I've implemented a viewshed algorithm a while ago, by utilizing a modified
version of the algorithm published at

With this approach, it was crucial to provide a fast real-time option for
the viewshed calculation on relatively large raster DEMs by using only a
small memory footprint.

The implementation can be found here:


Does it make sense to spend some more effort and incorporate this approach
in GDAL officially?

Best regards,
