Terrain model and gridding method variations for making topographic maps

Abstract

The purpose of research were: (1) exploring gridding method for making topographic maps, (2) inventing terrain model that producing from 3D data, (3) structuring standard operational procedure for making topographic maps, (4) producing topographic maps from terrestrial surveying data, digital terrain model, computer aided mapping and satellite imagery, (5) evaluating topographic maps which produced. The research is using descriptive method. Universitas Pendidikan Indonesia was research location. The research was conducted on September 2017 to December 2017. Geometric calculation is used to calculate abscissa, ordinate and height information, using spreadsheet. Topographic map which was producing contour line from digital terrain model software, satellite imagery from internet, line map from computer aided mapping software could be more accurate and effective than conventional and analog method.
