Military Map of Northern Virgnia 1865

A dataset listing Virginia counties by population for 2024.

This map provides the location of both park amenities and trail networks for parks in and around Leesburg, Virginia. The parks vary in size, from the 1/2 acre Catoctin Skate Park to the 138 acre Ida Lee Park. They are all open to the public from dawn to dusk. The amenity information shown was collected during a crowdsourcing effort between AOL staff and Loudoun County Office of Mapping & Geographic Information in May 2015 and individual Mapping & Geographic Information and Parks and Recreation staff in October 2015. Crowdsourcing involves groups of volunteers collecting data and information & was specifically undertaken on AOL's Monster Help Day, which is a world-wide event that encourages volenteerism. This was the third collaboration between AOL staff and Office of Mapping & Geographic Information to collect park amenity information in Loudoun County, which occurred in both early 2013 and 2014 on previous AOL Monster Help Days. The parks shown are administered by the Town of Leesburg, Loudoun County Parks and Recreation, and Northern Virginia Regional Park Authority.

The TIGER/Line shapefiles and related database files (.dbf) 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 shapefile 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 Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. The boundaries for counties and equivalent entities are as of January 1, 2017, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).

Trails within and around Fairfax County that are not maintained by Fairfax County. Contributors include: the National Park Service, Town of Herndon, Reston Association, City of Fairfax, Burke Center Conservancy, the Northern Virginia Regional Park Authority, and others.

This map provides the location of the original land grants within present day Loudoun County from the early 1700s to early 1800s. To view a list of sortable attributes of the information, please click on the Table button in the upper right corner of the map. For additional details, please visit here.

These are the original grantings of land within the Northern Neck Proprietary by Thomas, the 6th Lord of Fairfax and/or his agents until the mid 1780s during the settlement of Virginia. The map shows the approximate location of the original land grant as well as information on the grantee, the acreage of the grant (as calculated using the GIS), the year, and additional comments. The map is intended for historical reference only, as insufficient and incomplete original boundary surveys have resulted in potential inaccurate boundaries.

The original research for all of the land grants mapped in this application was completed by historian Wynne Saffer. They were originally mapped on USGS Quadrangles at a scale of 1:24000, then scanned to a digital file and the boundaries digitized by the Loudoun County Office of Mapping and Geographic Information staff.

The orginial land grant research is located at Thomas Balch Library. The land grants can be viewed on microfilm using the Record Number as a reference. This map is also located on the Office of Mapping and Geographic Information online map gallery, which can be found here.

A dataset listing Virginia cities by population for 2024.

As included in this EnviroAtlas dataset, the community level domestic water use is calculated using locally available water use data per capita in gallons of water per day (GPD), distributed dasymetrically, and summarized by census block group. Domestic water use, as defined in this case, is intended to represent residential indoor and outdoor water use (e.g., cooking, hygiene, landscaping, pools, etc.) for primary residences (i.e., excluding second homes and tourism rentals). Three reports were used with city- or water supply authority- level domestic water demand data, in addition to county level data. The 2011 Northern Virginia Regional Water Supply Plan provides detailed publicly, privately, and self supplied water use and population served for 2007 and covers most of the Virginia side of the EnviroAtlas study area. The 2011 Fauquier County Regional Water Supply Plan provides detailed publicly, privately, and self supplied water use and population served for 2007 and covers Fauquier County, Virginia. The 2010 Washington Metropolitan Area Water Supply Reliability Study, Part 1 from the Interstate Commission on the Potomac River Basin provides detailed publicly, privately, and self supplied water use and population served for 2008 by water supplier for suppliers drawing from the Potomac River. Data from these reports were weighted across publicly, privately, and self-supplied sources by population served, resulting in a single water use estimate between 25 and 204 GPD for each of the subregions in the study area. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

1:24,000 scale Geologic map of the State Line Peak Quadrangle, in Washoe County, Nevada, Map 82. Detailed geologic mapping by T. L. T. Grose in 1984. The State Line Peak quadrangle is located in a sparsely mapped region of the western part of the Basin and Range province several miles east of the Sierra Nevada state line. Within the quadrangle are parts of four physiographic features, the eastern part of the Fort Sage Mountains, the southern margin of the Honey Lake Basin, the western part of the Virginia Mountains and the northern end of Dry Valley. Geologic map includes description of 25 geologic units. The GIS work was in support of the U.S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. Previousely published geologic maps that encompass some of the area of the State Line Peak quadrangle include Bonham (1969) and Lydon and others (1960). Base map: U.S. Geological Survey State Line Peak 7.5-minute quadrangle, 1964.

description: The 2014 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The records in this file allow users to map the parts of the 114th Congressional Districts that overlap a particular county. Congressional Districts are the 435 areas from which people are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the States based on census population counts, each State is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a State as practicable. The 114th Congress is seated from January 2015 to 2017. The TIGER/Line shapefiles for the District of Columbia, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands) each contain a single record for the non-voting delegate district in these areas. The boundaries of all other congressional districts are provided to the Census Bureau through the Redistricting Data Program (RDP). The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes.

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.

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 Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, and municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four States (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their States. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. 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).
