Introduction to Geographic Information Systems (GIS)

Geographic Information Systems (GIS) drive decision-making in urban planning, environmental science, logistics, and resource management. Understanding how to work with spatial data is a highly sought-after skill across multiple industries. This text-only course guides you from absolute beginner to confidently understanding how geographic data is structured, analyzed, and presented. You will transition from a basic understanding of maps to analyzing spatial relationships and reading modern geographic datasets. By focusing on foundational concepts first, you will build a strong mental model of how coordinates, projections, and spatial databases function in the real world. What you'll learn: * Understand foundational GIS concepts, coordinate reference systems, and map projections * Differentiate between vector and raster data models and their appropriate use cases * Query spatial databases to extract meaningful geographic insights * Apply basic cartographic design principles to create clear and informative map layouts * Explore modern web-GIS concepts, cloud spatial databases, and collaborative mapping workflows * Analyze real-world spatial problems through structured, text-based practice scenarios This course starts with essential terminology and the history of spatial analysis before guiding you through data models, query languages, and modern web-based GIS applications. You will learn through clear explanations, practical scenarios, and structured exercises designed to reinforce your understanding. This course is designed for beginners, students, researchers, and professionals who have no prior experience with GIS or spatial analysis. No special software is required to start learning.
