Bye Frederik Interesting, ok, well the Europe limit is fine, I want this for the UK. but the up to 60 minutes thing makes it a tad useless for what i need. I presume that's for performance reasons? is the code for that feature available? thanks! - daniel ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I presume that's for performance reasons? I guess so, I'm not one of the operators. Some time ago I have experimented with a Perl script that did similar analyses and was able to cut memory usage and computing time by simply dropping everything smaller than tertiary roads, which is perfectly ok for an analysis in the 3 hour range. is the code for that feature available? The openrouteservice code is, as far as I understand, still under lock and key but scheduled to become available after the author has got his degree (it seems that there's a problem in academia with publishing some things too early). The Perl script I was talking about is theoretically available but it was a relatively crude thing that I did for a customer and I'll have to remove hard-coded customer data from the script put some documentation in before I can put it in SVN. (I could quickly generate a 3 hour radius around some place if you tell me the coordinates of that some place though!)

Have you seen the commute maps? http://radar.oreilly.com/2008/01/dynamic-timetravel-maps-from-m.html (scroll down to Flash portion of page) Admittedly they only calculated those for London and Cambridge :( ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

How about this? http://graphserver.sourceforge.net/gallery.html 2009/1/10 Daniel Taylor daniel.tay...@danielt.com: Hello, I've spent the last couple of days on google maps dragging around map pins and using the fancy ajax live updating distance/time calculator they now have to find locations 3 hours away from a specified location. I am looking to move house, but have to take into account commuting distance to and from work. Using google maps I was able to place a map pin on a work location and drag a second pin around (using the nifty 'drag to change the route' feature) to a few locations I was considering. Now this is all when and good when i know exactly where i want to go, i can check very easily if its viable. but... I'm not 100% sure where I want to be, I just want to be within 3 hours of my work place. So here's the insane idea. Given a specified POI all routes 'outward' should be tested until they reach the '# hours' limit, taking into account speed limits of course, this would produce a circle (more like a 'splat' shape I predict) which when overlayed on a map would show the town/cities in reach within # hours driving distance. To me it sounds like a perfect google SoC challenge, a student project or just a project for some who's a little bored this weekend. I think this would be a really cool tool to have, think plenty of people would use something like this. now... usually when i have ideas someone has already made them into reality... hoping that's the case here ;) really need this. thoughts? thanks - daniel ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk -- Regards, Thomas Wood (Edgemaster) ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
