"The Virginia Geographic Information Network (VGIN) acquired the Virginia Base Mapping Program (VBMP) aerial photography through funding provided by the E911 Services Board. The photography was captured in the spring 00 (during the leaf-off season). This is a statewide product. The aerial photography was initially captured at 1- or -foot resolution (contingent on local population density) in true color. In addition, some localities opted up for a 6-inch-resolution product. The data set provided on the DVD is a 1-meter resampled product. It is available in Virginia Lambert Conformal Conic (a customized projection developed by VDOT; see projection information in Appendix A). Note that areas associated with military bases and other points of national interest have been resampled at 5-meter resolution. The imagery is stored in tiles that measure ~3 miles on each side. Additional information on the VBMP aerial photography program and other VBMP data products available in www.vgin.virginia. gov/VBMP/VBMPHandbook_r2.pdfFor 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.pdf "

"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 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.

"Slope is a measurement of the incline, or the steepness, of a surface. Slope was derived from the TIN (see description under DTM on page 6 of the supplemental METADATA file). Slope was generated as a percent slope (which is the rise divided by the run multiplied by 100). The illustration to the right shows slope classifications and hydro (left side) and slope classifications with aerial photography and hydro. Slope layers are often used in site suitability analysis to support economic development, community planning or zoning, agricultural suitability analysis, precision agriculture, natural resource management, and water retention and surface water runoff modeling.The Virginia Geospatial Extension Program developed the slope layer using the TIN. It is suitable for general (regional) planning purposes and should be verified.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.
