Coastal Features
Definition
Coastal Features are physical landforms and geological structures found along coastlines, such as beaches, cliffs, dunes, estuaries, and tidal flats. They result from the dynamic interaction of marine processes (waves, tides, currents) and terrestrial forces (sediment deposition, erosion, tectonic activity).
Application
Mapping coastal features in GIS is vital for marine spatial planning, habitat protection, climate adaptation, tourism development, and disaster risk reduction. Coastal feature data supports shoreline change monitoring, flood zone delineation, and policy development for sustainable coastal management.
FAQ
What are common coastal features tracked in GIS?
Common features include dunes, cliffs, beaches, wetlands, estuaries, inlets, and artificial structures like seawalls or jetties.
Why is mapping coastal features important?
It aids coastal hazard assessment, land-use zoning, habitat conservation, and shoreline protection initiatives.
How are coastal features detected and monitored?
Using satellite imagery, aerial photography, UAVs, bathymetric surveys, and field data collection.
Which professionals use coastal feature maps?
Marine biologists, coastal engineers, urban planners, and environmental regulators use these maps for analysis and planning.
