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.
