First, please accept my apologies. I'm sure this is very simple and has been asked many times in the past, but I've been searching and trying to solve this on my own. I'm frustrated now and need help. Thanks.

I have a terrain file. This file contains height, azimuth and slope information. I would like to extract this information into points.

Here's what I've tried:

  1. Terrain to point - this failed; points were created, but the height, azimuth and slope information were not attributed to the point layer

  2. Terrain to TIN -> TIN to Point - same problem as above; points were created, but no information was included

  3. Terrain to raster -> and then perform the azimuth and slope analyses on the raster; then join these with a points layer of my creation. This works, but it takes far too long!


The third process in my list works, but it takes forever, there has to be a simpler way, right? Thanks for all of your help! I can see all of the information in my terrain layer, I just want to get this info into a point layer in one, simple step 😞

I wish I could spatial join a point layer with a terrain layer....

The terrain dataset references data from the feature dataset it resides in, so there's no need to recreate points for it. You can obtain the slope and aspect information as polygons using the Surface Slope and Surface Aspect tools, then perform a spatial join to get them attributed to the points. If the Z values are stored in the geometry and not as an attribute, you can use Add Z Information to add it as an attribute.

Let me know if you still need help.
