[mapserver-users] Maximum number of points in a poligon

[Sebastian E. Ovide]

Hi Lime,

I cannot release the shapes (I am sure that you understand) but I can tell
you how I've created them. Using gdal_polygonize.py on a raster big as UK
with only 2 colors: 0,1. Each pixel is a 5x5 meters squares. The Image
displays the UK water surface. The bigger polygons belong to the coast.

Regards
