DEM — Digital Elevation Model

A Digital Elevation Model is a georeferenced raster grid where every pixel stores an elevation value, generated by processing overlapping drone photographs through photogrammetry software, or from classified LiDAR point clouds. Because it includes buildings, vegetation, and other surface features, a DEM captures the terrain the way it actually looks from above — not the bare ground underneath.

Trishunya delivers DEMs as GeoTIFF rasters that drop directly into GIS or CAD software, ready for slope analysis, flood inundation modelling, and cut/fill earthwork calculations. It's a foundational dataset for route planning on linear infrastructure projects and for drainage design on urban and solar sites, where accurate elevation data upstream saves rework downstream.
