osgeo4w - PROJ.4 strings do not work with GDAL

Reported by: tcgeophysics Owned by: osgeo4w-dev@…

Hi All,

I've using the OSGeo4W install of GDAL for a little while now and I just realized that GDAL utilities does not work when using PROJ.4 string to specify -s_srs or -t_srs. I usually defines my srs with EPSG codes and this does not give me any trouble. But I recently needed to use a custom projection and found out about the issue. I am running it with Windows 7 and I ran the commands in an OSGEO4w terminal window. The variables OSGEO4W_ROOT, PROJ_LIB and GDAL_DATA are pointing to the correct directories.

If I enter the following command:

gdalwarp -t_srs '+proj=utm +zone=11 +datum=WGS84' input.tif output_utm11.tif

I get the following message:

ERROR 1: Translating source or target SRS failed: '+proj=utm'

Any idea on how to solve this?

try quotes:

gdalwarp -t_srs "+proj=utm +zone=11 +datum=WGS84" input.tif output_utm11.tif

Replying to jef:

try quotes:

gdalwarp -t_srs "+proj=utm +zone=11 +datum=WGS84" input.tif output_utm11.tif

I did not think about that syntax issue as simple quote are used in examples on the gdalwarp manual page. Double quotes work perfectly!

The problem is that quoting techniques vary depending on the shell and the examples were prepared on linux. Perhaps double quotes would be more universal.
