Description

If you're looking to explore GIS projects focused on elevation data, this course is the perfect place to start. Designed for beginners and intermediate learners, this course walks you through a variety of practical, project-based activities using Digital Elevation Models (DEMs). You'll work on real-world applications such as drainage and watershed management, slope and aspect analysis, and terrain-based surface modeling. Whether you're planning a hydrological study or just curious about the power of elevation data in GIS, this course will guide you step-by-step.

In addition to working with DEMs, you'll also get an introduction to LiDAR technology—one of the most accurate sources of elevation data. You'll learn how LiDAR is collected, processed, and used in terrain analysis. The course will also touch on remote sensing techniques related to elevation, giving you a broader understanding of how elevation plays a role in environmental and land-use studies.

By the end of this course, you’ll gain the confidence and skills needed to work with various elevation datasets, including SRTM, ASTER, and LiDAR-derived models. You'll be able to perform volume calculations, generate contour lines, and create 3D visualizations—making your GIS projects more accurate and visually impactful. Whether you’re a student, researcher, or GIS professional, this course will equip you with essential tools for elevation data processing in GIS.
