Hi Joane -

You have what appears to be a very old copy of the SharpMap source. When was the last time you got an update?

ExecuteIntersectionQuery is the way to do it. What is the problem you are encountering?

its produce the exception "NotSupportedException: Specified method is not supported." for few shapefile , but not for others.

i cant query at all

the problem is about the NTS provider, still cant solve it
but the executeIntersection query already work out

really thanks
