SpletIn place of shaded relief, any raster map can be used including aspect or slope. The color raster map is usually an elevation raster map with colorful color table (as opposed to gray scale color table). However, any raster map can be used including categorical raster maps. The result is a raster map created from elevation and the shade raster. Splet04. maj 2015 · Slope-enhanced shaded relief methods clear out the gray shading in the low angle slopes, seen in traditional hillshade images, which cause undesirable effects when …

SpletShaded Relief function ArcGIS Pro 3.1 Other versions Help archive Overview A color 3D representation of the terrain is created by merging the images from the elevation-coded and hillshade methods. This function uses the altitude and azimuth properties to specify the sun's position. Notes Unit conversion SpletTPI (Topographic Position Index) is the difference between the value of a cell and the mean value of its 8 surrounding cells. Roughness is the difference between the maximum and the minimum value of a cell and its 8 surrounding cells. Such measures can also be computed with the focal function: f <- matrix (1, nrow=3, ncol=3) classic leather handle knives
