Hi,

Can anyone show me how to simplyfiy polygons (I think thats 'Generalize' in ArcGis) from, say, 100 polygons down to 10.

Thanks, P.

NTS, that is used in MsSqlSpatial, has some algorithms.
Take a look:

SELECT ST.Simplify(the_geom, @distance_tolerance) FROM the_table
...where @distance_tolerance is a value expressed in the geometry units.

BTW, the NTS algorithm used is the Douglas-Peucker simplifier.
