Using Unmanned Aerial Systems for Forest Inventory Creation
Authors: Graydon Shevchenko, Andrea Sangster, Ian McDonald, Shaun Coghlan
This session discusses how I2S Ltd. used a UAV to take a series of images of a post-harvest area as part of a forest inventory project. The high resolution images were stitched into a single geo-referenced orthomosaic and digital surface model (DSM). A combination of software processes was used to extract individual tree locations within dense forest stands from the DSM. The inventory was used to calculate individual tree heights and enable the identification of tree species and restocked areas.
