Geographic Information Systems Asked by FrancisLi on December 24, 2020
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?
Trhough formula :ZoneNumber = floor((LongTemp + 180)/6) + 1 I calculate zone for the point.Then I got the right ZoneNumber.

Have you tried to add the s_srs parameter? Input epsg is 4326 but perhaps the geotiff CRS definition is not the standard expected from GDAL.
Moreover are you sure about the t_srs parameter? Are your data on UTM12N zone?
