[Mapserver-users] Perl polygon shapefile tiler

[Martin Weinelt]

Dear List,

'Interpol' is a Perl script to tile polygon shapefiles using 
Sutherland-Hodgman clipping.
Resulting tiles are comparable to the tiles generated by VectorTileIndex 
Avenue script by Chip Hankley. Use tile4ms / shptree to make use of the tiles 
in a Mapserver application.

Sutherland-Hodgman clipping might leave 'unwanted' (degenerate) edges along a 
clip boundary when clipping concave polygons. I guess this is not actually a 
problem, since one would not want to draw outlines of tiled polygons in a  
UMN Mapserver application anyway. 

This first version of the script is at the Wiki: 
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?InterPol

Cheers, Martin
