Semi-Automatic Extraction of Digital Surface Model from ASTER Imagery)

DEM derived from ASTER


Abstract

The development of photogrammetry techniques towards to digital systems is moving quickly along with the rapid advancement of computer technology. Similarly, the development of remote sensing technology provides many new innovations in relation to the mapping activities. One of them is marked by the launch of the satellite sensor ASTER EOS-AM1/Terra which has a special ability which is sensing the same place from two imaging positions within a single orbital path, to acquire stereo image pairs. From the stereo image pair, a three-dimensional model of the imaged surface area can be formed.

This study utilizes the principle of parallax to determine the elevation of points on ASTER imagery in the generation of a digital surface model. The determination of the elevation is considering two factors, namely the B / H ratio equal to 0.6 and different parallax for each pixel. To determine the corresponding points in two images, image-matching process is carried out automatically by cross correlation techniques. To perform automatic correlation and calculation of a digital surface model a computer program was developed using Delphi 5 programming language.

The main results obtained from this research is a georeferenced digital surface model of Parengan area, Tuban, East Java, with the size of 1132 pixels x 1131 pixels with a spatial resolution of 15 meters horizontally and 1 meter vertically. Based on 150 sample points taken from spot heights on the topographic maps, a root mean square error (RMSE) in elevation component of 8.8 meters or equivalent level of accuracy of 14.48 meters at the belief level of 90% is obtained, thus meeting the requirements accuracy according to the United States National Map Accuracy Standards for the purposes of making topographic maps with a scale of 1:100,000 or smaller.
