Three-dimensional (3D) land contour modeling using QGIS software on topography mapping in Buwit Village, Kediri District, Tabanan Regency, Bali

Abstract

A topographical map is a map that contains information about the elevation of the land surface in a place to the mean sea level (Mean Sea Level), which is depicted by contour lines. Information from the coordinates and elevation of detailed land points as a result of land surveying can be used to create a three-dimensional model of the land surface on the map using the Quantum Geographic Information System (QGIS) software application. With a three-dimensional (3D) model, the objects on the map are seen more alive as they actually are in the field, so that analyzing a topographic map can be done more easily. To support these activities, three-dimensional (3D) land contour modeling was carried out with QGIS software on topographical mapping in Buwit Village, Kediri District, Tabanan Regency, Bali.
