THE USE OF REMOTE SENSING DATA IN TOPOGRAPHIC MAPPING SCALE 1: 25.000

摘要

Remote sensing data is the main data used in topographic mapping. The data used are interferometric synthetic aperture radar (IFSAR) Digital Surface Model with additional data for certain area such as Aster GDEM, SRTM and optical satellite imagery. In the 1:25,000 mapping using IFSAR data is 2003, while the optical satellite data ranging from 2010-2013. The main concern is the availability of data from remote sensing temporal resolution, spatial resolution, and how to use them. This is because there are problems in using both data-related differences in features associated with a difference in altitude information. In this paper described the use of remote sensing data in topographic mapping.
