Deep Acoustic Applications

Abstract

This chapter introduces visible and infrared remote sensing, specifically photographic, multispectral and hyperspectral imaging systems (Chaps. 2–4), and the situations in which they do and don’t work for mapping and monitoring coral reefs. Spectral dimensions of imaging sensors are explained, along with their fundamental control on the amount and type of information able to be mapped on coral reefs from airborne and satellite sensors. A specific set of coral reef biophysical environmental variables capable of being mapped by visible and infrared imaging systems is also defined. Examples are provided of image processing approaches that deliver science and management relevant data for monitoring coral reefs.
