I have a GeoTIFF image in WGS84 and when I try with gdalwarp to reproject to UTM, it has a problem.

Size of TIFF is J: 15769, W: 60027

J_LeftTop:2.0705046510  W_LeftTop:0.4974727391;
J_RightTop:2.0702337994 W_RightTop:0.4996621899;
J_LeftBottom:2.0760866619    W_LeftBottom:0.4980068600;
J_RightBottom:2.0758219229 W_RightBottom:0.5002002912;
J_CNT:2.0731617464 W_CNT:0.4988380007

When I try:

gdalwarp -t_srs '+proj=utm +zone=12 +datum=WGS84 +units=m +no_defs' test.tif test_utm1.tif

ERROR 1: Too many points (10201 out of 10201) failed to transform, unable to compute output bounds.

What should I do differently?

    Please provide more info on the source file, as reported by gdalinfo and gdalsrsinfo. Especially the extent and corner coordinates. – AndreJ Apr 22 at 6:57

    most likely problem is that your map is not in UTM12 (-114.0 0.0, -108.0 84.0) – Ian Turton Apr 22 at 7:42
  • Where on Earth should the data be placed? – AndreJ Apr 22 at 16:50

Trhough formula :ZoneNumber = floor((LongTemp + 180)/6) + 1 I calculate zone for the point.Then I got the right ZoneNumber.
