with high resolution aerial imaging

Miguel Castrence, Resource Mapping LLC

Overview• Coastal zone mapping & monitoring

• Aerial photography• Surveying & photogrammetry

• Advantages• Requirements • Challenges

• Applications• Invasive algae removal• Coral bleaching• Fisheries monitoring• Marine debris removal

Aerial photography• Wide area synoptic coverage• Planimetric (map-based) view at consistent ground

resolution• Manual interpretation of features at sub-decimeter

resolutions

Image acquisition• Spatial, spectral & temporal

resolutions (heterogeneous & dynamic environment with submerged features )

Image acquisition• Coverage: image overlap/sidelap• Budget

Image acquisition• Environmental considerations• Weather, haze, turbidity• Depth ranges, tides & swells• Wind speed & direction• Sun angle

• Logistics• Airspace restrictions
