Case Study Summary
• Possible to use UAV and photogrammetry to generate contours, high resolution imagery and compelling survey grade 3D models
• Products can be easily integrated into GIS or CAD software
• Photogrammetry is not the optimal method for terrain analysis under heavy canopy or surface objects
