"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."

Dewberry collected LiDAR for ~3,942 square miles in various Virginia, West Virginia, and Maryland Counties. The acquisition was performed by Geodigital. This metadata covers the LiDAR produced for the Allegany County project area. The nominal pulse spacing for this project is 1.6 ft (0.5 meters). This project was collected with a sensor which collects intensity values for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to contract specifications: 1-Unclassified, 2-Ground, 7-Noise, 9-Water, 10-Ignored Ground due to breakline proximity, and 11-Withheld. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the 585 tiles (1500 m x 1500 m) that cover this deliverable.This is a MD iMAP hosted service.

"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.

This layer contains the boundaries of the 21 planning district commissions in Virginia and members of the Virginia Association of Planning District Commissions (VAPDC). Note that five counties have dual membership in two planning district commissions. Chesterfield County is shared by PlanRVA and Crater PDC; Gloucester County is shared by Hampton Roads PDC and Middle Peninsula PDC; Surry County is shared by Hampton Roads PDC and Crater PDC; Franklin County is shared by Roanoke Valley-Alleghany RC and West Piedmont PDC; and Charles City County is shared by Crater PDC and PlanRVA.
