I have a georeferenced image/tiff and a TIN layer (created from elevation line fc), and want to add the elevation data from the TIN to the image. How do I do this?

I know I can float the image over the TIN, but can I add the elevation values to it also?

I use ArcGIS 10.3

  • Why do you want to do that? At first sight it's not an efficient data structure. – GISGe Oct 5 '16 at 9:36
  • I need to use the georeferenced photo (a recent ortphoto) to estimate the changes in elevation after this specific area recently was excavated. – Sil Oct 5 '16 at 9:56
  • You don't need to have both elevation values in the same raster to compare them. I would convert the TIN to a raster, then use Cut/Fill or Minus to detect the changes. – GISGe Oct 5 '16 at 10:01
  • But the georeferenced image has no elevation values, only xy. – Sil Oct 5 '16 at 10:02
  • So how do you want to compare elevation? Visually? – GISGe Oct 5 '16 at 10:04

I don't really see the added value to having both images in the same file for visual analysis purposes, but you can do this:

(Combinatorial Or is a useful tool to create unique combinations of values from 2 rasters (these have to be integer, so you might want to multiply elevation rasters by a constant to delete decimals while maintaining accuracy). But since your image doesn't have values, it isn't applicable here.)
