Why Accuracy Matters in Coastal Surveys

Coastal environments are among the most dynamic on Earth. Tides, waves, currents, and episodic storms constantly reshape shorelines. When climate change amplifies these forces, thee rate of change can out pace traditional geodies cycles. Accurate geodes are not a luxury - they ary are a necessity for several reages:
