[gdal-dev] netCDF to Shapefile

[Manuel Rainer]

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

Manuel,

Shapefile is for vector formats alone. 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.

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!
Best regards 
Manuel
