Is it possible to superimpose an aerial photograph of a site onto a created Toposurface, similar to the photomatching on Sketchup?
Even Better, drape the photo on top of the toposurface. Is this possible?
That would be an amazing functionality and I would definitely like to see that in Revit as well! That being said, there isn't currently any way to drape an aerial image over a topography. The best you can currently do is import a site image, align it correctly, and make it display as foreground or background in a plan view.
If you'd like to see this added a feature, I'd really recommend quickly putting your suggestion in this form: http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1109794. This information does go to the product development teams, so it will be heard!
Thanks!

Hi Jillian
I managed to drape an aerial photo over my topography but it was a mission - create a default material, use the image as the material, mirror it, scale it, postion it... nightmare.
The link you posted opens to THIS PAGE CANNOT BE FOUND...
I've tried to add an image of the end results but it doesn't seem to upload properly...
I also previously tried doing this.. but was to inconsistent and problematic...
Yes it does give you an inconsistent result especially when you render the image you never get the same result as you see in your REALISTIC view... Attached are two JPEGS of the final result.
Thanks... it was a nightmare to get it just right but I couldn't render the model due to the photograph material I created shifting during the rendering process! It was frustrating, luckily the REALISTIC view gives you a good impression of the final product.
If you can find the time, you should really consider creating a turtorial on how you did this. It think it would be very valuable to the community. The fact that the model won't render is, I don't think, a big deal, as is the model reads very well and is much more realistic than using a "grass" or general vegetation rendering material.
I understand your basic approach from what you posted, but you must have learned a few hard lessons along the way that would be helpful to pass along. Perhaps others might even improve upon the process, then we won't have to wait for Autodesk.
Nice work,
SG.
I'll definitely draw a tutorial, it'll take a liitle time but I'll post it as soon as I'm done... but in the meantime if you want to try it out for yourself just remember, SCALE is the key. From that you can nudge and rotate the image till it fits!
Its a mission but you've seen the end result.
Good luck and I'll keep you posted.
If you scale the original 2d aerial photo as an underlay below the 3d topo, before you try to attach the image to the material, does that help you get the scale correct, or does the 3d topo deform the 2d image too much for that to be useful?

I haven't tried it that way yet... technically it shouldn't warp the image out of proportion!
Try it let me know!
I was reading the post regarding superimposing Aerial photos over topography and I wonder if you could give me more information regarding the process that you used. I have created a material with the Aerial but the image is mirrored. I noticed that you mentioned mirroring the image in your material, but I cannot find a way to do that? Am i missing something, or does the mirroring need to be done in Photoshop?
I use to insert a perspective image made in revit into a background image the following steps:
