I'm doing a viewshed study to be published online for sharing. My workflow is: Pull in DEM, Drop Points for Observers, Interpolate shape on observer points, Adjust Z (for the height of antenna, in field "OFFSETA") for observer points (this is so it looks better when published online), Run Viewshed (OFFSETA for antenna height).
My question is: Does the viewshed use the z value in the point for the analysis. Am I accidentally using the offset height twice by adjusting z value and using OFFSETA in the analysis?
Thanks,
Matt
