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