As a combination of bachelor project / bachelor thesis.
A basic way to create schematic transit maps is to iteratively replace existing straight arcs between stations by circular arcs. Possible results can be seen in this poster presentation by van Dijk et al.: http://www1.informatik.uni-wuerzburg.de/fileadmin/10030100/_temp_/circularArcMetro_01.pdf
Goal: Reproduce the results shown in this presentation. We already have a tool available to render the maps. Your work would mainly consist of generating the circular arc skeleton out of an existing transit network (given to you as GeoJSON) and producing a similar GeoJSON file as output, where the geometries are only circular arcs.
Requirements:
- You tool should be able to reproduce the results in the presentation shown above (minus the local enlargement step)
- You should write a tool that can be used from the command line.
- The output format should be the GeoJSON format used by LOOM.
Optional:
1. Deformation of the initial map by local enlargement (see the presentation shown above)
