[OSM-talk] gdalwarp question

[Torsten Mohr]

Hello,

thanks for that hint.

Right, the chosen projection won't work around the poles, i don't expect
that.  In the call to gdalwarp i gave the source projection (EPSG:4326 or
WGS84) and as target projection i gave the projection used in osm.xml.

But the result is not what i expected and i also can't explain it.


Best regards,
Torsten.
