Excerpt
Excerpt: NOAA?s National Geodetic Survey (NGS) is currently developing and testing a Shallow Water Positioning System (SWaPS). Primarily for coral reef, sea grass, and damage assessments, SWaPS provides precise (รณ 10 cm) horizontal positions for visible underwater features. The recorded imagery is entered into a Geographic Information System, where data can be viewed, archived, and monitored for secular changes. SWaPS provides research opportunities to quantify patterns of damage and recovery on shallow coastal habitats, including: The potential for surveying large areas rapidly without the need to deploy divers, The ability to return to specific locations within damaged areas without establishing permanent tags or markers, and -- The ability to survey an area remotely without specialized field personnel.
