ABSTRACT
The Photogrammetric Branch of NOAA now produces accurate base maps by combining the
technological advances of aerial photography, Global Positioning System (GPS), and Geographic
Information System (GIS). The combined technologies have enabled the production of a Florida
Keys National Marine Sanctuary GIS. This composed of approximately 3500 square nautical
miles of interconnected islands and benthic communities. Much of this area is being over-stressed
by commercial development and recreational activities. A description of this project will be
presented in its phases of operations: the initial field work, GPS assisted aerial photography and
aerotriangulation, digital compilation, and benthic classification. The GIS as a final product will
also be presented.
A futuristic look at the integration of other imagery sensors, such as Multispectral Scanners (MSS)
in the performance of mandated programs will be discussed. Anticipated applications of MSS and
photographic composite data sets include efficient inventory of wetlands, quick response for
natural disaster damage assessment, pollution tracking, submerged aquatic vegetation mapping,
and marine mammal studies. A marine resources GIS may play a central role in the production of
maps and digital data available for traditional nautical charting, the developing industry of
electronic charts and marine resource management.
KEY WORDS: Global positioning system, Photogrammetry, Geographic information system,
