Hi. In the example mapnik.txt TYP file, the draworder of the polygons for woods/ forest 0x50 and wetland 0x51 are given like this: [_drawOrder] .. Type=0x050,3 .. Type=0x051,2 .. [End] When compiling a map, this means that wetlands in forests are not visible if this TYP is used. I tried makling a map using the same draworder Type=0x050,2 Type=0x051,2 plus using the option --order-by-decreasing-area This makes the wetland visible in forests. I could not see any negative impacts of this in the areas which i checked (a few in Sweden and Norway). Wetlands over other areas seems to work fine as well. Do you think such a change would be of help or is there a great risk that this type of change would impact negatively on the drawing of the maps? Regards Karl
