Remote Sensing Basics: Analyzing Vegetation and Earth Data

Satellite data is transforming how we monitor our planet, manage agriculture, and study environmental changes. Understanding how to access and interpret this data is a crucial skill for modern environmental analysis. This text-based course guides you through the fundamental principles of remote sensing, focusing on how to analyze vegetation health and land cover. You will transition from a complete beginner to confidently reading satellite bands, calculating key indices, and working with modern cloud-optimized geospatial data. What you'll learn: * Understand the core physical principles of electromagnetic radiation and satellite sensors. * Interpret multi-spectral imagery from modern open-source programs like Landsat and Sentinel. * Calculate and analyze key vegetation indices, including NDVI and NDWI, to assess plant health. * Explore modern spatial data formats, including Cloud-Optimized GeoTIFFs (COGs) and raster metadata. * Practice mapping land cover changes and interpreting vegetation anomalies through written step-by-step guides. * Apply basic geospatial workflows to identify environmental trends and prepare data for analysis. The course begins with essential terminology, the physics of light, and sensor basics, before moving into practical methodologies for processing and analyzing real-world environmental data. It is designed for absolute beginners, environmental science students, and curious analysts who want to start working with satellite imagery without any prior experience in remote sensing.
