Each obstacle has different heights. Any advice on the best way to achieve this would be much appreciated.</P><P></P><P>Many thanks</P><P></P><P>Lizzie</P></BODY></HTML> Tue, 02 Dec 2014 13:06:46 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-barriers-for-viewshed-analysis/m-p/255020#M3633 ElizabethStewart 2014-12-02T13:06:46Z Re: Creating barriers for viewshed analysis https://community.esri.com/t5/arcgis-spatial-analyst-questions/creating-barriers-for-viewshed-analysis/m-p/255021#M3634 <HTML><HEAD></HEAD><BODY><P>You would have to create rasters for each of your barriers and add them to the existing terrain.
