Mapping Coral Reef Benthos, Substrates, and Bathymetry, Using Compact Airborne Spectrographic Imager (CASI) Data

Mapping Coral Reef Bottom-types and Bathymetry Using Compact Airborne Spectrographic Imager (casi) Data

Airborne Lidar and Airborne Hyperspectral Imagery: a Fusion of Two Proven Sensors for Improved Hydrographic Surveying

Airborne hyperspectral imagery from the Compact Airborne Spectrographic Imager (CASI) has been proven to be a valuable tool for coastal measurements and analysis. CASI's spectral resolution of 288 bands for each spatial pixel allows for the extraction of a vast amount of information such as water clarity, water temperature, bottom type, bathymetry, as well as water quality (chlorophyll, dissolv...

Mapping of Sabah Islands using Airborne Hyperspectrometer

Human recreational activities and tourism are concentrated on the islands and in coastal waters, often depending on the maintenance of high water quality. The managing of impacts of urbanization and industrialization on the coastal zone ecology has become a high priority for many nations such as Malaysia and, hence, the need to develop better methods for monitoring and predicting change in isla...

Optimal scales to observe habitat dynamics: a coral reef example.

A new technique to estimate the characteristic length scales (CLSs) of real ecological systems provides an objective means to identify the optimal scale(s) of observation to best detect underlying dynamical trends. Application of the technique to natural systems has focused on identifying appropriate scales to measure the dynamics of species as descriptors of community and ecosystem dynamics. H...

Airborne Multispectral Remote Sensing of the January 1993 Shetlands Oil Spill

An aerial remote sensing campaign was mobilized at short notice, to obtain multispectral digital imagery over the MV Braer oil spill in the southern Shetland Islands during the week on January 13th, 1993. The Canadian company Borstad Associates Ltd. flew their Compact Airborne Spectrographic Imager (CASI) in a British aircraft under the direction of the National Rivers Authority. In spite of po...
