GDAL gang, Something to put on the wish list for the NetCDF driver: the ability to write the data in chunks to the NetCDF file to conserve memory.
I've got a big geoTIFF (20,000 x 15,000) that I wanted to convert to NetCDF, but ran out of memory: gdal_translate psdem_2005_geo.tif -of netcdf psdem_2005.nc Input file size is 20000, 15000 0ERROR 2: CPLMalloc(): Out of memory allocating 1200000000 bytes. The GMT driver (which also produces NetCDF, but with Z as a 1D array) works fine. It looks like the NetCDF driver is trying to allocate the entire array, which is unnecessary -- the data could be written to the NetCDF file in rows or groups of rows instead.
