Career: Dtm
DTM stands for Digital Terrain Model. A DTM is a digital representation of the bare ground topography of the Earth's surface, with all objects like trees and buildings removed. DTMs are commonly used in geographic information systems (GIS), engineering, and environmental studies for tasks such as flood modeling, land development, and infrastructure planning. They are created using data collected from sources like aerial surveys, satellite imagery, and LiDAR. DTMs help professionals analyze surface features and make informed decisions in various projects.
