*2.3.2 Mestoerrain units*

With available data of geologic formation or sediments at 1:50,000 scale, the computer algorism was used to identify and delineate the polygons with name attributes for example the metamorphic or moderately hard sedimentary rock, basalt, alluvium, and eolian sediments. By a rationale based on probability, the exposed bedrock units were identified by steeper slope classes, and the presence of rock outcrop as the mapping units.
