Hi,
I want to create a GTiff copy to a data with projection overridden to
*utm* using gdal_translate and its "a_srs" parameter.
If I try to do this I obtain a wrongly located data.
Command I use is like following:
$ gdal_translate -of GTiff -a_srs "+proj=utm +datum=WGS84
+zone= " src dst.tiff
If I try to georeference the same data with gdal_warp and the same
parameters I obtain a correctly located data, so I think the problem
doesn't come from datas neither from parameters.
What's wrong? Have I skipped some parameters?
Luca,
Are you aware that gdal_translate's -a_srs just overrides the coordinate
system definition but does not in any way adjust the geotransform? It
is only suitable for use to override an improperly described dataset, not
to transform a dataset into a new coordinate system.
Best regards,
