I've been having problems getting gdal to work with netcdf files.
Using Ubuntu 8.04 LTS (Hardy)
1. problems with libgdal 1.4.4
First i tried the default gdal versions and libraries installed through Synaptic Package Manager. The packaged version was gdal 1.4.4
All programs that called gdal - Grass (using r.in.gdal), FWTools and gdalinfo, gdal_translate etc -
gave me a 'segmentation fault'
I then looked up online and this bug report seemed to say it was a fault with how gdal is packaged by Ubuntu - https://bugs.launchpad.net/ubuntu/+source/libgdal-grass/+bug/126916
and the recommendation was to compile from source. So then on to part 2
2. I compiled from source gdal1.5.2 from
using the following configure
./configure --with-netcdf=/usr/lib --with-libtiff=yes --with-geotiff=yes --with-jpeg=/usr/lib --with-gif=/usr/lib --with-png=/ur/lib --with-pg=/usr/bin/pg_config --with-libgrass=yes
sudo make install
and made sure the libgdal link was referring to the new one.
and again got 'segmentation fault'
it works for other data types; only netcdf does not work (just like before with gdal1.4.4)
How can i fix this problem? I am not a linux expert by the way...perhaps that was obvious:)
The .nc file is very large - It iss climate projection data from the California Climate Change Center. All i want to do is automate the extraction of climate data for a set of points - am trying to do the following:
- import .nc data into Grass rasters or GeoTiff with bands = images on the netcdf file
- run a small script to extract climate data for vector point data from each Grass raster/GTiff
