In some cases, when performing a viewshed analysis on a feature, the elevation data for the area of interest is unavailable. However, it is possible to run the analysis by using the Viewshed tool from the Ready-To-Use Services in ArcMap.
Note: The tool consumes one (1) credit for every 1,000 input features.
The following instructions describe how to perform a viewshed analysis without elevation data.
Note: If the point data is in an Excel file, refer to Adding x,y coordinate data as a layer to import and display the points on the map.
Note: The output layer from the Viewshed tool is a temporary polygon layer. To make the layer a permanent layer, the data must be exported.
