Why would it? My expectation OSM for China, or all regions in general, is produced with same tools and workflows, hence results should be the same. Unless, of course, a distorted positioning is at the source, which Beidu is AFAIU. But GPS is working the same round the globe, so in China it should render the same accuracy as elsewhere. Or am I wrong? > Also, I've always had success with the routes created on Kurviger and > downloaded to my phone to use in OsmAnd. > That's exactly what I do for my rides. It works like a charm. Most usually I navigate by the track, but for Osmand calculated route, I tend to export also a route with additional waypoints. I did import the route shared by Kevin and it displayed correctly in my Osmand AFAICT. It could be navigated by it, which has some shortcomings compared to Osmand calculated route, but works reliably. As Bert mentioned earlier, the track is not snapped to underlying road, which is in purpose, and voice navigation may be a bit annoying. I usually switch it off for onroad riding, but have it on for offroad. There's too much to observe on the ground offroad to look at the screen when riding :) Anyway, this RwGPS service has an option to export cues (a paid feature) and a route (free) based on cues. Although cues are not that useful as waypoints they can be used to calculate the route in Osmand. I found that they are misplaced though, which makes Osmand calculate this particular route to be ~100 km longer. If you look into it closer, you'll notice a lot of circles and turnarounds. Another thing is the routing engine used, As mentioned by Bert, you might get a better result with bike profile and tuning it a bit with riding preference. If navigating a track is not acceptable and you really want Osmand to calculate the route you'd need to do some homework. I'd start with the track, add cues to it manually as waypoints (gpx is a text file) and tune them (delete, move) to get a close result while using a relevant navigation profile. You might also import the track into other service like Kurviger or GPSvisualizer to make the work more comfortable. At the end what you need is a route for Osmand to calculate based on waypoints. -- You received this message because you are subscribed to the Google Groups "Osmand" group.
