Thanks for your help, it has to be a Shapefile because we do some further processing (symbology, map creation...). The netCDF file contains hydrodynamics point data. Best regards Manuel

Try a raster format to convert the netCDF data. As for the performance, you don't need to cache anything. But it may help to tweak the GDAL_CACHEMAX setting. http://trac.osgeo.org/gdal/wiki/FAQRaster#Howtoimprovegdalwarpperfomance On Wed, Mar 16, 2011 at 8:21 AM, Manuel Rainer <manuelrai...@hotmail.com> wrote: Hi, I would like to convert certain time slices (records) out of a netCDF file to a Shapefile. The netCDF file has 7> GB, so what is the best proceed to get an appropriate performance? I mean, should the data be cached (e.g. in an ASCII file, ...) before writing a Shapefile or can the shp directly be generated? Perhaps you have some experiences... Thanks for your help!
