Hi!
I have set up a rendering chain with mapnik on Windows, using an extended version of the generate_tiles.py in the SVN. Mapnik renders a foreground and a background which is merged with a pre-rendered hill shading tile into a single result tile. While the result looks satisfying (http://www.nop.onpw.de/), a single 1°x1° segment has ca. 17000 tiles and rendering it takes more than 12 hours on my 4600+ 2GB double core. In order to speed up the process to a point where updates of a map of any useful size are possible, I need some ideas. I have already moved all temporary files to a ramdisk. I have heard about metatiles, but I lack the understanding of the math to implement it myself. Are there any examples for this? Any other ideas? bye Nop _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
