The netcdf files I looked at through the GDAL driver had time and/or depth offered as different gdal layers, and offered different variables (i.e. different coverages) as subdatasets. Which other GDAL drivers give direct access to time-varying raster stacks in single files? > > Even > -- Edzer Pebesma Institute for Geoinformatics Heisenbergstrasse 2, 48151 Muenster, Germany Phone: +49 251 8333081 _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
