Hi all,
just a feature check of Mapserver.
Should Mapserver read the projection information in the geotiff header, if
PROJECTION is not set in the LAYER def. of the map file?
I'm testing with Mapserv 5.1-dev, and it's not working without PROJECTION,
only when PROJECTION is set.
I will soon try with a recent version of Mapserver (compiling).
Jørn,
MapServer does not ask the underlying data source for coordinate system
information by default. However, you can setup a projection block like:
PROJECTION
"auto"
END
to automatically read the projection through GDAL. This is a little
used feature, so it is possible it is broken now. The normal projection
block for your coordinate system would look something like:
PROJECTION
"+proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs"
END
If it is intended to be "google mercator" then you should use:
PROJECTION
"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgri...@null +no_defs"
END
Best regards,
