MX Simulator

I Am trying to replicate a local track in germany. The only problem for me was making the hight map ive tryed so much and Looked it up on youtube but I still couldnt figure it out.
So somebody would make me a big big favour with making the hight map for me. If somebody is willing to help me out, the track doesnt really have an adress so just copy this in to google maps:
Motorsportclub Wieslauftal
Thanks so much i‘d really appreciate it

The YouTube tutorials using sketch up etc don’t really work anymore, your best bet is to put an screen cap from google maps, top down as an overlay on the track and try replicate it yourself. There’s another Method using NASA height data but I wouldn’t know where to start with that.
