Creating barriers for viewshed analysis

[ElizabethStewart]

Hello everyone

I am trying to do viewshed analysis from various points but there are several obstacles that I would like the viewshed analysis to recognise, e.g. walls, buildings, tree coverage etc. Is this possible? Each obstacle has different heights. Any advice on the best way to achieve this would be much appreciated.

Many thanks

Lizzie

You would have to create rasters for each of your barriers and add them to the existing terrain. And then use that new "terrain" to perform your viewshed analysis.

If you look through the link below, it gives you an overview of how to do this.
