How do I specify the target-height in r.viewshed when using the operator through QGIS's processing toolbox? It doesn't seem to be available.
Who should I contact to adjust the interface such that the target-height option could be added to the r.viewshed dialogue box? Is that something that I can do myself?
In the mean-time, is the viewshed analysis plugin the only other option? It seems to routinely give me memory errors and crash, so I'd prefer to stay away from it.
