TileSeeder
Design for a python based GUI program for tile management.

I’m involved in EduGIS and one of the nice things about this project is that we have hundreds of map layers. However that begins to pose a problem for us; to produce a decent speed for classes full of schoolkids using it at the same time we are using tiling.
We currently use TileCache; a very nice and quick open source tilecaching program. However we keep adding layers and we need those to be quick when students are using them, but we don’t have the capacity to prerender (seed) everything, nor to do this on the fly. Since we mostly have dutch data, served at dutch students, we figured that we only need to seed a certain set of tiles; the entire country for the higher levels and the rural areas a bit deeper and the urban areas even deeper.
So I came up with the idea to create a desktop application to make it easier to create a complex seed that does more zoomlevels for certain areas and less for others.
Thanks to generous development time invested by Christian there is a first alpha available around foss4g at googlecode
