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 with this issue.
I have a grid-file in Surfer Bin Grid format that can be converted to other raster formats, a border shapefile created using ST_Convexhull, and a text file indicating the values of the polygons. [image: image.png] Can anyone recommend a way to use GDAL/OGR to make a polygon shapefile from these resources, or suggest an alternative approach? Regards, Paul
