[ gpsdrive ] GPSDrive with Mapnik and OSM: claims "No map available for this position"

[Ross Scanlon]

Hi All,

For me in the file gpsdrive mapnik.cpp at line 45 there is a section of code commented out.  

It starts mapnik::projection Proj("+proj=merc +a= ....");

I uncommented this and commented out line 44 that has mapnik::projection Proj("+proj=merc +datum=WGS84");

This resolved the issue with incorrect location in mapnik mode and did not affect any of my other map tiles (google).

I used the -m switch when putting the osm data into the database.
