[gdal-dev] gdal_grid does not work in cron but works in terminal

[Davorin Bajic]

 I solved. The problem was in two versions of gdal. The gdal environment on
the terminal is set to a newer version, while CRON launches the old
version. I solved the problem so that I added the path to new versions gdal
in bash script.
