[gdal-dev] ECW in Southern Hemisphere

[Andrew Williams]

It sounds like there is a companion file like a .PRJ, or something that is telling ArcView what to do with the image. Having no CRS in the ECW it's probably causing QGIS to just attempt to load the file and do the best it can.

Perhaps enquiring as to whether a companion file exists with the ECW set and then pushing this detail into the ECW header using something like ECW Header editor from ERM will correct the issue.

Subject: [gdal-dev] ECW in Southern Hemisphere

I need to assist some agricultural projects using QGIS, and located in
the Southern Hemisphere. They have a large set of ECW imagery which
displays "up side down". It looks as if the images are rotated around
their northern edge.  The northern edge is at the bottom of the map, and
the southern edge at the top. Hope I've explained myself...
The imagery has no CRS in the metadata data but they are located in
UTM40S. The same images in Arcview display correctly...

Any ideas how to overcome this would be greatly appreciated.

Thanks,
Micha
