Hi there, I am writing to check how to perform SNAP and DISSOLVE function by PostGIS.
I have a point dataset table and a MultipleLineString dataset table. I need to snap all the points in the dataset to the Line Strings when the distance is within 100 meters. I also need union some polygon features and dissolve the polygons within a polygon. Any inputs would be appreciated. -- Sincerely, John Zhang, M.Sc., B.Sc., A.Dipl.T. email: [EMAIL PROTECTED] Phone: 604-998-1874 URL: http://ca.geocities.com/john_z04/JOHN_ZHANG_GIS.html
