Coastal zone mapping and monitoring
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
