Theory & Foundations

Spatial overlay operations combine layers using set logic (AND, OR, NOT) to identify areas meeting multiple criteria.

This chapter provides comprehensive coverage of spatial analysis & geoprocessing techniques, methods, and best practices used in professional geospatial workflows.

Understanding these concepts is essential for intermediate-level analysts working with satellite data, field surveys, and spatial analysis projects.

Real-world applications span environmental monitoring, urban planning, disaster management, agriculture, and infrastructure development.
