SV: [mapserver-users] Shapefiles with islands

[Lars Westerlind]

So,
How is the lack of response to be interpreted? Nobody render islands in lakes? Everybody make their own data extracts? Or there are other (for me) hidden sources of information?

Hi,
I wonder if anyone renders islands in lakes? I use OpenStreetMap Data,
where lakes are tagged as multipolygons, with islands as inner polygons.
The source I use, mainly the "Mapserver recommended" cloudmade make
simple extracts where those inner polygons are simply skipped, AFAIU.
Looks rather funny for islands that are large enough to keep some
roads...

So, what is recommended? Should I make my own OpenStreetMap extracts for
this purpose? Or does anyone have any other good sources? 

BTW,
Do I understand correctly that multipolygon files must be converted in
order to be possible to handle by mapserver? I mean, inner polygons
should have at least an extra column in the DBfile, telling it's level,
or such? 

Regards,
Lars
