This layer presents the counties of the state of Virginia. It provides detailed boundaries that are consistent with the tract, block group, and state data sets and are effective at regional and state levels.

1. US Census Bureau Cartographic Boundary File of county boundaries for the Commonwealth of Virginia.

From the US Census Bureau: "The cartographic boundary files are simplified representations of selected geographic areas from the Census Bureau’s MAF/TIGER geographic database. These boundary files are specifically designed for small scale thematic mapping."

The VA_TOWN dataset is a feature class component of the Virginia Administrative Boundaries dataset from the Virginia Geographic Information Network (VGIN). VA_COUNTY represents the best available city and county boundary information to VGIN.VGIN initially sought to develop an improved locality and town boundary dataset in late 2013, spurred by response of the Virginia Administrative Boundaries Workgroup community. The feature class initially started from the locality boundaries from the Census TIGER dataset for Virginia. VGIN solicited input from localities in Virginia through the Road Centerlines data submission process as well as through public forums such as the Virginia Administrative Boundaries Workgroup and VGIN listservs. Data received were analyzed and incorporated into the VA_COUNTY feature class where locality data were a superior representation of the city or county boundary.

Tax map polygons for Fairfax County, Virginia, USA as retrieved from the Fairfax County GIS website on 15 March 2011. Per communication with office staff, data on that page is in the public domain.

This service is Virginia data from the 2011 release of the Census Bureau TIGER/Line Shapefile for national counties or equivalent boundaries (tl_2011_us_county.shp)The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.The primary legal divisions of most States are termed counties. In Virginia, cities are independent of any county organization and thus constitute primary divisions. These incorporated places are known as independent cities and are treated as equivalent to counties for purposes of data presentation.The 2010 Census boundaries for counties and equivalent entities are as of January 1, 2010, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).

US Census Bureau Cartographic Boundary File of county boundaries for each state in the Unites States.

Vector polygon map data of property parcels from Roanoke County, Virginia containing 47,253 features.

Property parcel GIS map data consists of detailed information about individual land parcels, including their boundaries, ownership details, and geographic coordinates.

Property parcel data can be used to analyze and visualize land-related information for purposes such as real estate assessment, urban planning, or environmental management.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

Zipcode areas in Fairfax County, Virginia, USA as retrieved from this Fairfax County GIS website on 15 March 2011. Per communication with office staff data on that page is in the public domain.

These parcel boundaries represent legal descriptions of property ownership, as recorded in various public documents in the local jurisdiction. The boundaries are intended for cartographic use and spatial analysis only, and not for use as legal descriptions or property surveys. Tax parcel boundaries have not been edge-matched across municipal boundaries.

In September 2020, the Loudoun County Board of Supervisors directed staff to document telecommunication projects completed, in-progress, and future projects, using the 2014 Wireless GAP Analysis and the Segra Dark Fiber Area Network. Staff mapped the data identified by the Board, as well as other information related to telecommunication projects. This information was then used to identify select unserved or underserved geographic areas of the county.The companion interactive map allows the user to turn on or off all layers used in the project.

Critical minerals are essential for the energy transition; to meet sustainability goals, production of these resources must significantly increase within the coming decades. For example, demand for lithium, an element essential for battery technologies found in many electronics and vehicles, is anticipated to increase by more than ten-fold by 2050 compared to current production. Critical minerals occur in Amelia County, Virginia, however, considerable uncertainty remains regarding their location, amount, and types of commodities present. In fulfilling its mission to provide information on mineral resources of the national domain, the U.S. Geological Survey aims to synthesize and disseminate high quality data on mineral sites. Ensuring the accuracy of extracted information involves digitizing and georeferencing historic maps of the area that contain locations of mines and prospects. These maps, compared with records in the Mineral Resources Data System (MRDS; Schweitzer, 2019), were used to produce a harmonized dataset within Amelia County of reconciled, well-attributed mineral sites. Utilizing modern topographic mapping and LiDAR imagery, historical site locations were enhanced with increased accuracy to create a more accurate map of current and former mines and prospects in Amelia County. Data are presented in tabular form with complete bibliographic citations.

The Digital Geologic Map of the Culpeper East Quadrangle, Virginia is comprised of GIS data layers, two ancillary GIS tables, a Windows Help File with ancillary map text, figures and tables, GIS data layer and table FGDC metadata, ArcMap 9.1 layer (.LYR) files, and an ArcMap 9.1 map document (.MXD) file. The data were completed as a component of the Geologic Resources Evaluation (GRE) program, a National Park Service (NPS) Inventory and Monitoring (I&M) funded program that is administered by the NPS Geologic Resources Division (GRD). All GIS and ancillary tables were produced as per the NPS GRE Geology-GIS Geodatabase Data Model v. 1.3.1 (available at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.htm). The GIS data is available as an 9.1 personal geodatabase (cule_geology.mdb), as coverage and table export (.E00) files, and as a shapefile (.SHP) and DBASEIV (.DBF) table files. The GIS data projection is NAD83, UTM Zone 18N. That data is within the area of interest of Fredericksburg and Spotsylvania County Battlefields Memorial National Military Park.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.
