This course on GIS and Remote Sensing, designed for first-year Master's students in Hydrogeology, presents the fundamental concepts related to the management and analysis of geographic data. It covers the definition of GIS, its components, the coordinate systems used in Algeria, as well as vector and raster data types. Spatial analysis is emphasized, including buffers, intersections, and raster processing. A dedicated chapter introduces remote sensing, covering its physical principles, the main optical and radar sensors, and spectral indices applied to hydrogeology. Practical exercises are conducted using ArcGIS to develop skills directly applicable in water management institutions and consulting offices. The teaching relies on real case studies integrating various data sources (maps, GPS, satellite imagery). Special attention is given to accurate georeferencing, essential for reliable analyses. The overall objective is to enable students to effectively use geomatics for spatial analysis, modeling, and sustainable water resource management.
