Thanks, Brent and Paul for your suggestions.
I just tried gdal_polygonize.py and the result looks OK, but the lines are
very jagged.
I also tried gdal_contour and it has the option to create polygons. And
that result is looking better.
And gdal_contour is also easier to call from a C# application
I have done this with QGIS, if you have a grid with categorised values, QGIS
can generate a polygon shapefile with the cell boundaries merged by cell value.
QGIS uses gdal_polygonize.py under the hood to do this (via a simple GUI
interface), so if you work out the command line parameters you nee
If you have the raster version, what about this

Hello List,
I'm working on a C# application that uses Golden Software Surfer to create
maps, but I also need to export the data to a polygon shapefile.
Unfortunately, Surfer creates a shapefile with shapes on top of each other
instead of inside each other, and Golden Software support couldn't help
