This map of Utah's Southwest features a cartographic illustration created by draping four cross-blended hypsometric tint ramps over a grayscale hillshade. A hypsometric tint ramp is essentially a blend of one or more colors that is associated with an elevation range. A cross-blended hypsometric tint derived image consists of two or more color ramps with at least one ramp presenting the terrain in a "dry" condition and the other in a "moist" or vegetated condition. The addition of a satellite image derived vegetation index allows vegetation colors to appear where the terrain is vegetated irrespective of elevation.
