FAQS on dem

Q: What does DEM stand for?

A: DEM stands for Digital Elevation Model. It is a digital representation of ground surface topography. DEMs exclusively represent bare earth elevations without features like buildings or vegetation.

Q: How is a Digital Elevation Model (DEM) created?

A: DEMs are generated using remote sensing techniques like aerial photography, LiDAR, or satellite imagery. Survey data is processed using photogrammetry software to create elevation points. These points form a continuous terrain surface model stored in grid formats.

Q: What are common uses of DEM data?

A: DEMs are fundamental for terrain analysis in hydrology, flood modeling, and geological studies. They support infrastructure planning for roads, pipelines, and construction projects. Additionally, DEMs enable 3D visualizations, landform classification, and environmental impact assessments.

Q: How does a DEM differ from a Digital Surface Model (DSM)?

A: DEMs represent ground elevation, excluding surface objects. DSMs include all terrain features like buildings and trees, capturing the "first surface" encountered by sensors. DEMs are derived by removing artificial/natural objects from DSMs for terrain-specific analysis.

Q: What formats are used for Digital Elevation Model data?

A: Common formats include GeoTIFF for raster data and ASCII GRID for simple elevation matrices. Specialized formats like USGS DEM and proprietary formats (e.g., DTED) are used in government/military contexts. Point cloud formats store raw elevation measurements for processing.
