[gdal-dev] trying to fetch the data from raster and assign it to the polygon attribute

[Kyle Shannon]

You can specify the fieldname after the layername, see the documentation:

http://gdal.org/gdal_polygonize.html

gdal_polygonize.py [-8] [-nomask] [-mask filename] raster_file [-b band]
[-q] [-f ogr_format] out_file [layer] [fieldname]
