I am using ArcMap 10.8.1 and working on an hp Probook 650 G4. I have been attempting to run a viewshed analysis using the Viewshed (3D) tool with zero success. I ran this analysis once before which took about 20 hours to complete, then tried to run another analysis on a different set of roads and after 5 days never got anywhere. I used a roads file that I used the split tool on to create road sections every 250 meters and used a 10 m DEM of the area. When this didn't work after several attempts a coworker used the same files and ran the analysis with success after less than 5 minutes.
I am wondering if anyone has suggestions to help with this? Is there something I should be aware of that perhaps this computer doesn't have enough ram to run this type of analysis or does this version of ArcMap not do well with this analysis, or even yet could there be a corruption in my computer that is prohibiting this type of analysis from completing? I am trying to understand the issue so if I take my computer to our tech people they can better understand what to look for as a diagnostic tool. Thanks!
