Description
CHM rasters are created as a one metre cell size raster from LiDAR data, including the highest value in each cell from classes 3, 4 and 5 (low, medium and high vegetation). The absolute elevation raster was reduced by the DEM, before hydrological flattening avoiding aberrations due to vegetation overhanging water, to normalize the height above terrain and a background value of 0 enforced where there are no suitable LAS records within the cell.
