		abstract={DEM (Digital Elevation Model) is a form of digital representation of the height of the earth's surface. DEM is a system, model, method, and tool in collecting, processing, and presenting field information. This study aims to determine the elevation of the two measurement methods, namely terrestrial measurement (Total Station) and aerial photography (Drone), Terrestrial measurement is one of the total stations, total station is a modern electronic instrument used in conducting survey measurements that aim to measure angles, distances and altitude. An unmanned aircraft (english = Unmanned Aerial Vehicle or abbreviated UAV), is a flying machine that functions remotely by the pilot or is able to control itself with its own program. The research location is located on Jalan Poros Sungai Alam, Bengkalis District, Bengkalis Regency. And there is the highest point and the lowest point of the measurement location. The highest elevation for Total Station data is 1.017 at point 43. The lowest elevation for Drone data is 0.9699 at point 21. The highest elevation is for Drone data. drone data 49.9606. Lowest elevation for drone data 21.5819.}
