[Qgis-user] gps plugin

[mtnbiketrail at zzz.com]

Actually, I wanted to transform the geotiff to wgs84 utm, but all 
methods have failed.
I tried using the FWtools GUI conversion, but I must be doing something 
wrong, I can't get it to work. I also tried gdalwarp command line with 
no success. gdalwarp does not recognize the original projection for some 
reason.
