Hello, My whole idea is to find suitable locations for a picnic site as far as 50 kilometers driving from home :) It would be nice if that software can also choose highways that are only for "driving" like primary, secondary, trunk, etc. http://www.mapnificent.net is something like that, but there are limited numbers of cities around the world. And it measures not by distance but by time for travel. And it uses Google Maps, not OSM. |

There's a script in OSM SVN that does that, here. It will require some Perl skills to get it to do your bidding though. |

It's funny you'd ask this, because this is exactly what I was researching this morning. If you'd like to import your OSM data into a PostGIS database, you can use the pgRouting project which has a driving_distance() function which does exactly what you're looking for. Here are some references to get you started.
If you'd like to search more on this subject key words to search are driving distance (even though the cost can be anything, like time, distance is most common), and catchment area. |
