Expansion of Texas Land Use/Land Cover through Class Crosswalking and Lidar Parameterization of Arboreal Vegetation
Popescu SC, Stukey J, Mutlu M, Zhao K, Sheridan R, Ku N. 2009. Expansion of Texas Land Use/Land Cover through Class Crosswalking and Lidar Parameterization of Arboreal Vegetation
The Expansion of Texas Land Use/Land Cover through Class Crosswalking and light detection and ranging (lidar) Parameterization of Arboreal Vegetation project was initiated by the Texas Commission on Environmental Quality to provide a more detailed and accurate map of land cover necessary for air quality modeling for the 12km Comprehensive Air Quality Model with Extensions (CAMx) domain. The project consisted of crosswalking classes from the LANDFIRE and Texas Parks and Wildlife Vegetation classes and classifying LandSat imagery to the Texas Land Classification System, and to derive forest composition characteristics with lidar for more accurate biogenic emission modeling. Lidar was used to estimate tree height, canopy base height, diameter at breast height, individual tree biomass, and canopy bulk density. Individual trees were identified through using lidar and the TreeVaw software, which uses a local maxima varying filter.
