Part 3: GIS and Spatial Analysis
The practical toolkit of overlays, rasters, terrain logic, and computational geography.
Textbook Part
GIS and Spatial Analysis
This part is where the book becomes recognisably GIS and spatial computation. It asks how locations become data, how vector and raster operations work, and how those operations become real analytical workflows.
How The Spatial Analysis Toolkit Fits Together
This part is easier to learn when the chapters read like a toolkit instead of an arbitrary list. The route starts with predicates and rasters, moves through vector operations, then builds up to terrain and monitoring workflows.
Predicates and Raster Basics
Learn how spatial relationships and cell grids represent geographic space.
- Point-in-polygon
- Raster resampling
- Map algebra
- Raster classification
Vector Analysis Toolkit
Turn geometry into queries about distance, overlap, and matching features.
- Buffers
- Overlay
- Spatial joins
Surface and Network Reasoning
Use elevation and friction surfaces to reason about visibility, flow, and movement.
- Viewsheds
- Least-cost paths
- Watersheds
Chapter Map
Vector Operations
Terrain Analysis
Least-cost path analysis continues this terrain toolkit in the topic-libraries volume.

These chapters are part of the topic-libraries volume, so they are intentionally not linked from the core-book build.
