[mkgmap-dev] Inter tile routing

2010-01-08 Thread Stefan
Hello, in the archive (september 2009) I saw that there were some discussion about inter tile routing problems. I use version 1445 and have the same problem when doing a routing in Mapsource over 4 interceptions. 3 interceptions working fine. Are there some news about that issue? Another

Hi Michael, --ignore-osm-bounds If you ignore the bounds, the ways don't end at the same coordinates. Cheers, Mark ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev

MB I haven't the faintest clue what could be the issue here so until we MB get some hint as to what the problem could be, I'm ignoring it. MB I simply don't have spare time to dream up possible reasons why MB this problem exists. Can't say I blame you, doesn't sound like an easy one to get to the

Hi Chris, When I get a chance in the next couple of days, I'll have a play around with some of the official Garmin maps and see if they can be made to exhibit the same problem. If so then the limitation is most likely in the routing algorithm in MapSource and/or on the device. If that's

Using a recent GB tiled map on my eTrex, I have found that it performs differently (better?) to mapsource with regard to the problem of not routing across a boundary and back to the source tile. An example route I tried used a road that snaked across a boundary. Mapsource failed miserably in the

did some experiments in Mapsource and Garmin maps don't suffer from this problem.found a place where the direction of the route defines which way is chosen. makes perfect sense because right turns are faster and easier than left turns. Mapsource will even choose the longer way across the tile
