This book has been structured into six chapters. The first chapter, "Introduction to Remote Sensing," provides an overview of the fundamentals of remote sensing. It covers the definition, history of satellite systems, the electromagnetic spectrum, and resolutions, among other topics. The second chapter, "Aerial Remote Sensing," delves into the elements, interpretation, types of photos, and measurements related to aerial remote sensing. The third chapter, "Satellite Remote Sensing," focuses on the basics of satellite remote sensing. The fourth chapter, "Global Positioning System," discusses the GPS procedure, types, and developments related to the system. The fifth chapter, "Introduction to Geographic Information System," covers the basics of GIS. The sixth chapter, "Applications of Remote Sensing, Geographic Information System, and Global Positioning Systems," explores the various applications of these technologies. This book is a valuable resource for undergraduate and postgraduate students studying geography, as well as research scholars who wish to gain a better understanding of geospatial technologies.
