[udig-users] Re: projection not supported: +proj=utm +ellps=intl +zone=2

[erik <whatevar89@xxxxxxxxx>]

Concerning the projection, maybe it's a problem with the raster I converted from an image with gcp's. When importing it into grass (not jgrass) it doesn't import it as a sinlge raster but as three different files (red, green and blue). udig does project it correctly when warped to WGS84. I'll have to explore this more....

Hi, I built a raster from an OziExplorer file with the following projection:

+proj=utm +ellps=intl +zone=29 +towgs84=-84,-107,-120

When I convert it to WGS84, it reads it. When I try to set it to ED50 zone 29, it doesn't accept it read it either. RenderingNull

Any suggestions?
