Automatic walking/cycling route generation from OSM maps
Build it using sbt:
./sbt "project routeSite" compile shell
Launch the app on localhost:8080 with:
(it will expect a route graph called 'default.bin.rg' in the repo route directory. I use a symlink to oxfordshire.bin.rg for development)
./sbt "project routeSite" "container:start" shell
The OSMlib project has the framework for parsing and aggregating the various datasources and building the routegraph (built as various applications). It also provides the algo for routing used by the web site.
The routeSite project has a Scalatra web backend, almost entirely serving JSON. Then in routeSite/src/main/webapp/static you can find the majority of the webapp.
You can build a fat jar of the whole site for deployment (including all static html, js etc packed as resources) using the command:
./sbt "project routeSite" assembly
The resultant jar will be assembled as:
./routeSite/target/scala-2.10/routeSite-assembly-0.0.1.jar

gdal_translate is very handy for transforming input datasets between various gis formats.
