This presentation details how height increments of spruce plantations vary in relation to two rasterized LiDAR-DEM derived indicators of soil wetness / drainage, i.e.,
- the cartographic Depth-to-Water index DTW, referring to the elevational rise away from nearest streams and other surface water bodies, and
- the Terrain Wetness Index TWI, referring to the logarithm of the upslope flow accumulation area over slope ratio at each raster pixel.
