Geographical Information Systems: Spatial Analysis and Databases

Ready to take your geographical data skills to the next level? Moving beyond basic map viewing is essential for solving complex spatial problems, analyzing environmental patterns, and managing large-scale geographic datasets. This text-based course guides you through the core theoretical concepts and practical applications of advanced geographical information systems (GIS). You will transition from simple map creation to performing structured spatial analysis and managing spatial databases. Through clear written explanations and step-by-step SQL and query examples, you will learn how to manipulate vector and raster data, work with coordinate reference systems, and solve real-world spatial problems. What you'll learn: Understand foundational spatial database concepts using PostGIS and PostgreSQL; Analyze vector and raster datasets to solve complex geographic queries; Manage coordinate reference systems and projections to ensure data accuracy; Apply spatial analysis techniques such as buffering, intersection, and network analysis; Structure geographic data using modern formats like GeoPackage and GeoJSON; Design structured spatial queries to filter and extract geographic insights. The course begins with essential terminology and the mathematical foundations of cartographic projections. You will then progress through structured modules covering spatial database design, query writing, and practical analysis workflows, ending with modern web-mapping data standards. This course is designed for learners who have a basic familiarity with GIS concepts and want to deepen their technical capabilities in spatial analysis and database management. No advanced programming experience is required. Start expanding your spatial analysis capabilities and master the backend of geographic information systems today.
