Thanks for the suggestions -

I just managed to run 'gdal_translate -of netCDF -srcwin 50000 40000 100 100 input.ers output.nc' without issue (the input ERS dataset is 50592 x 41876)

I may have misled people with the subject of the message, sorry about that. The issue is translating a large ER Mapper file into an equally large netCDF file (reading .ers and writing .nc)

http://trac.osgeo.org/gdal/ticket/4047

I've attached the ERS dataset header to the issue for reference, please let me know if you need more info.

Will this affect writing a netCDF? Sorry again if I've misled you, the issue is reading an ER Mapper (.ers) file and writing a NetCDF.

Thanks again everyone for your assistance.
