SAV Home > 2009 SAV Report > Calculation of 2009 SAV Area

ArcInfo SAV coverages in a Universal Transverse Mercator (UTM) Zone 18 projection were used to calculate area in square meters for all SAV beds. These areas are summarized by USGS 7.5 minute quadrangle, Chesapeake Bay Program and Delmarva Peninsula coastal bay segments, and by zone in tables. Segment and zone totals were calculated using an overlay operation of segment and zone regions on the SAV beds.
