Adjusting Canopy Height for Slope

In this research paper the authors explain how they were able to take into account the effect of steep slopes on the canopy height models for forests. They note that, “On steep slopes, the raw elevation values located on either the downhill or the uphill part of a tree crown are height-normalized with parts of the digital terrain model that may be much lower or higher than the tree stem base, respectively. In treetop detection, a highest crown return located in the downhill part may prove to be a “false” local maximum that is distant from the true treetop.”

Sounds like a valuable read if you need to make these determinations.
