How to set the GDAL_DATA environment variable to point to the directory containing EPSG csv files?
I want to wrap(re-project) one variable in this netcdf file.
D:\ gdalwarp -t_srs EPSG:4326 NETCDF:"C:\fie.nc":var "C:\Desktop\SM.img"
But I get this error:
ERROR 4: Unable to open EPSG support file gcs.csv. Try setting the GDAL_DATA environment variable to point to the directory containing EPSG csv files.
ERROR 1: Translating source or target SRS failed: EPSG:4326
I am using GDAL 1.9.0, released 2011/12/29. I will be grateful for any help.
Answer
You can edit the environment variables graphically in Windows (e.g., this, or this).
Add a System variable with name GDAL_DATA and value of the path to the shared GDAL data (a folder with a several files, like coordinate_axis.csv, gcs.csv, pcs.csv, and other files).
To make the environment variable effective, you need to run cmd.exe, or log-out, or other method.

Anaconda / Miniconda users
GDAL library and command-line tools are available via (e.g.) conda install gdal
The GDAL_DATA variable is properly set when the environment is activated. This is done for you if you start an Anaconda Prompt, otherwise you can activate the environment as documented.
