Topics Covered in These Notes

The free GIS notes PDF includes detailed information on:

Concept of Digital Elevation Model (DEM): Learn about Digital Elevation Models (DEMs), which are 3D representations of a terrain’s surface, typically derived from terrain elevation data.

What is a DEM: Understand that DEMs are grid-based, numerical models that represent the elevation of the Earth's surface at specific points, enabling the analysis and visualization of topographical features.

Representation of DEM: Explore how DEMs are represented in a raster format, where each grid cell contains a value corresponding to the elevation at that point. This grid of elevation points forms the digital surface used in geographic and environmental analysis.

Sources of DEM Data: Learn that DEMs are generated from remote sensing technologies like satellite imagery, LiDAR, radar, and photogrammetry, providing high-resolution elevation data for various applications.

Applications of DEM: Discover how DEMs are used in applications like watershed analysis, flood modeling, terrain visualization, urban planning, and infrastructure development.
