Hi guys, I just cannot live with the fact that "they" have awesome hillshading in a slippy map and I cannot replicate it with Mapnik and OpenLayers:
http://www.mapy.cz/#x=132471...@y=138964992@z...@mm=rtp (that area nicely shows the tile overlays). All *I* can manage with this kind of layering is http://opentiles.com/cmarqu/relief.html?zoom=13&lat=50.9354&lon=14.20458&layers=BT or http://opentiles.com/cmarqu/relief_flipped.html?zoom=13&lat=50.9354&lon=14.20458&layers=BT (layer order changed and opacities adapted.) When you toggle their "Stínování" layer, the brightness and crispness of the map doesn't change much, it just gets hillshading. My map is very foggy in comparison. It's most likely not the thinner/smaller fonts in my map, since the "Bad Schandau" there is as bold and black as possible, but still washed out in the map due to the opacity. Their text somehow stays at 100% black. The relief layer is different of course, but not so much IMO: http://m4.mapserver.mapy.cz/relief-l/11_7e60000_8480000 vs. http://opentiles.com/cmarqu/tiles_relief/12/2209/1372.png Does anybody have a guess as to what the crucial difference is? Doing the hillshading like this could have the advantage of a smaller tile size overall, since you could reduce the number of colors needed for the roads layer. With an all-in-one tile (roads and hillshading), there are too many mixed colors which would get ugly banding if color-reduced too much. (FWIW, my all-in-one tiles are at http://opentiles.com/cmarqu/?zoom=13&lat=50.92308&lon=14.16252, done with the process that Marcin described a while ago.)
