[GraphHopper] Any ideas to convert shape file to routable osm data?

[Stuart Adam]

Hello All

One approach might be using the gdal ogr2ogr tools to convert the shapefile to a gml file.  The readers I have been creating in engaric/graphhoper for Ordnance Survey formats are basically readers for gml 2.X and 3.X files so with minor modification might handle custom shapefiles converted to gml.  I am starting to consider how to start prepping pull requests for some of the work done but I am relatively new to git/github and suspect it may be a case of you wouldn't start from here.

Sincerely
Stuart Adam
