Prince of Kiev renamed it after his Christian name Yuri. Conquerors and names kept changing since. In the end of the 13th century Tartu was a member of the Hanseatic League under the name Dorpat. For the Swedish rulers Tartu was known as Dorpat, as well as for the Polish ones. The Estonian name Tartu was adopted since Estonia detached from Russia in 1918. This was good material for our workshop.

OpenStreetMap actives from Estonia, Finland, Russia, Belarus and Poland were gathered in the main building of the Tartu University. OpenStreetMap Foundation representatives from western Europe attended also.

We started the workshop early Sunday morning. I presented the maps and the challenges

  • Who would use old maps?
  • How could the historical maps be used?
  • Comments on a specific section of the Wikimaps plan

We worked with a tight schedule in five groups. Attentive sounds of discussion filled the space. Two of the groups managed to get their thoughts on paper.

The first group discussed the properties that are to be collected from a map. As an example, when a mapper traces the Tartu Town Hall, there is no way of knowing the start_date, the construction year of the building – only that it existed at the given date. Or maybe the map is not truthful. In one of the maps from the Soviet era the geographic features had been falsified.

Jogging track from old railway line. What happens to travel times?

We discussed routing and calculating travel times along historical itineraries. Routes emerge and disappear: bridges are bombed, railway tracks removed and a cycling track is built in place, new highways are built.

The proposal for mapping Paris of the Musketeers triggered more ideas of placing literature on a map: Pubs of Joyce’s Ulysses, Sherlock Holmes’ London, Robin Hood in Nottingham and mapping the land of Kalevala, the national epic of Finland. Biographies of historical figures could be placed on a map in Wikipedia.

In Hong Kong

Later the same week hundreds of wikipedians gathered in Hong Kong for Wikimania from all over the world. During the event the participants in the multitude of Wikimedia projects can exchange experiences and tighten their collaboration. On the other hand it is an opportunity for the Wikimedia Foundation staff to discuss developing the environment together with the volunteers. For Wikimaps it was an chance to show what we have done and start establishing the project.

Round table discussion

The first thing done in Hong Kong was organizing a round table discussion about geodata in Wikimedia. Particiapants were people from Wikimedia projects that use geodata as well as people from the Wikimedia Foundation.

  • Maarten Dammers presented the Geographicus map donation he has helped to upload in the Commons.
  • Barbara Fischer presented a work in progress for a time-based animated map of Römisches Limes representing the erection and disappearance of Roman fortresses in Central Europe. The German Wikimedia organized an interesting event Wikidata trifft Archäologie 2013 this spring that gathered together the people working with definitions of place in the Ancient world.
  • Hugo Lopez is starting a project where maps for Wikipedia articles could be created from GIS data dynamically.
  • Daniel Kinzler explained the state of geodata in Wikidata.
  • Wikimaps presented briefly.
  • Tim Alder ja Daniel Schwen were present. They have been creating connections between Wikimedia and OpenStreetMap over the years. WikiMiniAtlas, OSM-Gadget, Geohack and WIWOSM have been made by them.

We discussed the needs of the projects and created a document.


By the end of the week Susanna presented Wikimaps together with Maarten Dammers. Maarten is a volunteer of great projects in the Wikimedia Commons and he has originally proposed a project by the name Wikimaps.

Wikimaps Warper työssä

Wikimaps Warper at work

We presented the Wikimaps Warper that has been customized for Wikimedia Commons by it’s original developer Tim Waters. It is now possible to georeference images in the Wikimedia Commons. The maps that have been georeferenced, can in turn be used in Open Historical Map for mapping historical features with OpenStreetMap tools.

OpenStreetMap Birthday Sprint

With all we had done and presented over the course of the week, we were part of the OpenStreetMap code sprint. 12 hour time zone difference made it impossible for us to do things together, simultaneously. The maps of Tartu had travelled from archives in Tartu via Hong Kong to an event in the US.
