"The digital topographic map is a United States Geological Survey (USGS) product. The original topographic maps for each county have been scanned and rectified (assigned coordinate information). The collars (the white margins along the sides of the map) have been removed. In addition, all topographic maps for a given county have been tiled together to provide seamless topographic coverage for each locality. The source scale of this product is 1: 4,000. It is available as a Mr. Sid (proprietary format that is “readable” by ArcGIS).For more information on this data refer to the supplemental metadata pdf found at: https://secure-archive.gis.vt.edu/gisdata/public/UnitedStates/Virginia/VCE_2002_metadata/METADATA.pdfThis data has been curated by the Virginia Cooperative Extension at Virginia Tech and Virginia Tech University Libraries. This data is meant for general use only. Virginia Tech’s University Library is acting as a steward for this data and any questions about its use should refer to our Terms of Use Page."

"The digital terrain model was initially generated by Center for Geospatial Technology (CGIT) for the Virginia Geographic Information Network (VGIN) using the mass points and break lines from the 00 VBMP aerial photography. This effort represents the most accurate digital terrain model (DTM) ever generated statewide for Virginia. The Triangulated Irregular Network (TIN) provides seamless coverage for each county in Virginia. TINs are used to ascertain landscape characteristics and to serve as a topographic model to support surface drapes (for imagery, etc.). Ancillary data sets are often generated from TINs. These data sets may include: slope, aspect, contours, digital elevation models, etc. Note that the DTM is appropriate for general planning purposes only.

"The National Resource Conservation Service (NRCS) captured these photographs through the National Agricultural Imagery Program (NAIP). Dates differ by county, but may be as recent as 2005. All the photographs are tiled together by county to produce this seamless 2-meter resolution product. The imagery was captured during the late spring/early summer (during the leaf-on seasons). The purpose of the NAIP is to provide imagery during the agricultural growing season so that the Farm Service Agency (FSA) can provide estimates of crops and acres under cultivation. Certainly, this product can be used for other applications as well.This product is available in a universal transverse Mercator (UTM) coordinate system. The NAIP imagery provided by the Geospatial Extension Program is either a near infrared (NIR) false-color composite or true color product. NIR imagery depicts healthy vegetation (high amounts of chlorophyll activity) in bright shades of red (note the fertilized lawns in the image below). This image is available as a Mr. Sid (proprietary format that is “readable” by ArcGIS or web browser plug-in). While a majority of Virginia localities have data, the imagery may not cover all portions of every county.

"The SSURGO soils data are the most accurate and comprehensive federal soils products available. The levels of soils data include:-SSURGO is the most detailed county-level data. -STATSGO is less detailed statewide map.-NATSGO is a very general soil map of the entire U.S. The SSURGO level of soil mapping is designed for use by landowners, townships, and counties for natural resource planning and management and regional applications. It is appropriate for watershed planning and some agricultural uses. The user should be knowledgeable about soils data and their characteristics. This database is scheduled to be completed for the entire country in 2008. Approximately 85 percent of all counties in Virginia have digital SSURGO soils data available. The Soils section located in the supplemental METADATA file includes an illustration that shows SSURGO soil data (left) and SSURGO soils data made “transparent” and superimposed over aerial photography (right). The SSURGO soil polygons associated with the Virginia County Data Series have been permanently joined with selected attributes. Not all attributes have been joined to the spatial data. These polygon files are disseminated as Shapefiles, and may be large in size (1 to 2 MB).
