Hi Stephan and all,
I'll setup the new system and familiar with it. Fabian already has
efficient JTS data types for manipulate Geo-spartial data. Hope to
implement features gradually.
1) Implement a code to read OSM(open street map) data and GPS log
traces.
2) As the first step, implement to find a geo-location to what region
it belongs to.
