Description: The 1998 Chesapeake Bay SAV Coverage was mapped from 1:24,000 black and white aerial photography to access water quality in the Bay. Each area of SAV was traced on 1:24,000 USGS quadrangles and classified into one of four density classes by the percentage of cover. The SAV beds were then digitized into and ArcInfo GIS coverage using the quality control procedures documented below.

Description: This data set is a digital soil survey and is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was collected by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a county coverage format and include a detailed, field verified inventory of soils and nonsoil areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale maped. Also included is a special soil features layer (point and line features) that displays the location of features too small to delineate at the mapping scale, but that are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the Map Unit Interpretations Record relational data base, which gives the proportionate extent of the component soils and their properties.
