This online interactive atlas is complimented by both a hard copy and e-copy. The Marine Atlas for the Tonga compiles over a hundred datasets from countless data providers and for the first time makes marine and coastal information accessible and usable as data layers and as raw data. The Tonga Marine Atlas was prepared by the Marine and Coastal Biodiversity Management in Pacific Island Countries (MACBIO) project

The Institute for Marine Remote Sensing (IMaRS) at the University of South Florida (USF) was funded by the Oceanography Program of the National Aeronautics and Space Administration (NASA) to provide an exhaustive worldwide inventory of coral reefs using high-resolution satellite imagery. By using a consistent dataset of high-resolution (30 meter) multispectral Landsat 7 images acquired between 1999 and 2002, USF characterized, mapped and estimated the extent of shallow coral reef ecosystems in the main coral reef provinces (Caribbean-Atlantic, Pacific, Indo-Pacific, Red Sea).
