Links are helpful for fastest route, for shortest may be not. Does the routing work in both modes as expected?
The "fastest" routes for cars look fine to me. The shortest routes are a little strange -- they make obvious detours. Also, the "Dist To Dest" is too low, I'm getting 15km instead of 17km for an example here. My guess would be that the arc lengths aren't all quite right.
(We're not writing proper lengths in NET at all so far, but I don't think that should be involved in routing. More likely to do with addressing.)
Headings are angle of first and second point, and last-1 vs last. Lenght should be sum of distances of all points in the line. How are lenghts calculated?
I'm also noticing that when viewing the route on the map (all my testing is on a Vista HCx), it doesn't follow curvy segments at low zoom levels, cutting them straight instead. If I zoom in, the display is corrected. So probably, there's some curviness data missing.
Are the roads present at that map level? They should be even simplified as a signle point, that is polyline with point and one zero delta. And that segment is in net. -- have fun, alex
