PEMBUATAN DIGITAL ELEVATION MODEL (DEM) DENGAN KETELITIAN PIXEL (10 METER X 10 METER) SECARA MANUAL DI SUB-DAS RAWATAMTU
Abstract: This research aims
to create Digital Elevation Model (DEM) manually, presenting information DEM
Rawatamtu sub-watershed and evaluate DEM produced. A method of creating DEM
using software ArcGIS 10 with input data obtained from digitazion map in a
geocentric manner Indonesia (RBI) and survey the scorching tile with global
positioning system (GPS). DEM that has been created having spatial resolution
10 meters with a height 3032,44 m.dpl maximum and minimum 33,82 m.dpl.
Information from Rawatamtu subwatershed such as contour (showing the condition
of the surface of the land), slope (showing the level of the steepness of the
land), aspect (showing the direction of the slope), 3 dimensional display
(visualize land forms in 3D), and line of sight (determine the state of a place
can be seen from elsewhere). Based on the test results, DEM made manually with
spatial resolution 10 meters, the level of error is relatively small and could
describe characteristic of topography the watershed of more detailed.
