Unfortunately, the "easiest" way is fairly involved and time-consuming. You need to set up PostgreSQL, PostGIS, and Mapnik on your own computer, then download and import the OpenStreetMap data into the PostGIS database. Richard Weait has a guide to doing that on an Ubuntu Linux computer at http://weait.com/content/build-your-own-openstreetmap-server . I was able to follow the directions on a Debian install without much problem. Other distributions are probably going to be more different, and you're probably on your own if you run OSX or Windows. After you've gotten rendering working with the stock osm.xml file, you can start experimenting with the rules to get the rendering you want. If you have changes you'd like to see made to the main slippy map, open a ticket at http://trac.openstreetmap.org/ and include a diff to the osm.xml file that will make the requested changes. (You can, of course, just request a change without supplying a diff, but the less work that other people need to do to make your change, the sooner it'll be acted upon.) -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- Your stdio isn't very std. -- Perl configure script ---- --- -- _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
