Re: [Talk-in] [OSM-dev] Display Boundary area using postgresql database
Instead of setting a background colour in the mapnik style sheet, you can set it to transparent, then you just do a limited subset, then load it as a non-base layer in openlayers and see it in action here: http://toolserver.org/~osm/styles/?zoom=2lat=0lon=0layers=B000T0FFF0FFF This is good style for showing different things. I want to use overlays structure from here because i want to show the schools, restaurants, etc. of my area like showing here in overlays. How to do it? But I don't want to change base layer. i want to search the geographical information from the database(PostGIS) and show it as boundary of a area. for e.g. like i want to show the boundary of my college on the map.

Re: [Talk-in] [OSM-dev] Display Boundary area using postgresql database
First of all Thank's for your help, if you are using osm2pgsql it's almost 100% going to be x,y projection rather than lat/lon. Yes sir i am using osm2pgsql, and i will look for that functions of postGIS. Also, instead of using openlayers to plot a polygon, you can generate transparent tiles in mapnik and just display them over the top of a base layer... and sir what are transparent layers, and how can i use them. -- With Kind Regards Parveen Arora osmpunjab.co.cc ___ Talk-in mailing list Talk-in@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-in
