There are many posts on the best parameters to get a DTM in heavily forested areas. In contrast, I am interested in getting the best possible DSM in these areas. There are papers on this topic that indicate it is possible but currently I am having poor results with multiple packages (including Socet Set, although we have just started using it).
Can anyone recommend a set of processing options that have worked for extraction of DSMs over forested areas? Regrettably we face the additional problem that these are conifer forests of varying stem density, which means we have some areas that have full coverage (which generally leads to more similar patterns from multiple azimuths) and also some small clumps of trees (which, due to displacement and local conditions, look very different from different angles)
