Description

This course provides an in-depth exploration of soil salinity monitoring using MODIS satellite data and Google Earth Engine (GEE), tailored for professionals and researchers in remote sensing, agriculture, environmental science, and land management. Participants will gain a comprehensive understanding of remote sensing fundamentals, soil salinity dynamics, and advanced geospatial data processing techniques.The course begins with the core principles of remote sensing and soil salinity, emphasizing spectral characteristics and the significance of salinity in agricultural productivity and ecosystem health. Learners will then be introduced to Google Earth Engine, mastering its cloud-based platform to efficiently handle large satellite datasets. A detailed focus on MODIS datasets, including surface reflectance bands and temporal resolution, enables students to calculate soil salinity indices like the Normalized Difference Salinity Index (NDSI).Hands-on practical sessions guide students through clipping satellite imagery to specific regions, computing salinity indices, visualizing results, and exporting geospatial products in GeoTIFF format for further analysis. By the end of this course, participants will be equipped with the technical skills to conduct large-scale, temporal soil salinity assessments, crucial for sustainable land and water resource management.This course is ideal for environmental scientists, GIS professionals, agricultural specialists, and policy makers aiming to leverage remote sensing and cloud computing for precision agriculture and environmental monitoring. It empowers learners to apply satellite data analytics to real-world challenges, enhancing decision-making processes for soil health management and environmental conservation.
