in my case, I had elevation markers. I know highest and lowest elevation points on track. so I scaled height map generated mesh until those two points met and that's is how I scaled Z axis.
"Jules Tacheny" track seems relatively flat, it should not be too hard. but for hills, I do not know how to help u to scale terrain. maybe there is some known elevation markers, exact sealevel for "Jules Tacheny" maybe, it would give you some starting point. here I found Belgium topographic map, find your hill and use this map to scale your terrain
I could not make GIS plugin to work and I did old fashion way, manual labor.
as for drone, I have none. I used drone footage that I found in internet. that's pure luck.
anyhow, I am very happy that there is someone in this community that shares same skills, wish you good luck with your project and if you will need to talk to someone about it do not be shy write me a message or something
Wow! I'm in awe, this is simply amazing. Thank you for staying so dedicated and persistent towards pushing LFS to improve! I hope scawen sees this and actually considers this
huh, appears they have somewhat accurate representation of track. if there is interest, officials can write to provided email, what are the terms to get data...curious if they will provide data to individual, but doubt that. maybe I will write them. good find tho
Funny how much time has passed. I actually thought of this thread when the state of Rhineland-Palatinate went open data for good chunks of their geospatial information but it was inactive at the time.
If you search for “Geländemodell” at https://www.geoportal.rlp.de you find a dataset with a sparse point cloud in x y z ASCII of the whole state. That might be handy for the terrain modelling. However it is only with a grid width of 25 m. So it really is quite sparse.
