Loading STRM heights does not work properly #53
Comments
Hi, thanks for the bug report. There are a few things going on here, some of which are GpsPrune's fault. Secondly, GpsPrune doesn't deal very well with the data being out of range and doesn't show a good error message to explain what happened. This can and should be fixed, most likely with version 22. Thirdly, this should have been tested properly but for some reason wasn't, so I apologise for that.
If you don't want to see the terrain, then GpsPrune won't try to load the SRTM data. But if you ask it to show the terrain as well, then it needs to get the elevation data from somewhere ;) |
Graphoper builds a track and displays the heights, this is the track: In addition, osmand also offers to download the 500mb bump/shading map of Finland. As for the height issue with 3d, I'm in a hurry. Sorry. There are point heights for the track that you are loading and there are location heights for rendering it in 3d. |
That tells me that Graphhopper has access to elevation data for Finland, and OsmAnd has access to elevation data for Finland. That's good news, but it doesn't help you if you're in a hurry. GpsPrune uses SRTM data for its elevation lookup, and SRTM data isn't available for this part of Finland. Longer term it may be possible for GpsPrune to use the same elevation data as Graphhopper and OsmAnd, but that's longer term. I will try to find out where their data comes from. Again, GpsPrune can show the track in 3d without elevation data, but if you ask for terrain then it needs elevation data. |
Reproduce the problem: download the attached track (because it is in this area that there are problems with loading heights); remove height field value and upload heights online (I also used vpn different locations didn't help).
Used versions with the problem (v21.2 and 21.3); GNU/Linux/deb.
