I have done this but not to a shapefile direct, but into a postgis database.
Use for loops to loop through the temporal dimension, then the lon and lat
as sub loops.
Then you create an insert string to input each line of data into the sql
database.
In our NetCDF we have 720x360 observations spatial

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.

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
