[gdal-dev] Newbie question about gdal_grid for 3d data

[Brian Case]

Andreas,

There are no vector drivers for hdf and nc. take a look here
http://www.gdal.org/ogr/ogr_formats.html

As an alternative to gdal_grid you can use GMT's blockmean, blockmedian,
or blockmode. then use GMT's surface http://www.soest.hawaii.edu/gmt5/
