The LiDAR data were converted to maps of top-of-canopy height (TCH). c A diverse array of satellite-based environmental maps were compiled to provide continuous geographic information on vegetation cover, topographic variables, and climate. d The satellite and LiDAR data were processed through a geostatistical model based on the Random Forest Machine Learning (RFML) approach to develop multi-island, statewide maps of TCH at 30 m spatial resolution. The statewide TCH map was converted to estimates of aboveground carbon density (ACD) using a universal plot-aggregate approach. The modeling process included an estimate of uncertainty on each 30 m grid cell for the entire State of Hawaii.
