Historical maps
(screenshots or sketches up here)
The group discussed the usage of historical maps and geodata using the Wikimedia environment. Out of the discussion we decided to work on 4 learning items and one small hack.
The learning items are:
- The workflow for historical maps - the Wikimaps workflow
- Wikidata 101
- Public artworks database in Sweden - using Wikidata for storing the data
- Mapping maps metadata to Wikidata: Transitioning from the map template to storing map metadata in Wikidata. Sum of all maps?
The small hack is:
- Creating a 3D gaming environment in Cities Skylines based on data from a historical map.
Data
- Example data from a previous hack…
The Small Hack - Results
Our goal has been to recreate the historical area of Helsinki in a modern game engine provided by Cities: Skylines (Developer: Colossal Order). This game provides a built-in map editor which is able to read heightmaps (DEM) to rearrange the terrain according to it. Though there are some limits to it: The heightmap has to have an exact size of 1081x1081px in order to be able to be translated to the game's terrain.
To integrate streets and railways into the landscape, we tried to use an already existing modification for Cities: Skylines which can be found in the Steam Workshop: Cimtographer by emf. Given the coordinates of the bounding box for the terrain, it is supposed to read out the geometrical information of OpenStreetMap. Unfortunately, the algorithm is not working that properly - though we were able to create and document some amazing “street art”.
