I've tried the QGIS-user listserv to no avail. Figured I'd try here, perhaps at least I can get forwarded to the right one.<br><br>I
have an ECW that does not seem to want to accept a CRS definition.
Initially I was attempting to warp the ECW file from Michigan Georef to
NAD83 UTM zone 17. I got an error.<br>
<br>ERROR 1: Unable to compute a transformation between pixel/line<br>and georeferenced coordinates for /home/lee/documents/gis/<div id=":1rc">detroit/aerial/WYANDOTTE_NE/WYANDOTTE_NE.ecw.<br>There is no affine transformation and no GCPs<br>
<br>QGIS shows a generated CRS that seems right for Michigan Georef, it
just does not seem to recognize that a CRS is there, so I cannot warp to
the new projection. Next, I tried manually assigning the CRS in
question so I would then be able to convert.<br>
<br>gdal_translate in.ecw out.ecw -a_srs EPSG:3078<br><br>This creates a file, but one which is un-readable in qgis. <br><br>I
am not exactly sure which is the problem that needs fixing here.
Essentially, I just need to find a way to get this ECW file (in Michigan
Georef) as any format (in NAD83 UTM zone 17). So whatever suggestions
you have for accomplishing this, I am willing to try.<br>
<br>Thanks for any help in advance.</div><br clear="all"><br>-- <br><div>all the best,</div>
