Satellite Imagery and Changes in Coral Reef Habitats

Satellite imagery is becoming increasingly utilised in an ever-growing range of applications, however some recent research has been brought to our attention which uses a range of satellite data to monitor changes in coral reef habitats in Bunaken, Indonesia.

This area is a hotspot for Indonesian biodiversity and thus monitoring changes here is vital, so that negative changes can be identified and prevented.

The study was conducted by a group of researchers from the Institute of Research Development (IRD) in France and used satellite imagery from different satellites, and of different time periods, to detect the changes over the period spanning 2001 to 2014. Imagery from the Worldview-2, IKONOS-2 and GeoEye-1 satellites was employed.

They classified the data into different coral reef types and by doing this over time, it can be used to see whether an area of coral reef changes throughout the time period. The results are ongoing, but appear a promising way to monitor shallow coral reefs over large areas, relative to analysing them from field visits on a boat.

The imagery available from these three satellite can be found on our online application, EarthImages, so please take a look as we have over 25 million satellite images available for you to order and download.
