Hi all, attached is a patch that implements a new hook ResidentialHook to add the tag mkgmap:residential to nodes and ways which are located in a landuse=residential area. If that area was named, the tag will have the value of that name, else it will be yes. So, in the style you may use building=* & mkgmap:residential!=* [0x13 resolution 24] to add only those buildings to the map which are not inside a landuse=residential area. To reduce run time, the hook tests only one point for each element: For nodes it will check the position of the node, For closed ways the hook computes the center point, for other ways with n points it will check the n/2 th point. The hook is executed after the POIGeneratorHook, so generated POI are processed (as well as the shapes generated from MP-Relations. I did not see a reason to process relations, please let me know if you see one. A compiled binary is here: http://files.mkgmap.org.uk/download/338/mkgmap.jar The option --x-residential-hook=false disables the hook. If I hear no complains I will add docu and commit the patch next tuesday. Gerd
