Any chance there is a solution that doesn't require the 3D analyst extension? Any scripts out there perchance? Cheers, Dave

Well the ouput I would have hoped for would purely be a VISIBLE or NOT VISIBLE result for each pixel of the DEM/DTM depending on whether ANY of the polygon is visible. I am currently converting polygon observer features to a grid of point observer features, but the processing time is long when analysis is performed this way.

Thanks for the response. Converting the feature data to a raster and "Plus"ing it to the DEM is what I do currently, but I wanted to find a way of improving the resolution of the screening features without resampling the DEM to a higher resolution and potentially crashing the analysis. Additonally, I'm guessing that it is also not possible to run a Viewshed analysis using a polygon as the observer feature? I know that the Viewshed tool works with point and polyline features but I just hoped that the 3D analyst features were advanced enough to cope with 3D features in the analysis. I'm sure I've seen it done with skyline analysis so why not Viewshed? Cheers

Is it possible to run viewshed analysis on a point/polyline/polygon feature, with a GRID DTM surface, but including screening objects (trees/buildings etc) that are respresented by 3D polygons? Can this be performed in either 3D or Spatial Analyst? Regards, Dave Brooks
