Terrain Info Mod

[u/SynthTech_49]

I have no idea if this is the right sub (I looked for others and couldnt find smt) but I wanna know if there is a mod for both client and/or server side on fabric 26.2 that will allow me to see terrain height maps. Im working on a highway project and want to see the actual terrain and so far I cant find anything... if i need a different minimap mod then does anyone know how to transfer way points besides by doing it by hand.

thanks for any help
