资源简介：
Chesapeake Bay SAV data were mapped from black and white aerial
photography, primarily at a scale of 1:24,000. Each area of SAV was
traced onto 1:24,000 USGS quadrangles and classified into one of four
density classes by the percentage of cover as determined from the
aerial photography. The SAV beds were then digitized into an Arc/Info
GIS coverage using documented quality control procedures.
The annual SAV aerial photographic monitoring program provides a
comprehensive and accurate measure of change in SAV relative abundance
that has been used to link improving water quality to increases in bay
living resources.
