Aerial mapping system can protect threatened forests

University of Sydney archaeologist Damian Evans has developed a world-first aerial mapping system to identify tree species in dense forests surrounding the Angkor World Heritage site in Cambodia.

The technique combines VHR (very high-resolution) aerial images and laser scanning with botanical field data to create a detailed large-scale classification map of trees in dense tropical forest.

The aerial images can provide details of tree height, tree crowns and identify individual species. A research paper detailing the methods used has been published online in the open access journal PLOS One.
