The lack of geographic and thematic maps of coral reefs has been identified by a number of agencies and academic panels as an obstacle in our understanding of reefs and our ability to assess change. The U.S. Geological Survey (USGS) has the capability to produce digital image maps useful for conducting unprecedented detailed mapping. Image maps covering the shallow near-shore coastal waters have been processed for several of the main Hawaiian Islands, including Hawai'i, Maui, Moloka'i, and O'ahu to enhance benthic cover information and to be used for several mapping and field survey investigations.
