[mapserver-users] Can't get a raster to display... projection issue?

[Jeff McKenna]

Peter,

Some things I would do when hitting that wall:

- remove all projections blocks
- use the coordinate values from gdalinfo in your EXTENT block (lower
left & upper right)
- change to UNITS DD
- remove all other LAYERS except the problem layer
- then test with the shp2img commandline utility
