A case study for Lake Mead (U.S.A) using Landsat satellite imagery data.
In this practical exercise, students will process multi-spectral satellite imagery data from Landsat missions to understand environmental changes over times (2000-2021). They will learn to process raster and vector data, and spatial analysis using the free and open-source GIS software QGIS. Tasks include the calculation of water surface areas in 2000 and 2021, where students are thereafter expected to dicuss reasons for why water surface areas are declining (climate changes? Or human activities?).
Suggestions for 3 lessons, 45 minutes each, suitable for students 15-18 years old.
