Penentuan Kontur Tanah dengan Menggunakan Teknologi Global Positioning System dan Citra Satelit Aster di Desa Manggis, Karangasem, Bali

Abstract

program format Abstract: The contour map of land with large scale is very difficult to obtain, because the contour map in a particular area has not yet been created or owned, while planning must still proceed without having to wait for all the requirements to be met as there are some restrictions including time, cost, weather and terrestrial measurement equipment. In regional planning of Manggis village in Karangasem Regency, Bali, the contour map of the land based on a combination of Global Positioning System (GPS) data and Aster satellite imagery data can be used to make drainage planning, roads and tourism accommodation based on the environment. The process of digitizing satellite imagery uses Arc View GIS 3.3 software, namely a geographic information system program which is a special information system that manages data that has spatial information, so that the program can convert satellite imagery data into ground contour maps. Certain objects such as roads, houses, rice fields, gardens and others that were previously in raster format in a satellite image are converted becomes digital format, including: horizontal datum used, the suitability of element names according to the objects / elements being plotted, withdrawal lines in accordance with the appearance of the image. The land contour map produced in autocad program file will facilitate planners to create a master plan for the layout of natural tourism area in Manggis Village-Karangasem.
