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
