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. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

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.

Polygon feature representing the Virginia State Senate Districts within the City of Alexandria, Virginia. Provides location of the Virginia State Senate District boundaries within the City of Alexandria.

Provides the jurisdictional area of the City of Alexandria. Alexandria is approximately 15.3 square miles in size.

This line featured layer is used to build the Block-y layer which is a polygon layer that divides the parcels in the City of Alexandria Tax Maps into groups of parcels with a specified boundary

Geologic map of the Annandale quadrangle, Fairfax and Arlington Counties, and Alexandria City, Virginia. This map is available in paper format from the USGS, scale 1:24,000. For more information on this resource or to download the map PDF, please see the links provided.

Polygon feature representing actual zip code boundaries based on parcels for the City of Alexandria, Virginia. Provides specific zip code information based on parcels and used for analysis purposes.

Small Area plan polygons as determined by the planning department of the City of Alexandria. Small Area Plans are the 18 geographic planning areas within the City that together create the City Master Plan. These master plans are guiding documents that provide community-based long-range planning and analysis regarding the physical development and appearance of neighborhoods across the City. Overlay plans are Supplemental plans and amendments to existing Small Area Plans that provide greater standards or regulations. Properties located within the boundaries are subject to the requirements and regulations per the overlay plan in addition to other City standards and policies. If the overlay plan is silent to or does not address a specific issue or topic, the underlying Small Area Plan applies.

This is a polygon layer shows the boundaries that contain a planning area in the City of Alexandria that is names King Street Metro Planning Area. Planning and Zoning staff, as well as other agencies in the city government use this layer to identify the appropriate location of any developments within this planning area. This geographic area layer assists planning and zoning staff in approving applications and is managing compliance with all the conditions that are imposed on the businesses and developments within the K.S. Metro Planning District. This designated area King Street Metro Planning Area has specific boundaries that includes all the parcels that are to be considered when a developer requests a new subdivision or a re-subdivision of existing parcels. Certain restriction are attached to any existing and future developments.

The shape of urban settlements plays a fundamental role in their sustainable planning. Properly defining the boundaries of cities is challenging and remains an open problem in the science of cities. Here, we propose a worldwide model to define urban settlements beyond their administrative boundaries through a bottom-up approach that takes into account geographical biases intrinsically associated with most societies around the world, and reflected in their different regional growing dynamics. The generality of the model allows one to study the scaling laws of cities at all geographical levels: countries, continents and the entire world. Our definition of cities is robust and holds to one of the most famous results in social sciences: Zipf's law. According to our results, the largest cities in the world are not in line with what was recently reported by the United Nations. For example, we find that the largest city in the world is an agglomeration of several small settlements close to each other, connecting three large settlements: Alexandria, Cairo and Luxor. Our definition of cities opens the doors to the study of the economy of cities in a systematic way independently of arbitrary definitions that employ administrative boundaries.

Zoning_y layer is a polygon layer. Each polygon encompasses the zoning of all the parcels that are within the polygon boundary limits.
