GIS Programming Foundations is a practical guide to developing modern geospatial applications using Python. Designed for beginners and intermediate developers, this book introduces the core principles of Geographic Information Systems (GIS) from a programming perspective. You will learn how to work with spatial data formats, coordinate systems, and geospatial libraries while building real-world solutions. The book walks through automating GIS workflows, processing large datasets, and integrating mapping tools into custom applications. Key topics include spatial data structures, geoprocessing techniques, API integration, and scripting for automation. With a strong emphasis on hands-on learning, each chapter builds toward practical implementation, helping you gain confidence in writing efficient, maintainable GIS code. By the end of this book, you will be able to design and develop geospatial tools, streamline data pipelines, and create scalable GIS solutions using Python and modern development practices.
