fit an aerial image on toposurface?

I've done this in the past. I'm sorry I dont remember exactly the process, but it was a pain to get right.

At least I remember that you need to split the toposurface rectangular and scale the image exactly as the toposurface or it would be all screwed up.

If you add a grass key word to the material you will get a nice effect close to the ground

... hmmm - ... and even if you have almost reached this desired setting (also in SketchUp!) Enscape´s self-active unauthorized and wrong and annoying camera 180° rotation flip destroys any own effort here
Surprisingly isn´t it ? Jorgensen´s desire is nothing more than an essential camera setting and need of Enscape´s target group

In Revit it is not possible to line up textures on a topo surface. You can achieve this with a floor, however it will not be contoured.

This is not correct. I just did a new take on this yesterday. I used a high quality orthophoto that I cropped to a rectangle with the same exact scaling as a rectangle toposurface. Further I needed to mirror the image (some strange Revit thing). Then I scaled the image in Revit material editor and the image was spot on.

Very interesting. I will try that method. Thanks for sharing.

I did manage myself - by adjusting the coordinates and rotation - it did take a lot of time.

I also had to mirror the texture

It should not be neccesary to do any offset on the coordinates as long as you crop the image and the toposurface to the exact same size and scaling. However you might need to rotate
