I am having a hard time using new Viewshed 2. I am trying to join values from result raster with observer-region relationship table (ORRT) using Value from raster and Region from ORRT.

I couldn't find any workflow of connecting VAT and ORRT. Here is my approach: a. Convert raster to polygon b. Inner join ORRT using polygon.Region = VAT.Value c. Calculate area for polygon d. Create summarize table to show observers with areas However, I am a bit concerned of using it since there are a couple of issues you can see below.

Concerns:

1. There are duplicating Values in VAT.



2. There are negative Values in VAT and no corresponding pixels with that Values in the raster.
