Introduction to Remote Sensing: Principles and Applications

Remote sensing is transforming how we monitor our planet, from tracking climate change to optimizing agricultural yields. Understanding the underlying science and physics of satellite imagery is the essential first step to working with geospatial data. In this text-based course, you will build a solid theoretical foundation in remote sensing. You will transition from knowing nothing about satellite data to confidently interpreting electromagnetic radiation, sensor types, and image processing workflows. What you'll learn: - Understand the physics of electromagnetic radiation and how it interacts with Earth's surface features. - Explore different sensor technologies, including optical, thermal, and active radar systems. - Analyze the differences between spatial, spectral, temporal, and radiometric resolutions. - Study the processes of image pre-processing, atmospheric correction, and enhancement. - Learn how remote sensing is applied in modern agriculture, forestry, disaster management, and urban planning. - Discover modern trends in satellite data, including open-access constellations and cloud-based analysis concepts. This course begins with the absolute basics of wave theory and orbital mechanics before guiding you through sensor types, data acquisition, and modern environmental applications through clear written explanations and conceptual exercises. It is designed for absolute beginners in geography, environmental science, or data analysis, with no prior physics or programming background required.
