How can you perform an observer point analysis using the WorldElevation3D/Terrain3D elevation surface?

Hi all

I'm trying to perform an observer point analysis, like in this video, minute 14:39: https://www.youtube.com/watch?v=BRqnRcZ-ajQ

I think the guy in the video is able to perform the observer point analysis because he is only analysing a small patch of the world, whereas if I try doing it with the WorldElevation3D/Terrain3D elevation surface, the analysis will take days since it is technically doing it for the entire earth. (If you look at the screenshot I attached to the post, you can see the analysis remains stationary at 0%).

How can I solve this problem? / How can I tell ArcgisPro to only analyse a specific section of the map (the province of Asturias in Spain)?

I'm new to ArcgisPro, so please keep your answer as simple and step-by-step as possible if you can

Thanks for your time

Jaime

Hi,

If you're using the World Terrain you will want to specify an extent in the tools environments to avoid processing the entire globe.
