As I couldn't put a Mapnik-Ticket in the trac, I'm trying to contact you via Email. The most serious issue IMHO is the missing squares. Mapnik unlike Osmarender renders highways that are tagged with area=yes just with outlines. As squares are very important for the grafical appearance / for orientation, this should be very nice to have also in Mapnik. This is also a problem for buildings, that share nodes with surrounding areas and by now are cut by overlappings from highway-outlines that should be areas instead. I don't know, but I seem to remember, that some of the features listed down here once have been in the Maps, anyway, at the moment they aren't but would be really nice to have. There are some features missing, that I would love to have in Mapnik, the following amenities: - pharmacy - drinking_water (there is a icon here, which is according to this page PD: http://wiki.openstreetmap.org/index.php/Talk:Proposed_features/Potable_Water: http://www.blm.gov/nstc/mapstandards/downloads/inter.pdf number 37) - telephone - theatre - cinema - university - fuel - arts-centre - fountain and also historic: -monument -ruins -archaeological_site and man_made: - lighthouse - tower railway: - subway_entrance shop: - bicycle - book (is still a proposed feature, unlike all the others mentioned above) also I suggest to put bicycle-paths generally above streets in the render, as they are dottet lines and allow to see the streets that lie underneath in cases, where bicycle paths follow the street in a narrow distance. For areas instead, this should not apply, as squares are often represented as highway =pedestrian, area = yes, with highway= <some car accessible street> running over it to show the actual traffic possibilities. Some days before I also experienced a problem with churches, who would on highest zoom level display only the icon whilst one zoomlevel below show also the name, but today, this wasn't there any more, so maybe it's already corrected (but still some churches don't even show their name on any zoom level). of course it would also be great to have relations in a more advanced way, but this will be more work to implement, I guess. (e.g. someone put all river segments in Rome into one relation (41,8014855 12,3865226) with the result, that it doesn't appear on the map any more). best wishes and thanks for any reply, Martin _______________________________________________ Mapnik-devel mailing list [EMAIL PROTECTED] https://lists.berlios.de/mailman/listinfo/mapnik-devel -- Nick Black -------------------------------- http://www.blacksworld.net _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
