Hi, I'm trying to set up a Mapnik server with a transparent contours overlay. I've succeeded in getting the mapping data imported into postgis along with the contour data for the region I'm looking at. Initially, I imported the UK data and noticed that there were odd things going on with the contours in various places. Thinking this was just bad SRTM data, I imported the data for switzerland (so I could compare with OpenPisteMap) and am seeing the same thing. I've got a picture of how it's rendering:
http://img66.imageshack.us/my.php?image=mapky8.png Both the map tiles and the contour tiles were rendered with the generate_tiles.py script. There are two issues. The first is apparent from the image - the contour lines aren't being rendered in some areas. The other I noticed when looking at my UK renderings - in some cases contours weren't plotted above a certain height, leading to lots of "plateaus" in what should be quite a hilly area. I've rendered these both with the script and with mod_tile, redownloaded and imported the data and with the same result. Any ideas what's causing this? Thanks, Andrew _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
