topic Adding Height Data to Point for Viewshed in ArcGIS Pro Questions https://community.esri.com/t5/arcgis-pro-questions/adding-height-data-to-point-for-viewshed/m-p/1294030#M69675 <P>Hi, I want to know from where in the surrounding landscape a building would be visible. I am using viewshed (spatial analyst). I use 1.75m on surface offset to account for a human in each cell. However, I need to add the height of the point (building). Am I correct in thinking that I need to add a field OFFSETA to the attribute table so that the analysis can take account of the point/building height e.g. 6m? Or am I doing this wrong?!&nbsp;</P><P>many thanks</P> Tue, 30 May 2023 13:29:50 GMT NeilGodfrey 2023-05-30T13:29:50Z Adding Height Data to Point for Viewshed https://community.esri.com/t5/arcgis-pro-questions/adding-height-data-to-point-for-viewshed/m-p/1294030#M69675 <P>Hi, I want to know from where in the surrounding landscape a building would be visible.
