Digital Elevation Models: Basic Concepts

Description

This lecture introduces basic concepts of Digital Elevation Models (DEMs) in Geographic Information Systems (GIS). It covers methods for sampling elevation, different techniques to measure elevation such as leveling, photogrammetry, and LiDAR, as well as the creation of DEMs. The lecture explains the importance of relief in spatial analysis, the properties of DEMs, and the representation of elevation through hillshade models and contour lines.
