LANDFIRE (LF) scientists use lidar data for canopy structure mapping. Incorporating lidar data into vegetation mapping methods has been promising, however, improvements are still being investigated.
The utility of lidar data for canopy structure mapping has been evaluated by LF scientists for some time. Algorithms were developed for mapping forest canopy height and forest canopy cover across the state of Alaska and were implemented in LF 2010. While LF used lidar extensively for LF 2016 Remap for all extents where available, LF is also investigating how to add more airborne lidar, as well as spaceborne data available from ICESat-2 and GEDI mission. The challenge for LF is to take advantage of the best available data while maintaining consistency of mapped products across the country. The methods being developed will continue to be refined as LF continues to provide annual updates.
