Hi,<br> <br>I would like to convert certain time slices (records) out of a netCDF file to a Shapefile.<br>The netCDF file has 7> GB, so what is the best proceed to get an appropriate performance?<br>I mean, should the data be cached (e.g. in an ASCII file, ...) before writing a Shapefile or can the shp directly be generated?<br>
Perhaps you have some experiences...<br> <br>Thanks for your help!<br>Best regards <br>Manuel<br> <br> <br> </div>
