Description: This data contains polygon features representing the soil classification areas from the 1990 soil survey for Fairfax County. Not all areas of Fairfax County were classified during this project so there areas that do not have soil information.
Description: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.
Description: Data set describes forest cover types in Fairfax County, as they pertain to gypsy moth managment. Data was created in-house by the Fairfax County Urban Forest Management, Forest Pest Program (Gypsy Moth Program)
Description: This layer was extracted from the 2011 land cover raster and converted to polygons. The polygons represent areas of tree canopy derived from classification of Worldview-2 satellite imagery. The layer can be used to show areas of tree canopy in maps and can serve as a basis for calculating areas of tree cover impacted by development.

Description: The Fairfax County tax map grid divides the county into approximately 444 tiles. This is the basis for the parcel numbering system in Fairfax County.
