Photogrammetry & 3D Reconstruction
Structure from Motion creates 3D models from overlapping photos captured by drones or aircraft.
Theory & Foundations
SfM reconstructs camera positions and 3D geometry from feature point correspondences across overlapping photographs.
This chapter provides comprehensive coverage of photogrammetry & 3d reconstruction 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.
