Lake is one part of inland waters and plays an important role in human life and the surrounding environment. Lakes need to be preserved, especially in the lake area and its border. One way to preserve the lake is to map the potential of spatial information in the lake and its surroundings. Digital Terrain Model (DTM) and Digital Surface Model (DSM) can be used to obtain spatial information in the lake border. DTM and DSM can be extracted from terrestrial and non-terrestrial mapping such as remote sensing satellites. The study area in this study is Lake Oeduli on Rote Island. This study aims to inform the potential utilization of DSM and DTM for the spatial border of lakes. The potential is in the form of determining the lakeside line, lake border area, and vegetation height. All of these potentials can be extracted from DSM and DTM. This DSM and DTM can also be dynamic and non-dynamic. The results of this study can be utilized as a method for spatial information extraction of lake borders in support of national inland waters.
