Hi, Is it possible just to download certain layers from a map? for example, if I required a network file with Motorways, Trunk Roads, Secondary Roads, and Primary roads as the links, and intersections as the nodes, is it possible to download this data without all of the other information? How would I do this? Thanks in advance. asked 05 Feb '12, 19:23  schaggs |

Take a look at Xapi. answered 05 Feb '12, 19:47  Gnonthgol ♦ |
No, OpenStreetMap doesn't do that kind of data processing. You will have to download the full data set and then use a tool like osmosis or osmfilter (for both, see wiki.openstreetmap.org) to extract the bits you want. On downloads.cloudmade.com they also have pre-produced "highway" extracts for various countries/areas but these will include lower-level roads as well. answered 05 Feb '12, 19:48  Frederik Ramm ♦ |
How much of an area do you want the data for? If a small area, Gnonthgol's approach may be suitable, if not, Frederik Ramm's.
