What You'll Learn

• Build accurate 3‑D models from overlapping 2‑D photographs using Structure‑from‑Motion techniques.
• Master the mathematics of parallax, stereoscopy, and the collinearity condition that drive photogrammetric reconstruction.
• Learn how to plan aerial surveys, set image overlap requirements, and calibrate digital cameras for optimal results.
• Understand the differences between aerial, close‑range, and satellite photogrammetry and when each is appropriate.
• Create Digital Surface Models (DSM), Digital Terrain Models (DTM), and Digital Elevation Models (DEM) for GIS analysis.
• Implement ground control points (GCPs) and spatial reference systems to improve positional accuracy.
• Analyze the photogrammetry pipeline—including feature detection, bundle block adjustment, and mesh generation—to produce high‑quality orthophotos.
• Apply photogrammetric concepts across industries such as surveying, civil engineering, architecture, archaeology, and environmental monitoring.
