BCEF {spNNGP}

Forest Canopy Height from NASA Goddard's LiDAR Hyperspectral and Thermal (G-LiHT) over Bonanza Creek Experimental Forest

Description

Forest canopy height (FCH) estimates from NASA Goddard's LiDAR Hyperspectral and Thermal (G-LiHT; Cook et al. 2013) Airborne Imager and percent tree cover (Hansen et al. 2013) over a subset of Bonanza Creek Experimental Forest, AK, collected in Summer 2014.

The BCEF matrix columns are longitude (x), latitude (y), forest canopy height (FCH) in meters from ground, and Landsat derived percent tree cover (PTC) for 188,717 observations. Longitude and latitude are in Albers Equal Area (proj4string "+proj=aea +lat_1=55 +lat_2=65 +lat_0=50 +lon_0=-154 +x_0=0 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=km +no_defs"). The last column (holdout) identifies a subset of data useful for assessing wall-to-wall predictive performance.
