This layer contains the boundaries of special tax areas as defined by the taxing authority of Fairfax County. These are special tax districts where additional fees are levied on the properties within the districts.

This layer contains the buildings that have been captured through various processes. The original data in this layer was captured during the 1997 data conversion effort for Fairfax County. After that an update capture was completed in 2014 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery.

In between these planimetric update projects the GIS office has captured building footprints from orthophotography by performing heads up digitizing from site plans. These different sources of the buildings are indicated within the building attributes as well as the type of building. The buildings also include a building top and ground location and elevation value both in NAVD88 and NGVD29 datum. These locations indicate the highest point on a building based on the primary usable structure and the lowest elevation point of the structure. There are also buildings that may be multiple components that will make up a podium building. In this case there will be multiple polygons stacked on top of each other for a single building identifier. The difference of each polygon is the top elevation. This can be then used to extrude these structures to more approximate the look of these podium types of buildings.

The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos, it does not include a building top and ground location and elevation values.

Geographic boundary, portraying extent and limits of the jurisdiction recognized as Fairfax County, Commonwealth of Virginia. Defined in part by both physical features (Potomac and Occoquan Rivers), and monumented legal boundaries for surrounding jurisdictions (State of Maryland, Arlington, Loudoun, and Prince William Counties, cities of Alexandria and Falls Church).

This data is the source of all current parcel identification numbers and the approximate location of the parcel boundaries. These features were created through various means including conversion from mylar maps, heads up digitizing and coordinate geometry. The graphic depiction of the parcel boundaries in this layer is a derivative of the recorded documents that contain the official boundary of each parcel. To determine the accurate definition of any given parcel go to the recorded document housed in the official court recorded system, CPAN.

This layer contains cadastral information for Fairfax County, Virginia. This includes, but is not limited to the portrayal of polygonal features (such as parcels, subdivisions and easements), text (parcel numbers, street names and addresses), and symbols (parkland, schools, "double circles", etc.). This layer was initially developed as a digital copy of the ink-on-mylar property maps maintained by the County since the early 1960's.

Layer Name: GISMGR.PARCELS

This layer contains data defining the exterior boundaries of land under common ownership, typically within condominium properties within Fairfax County, Virginia. The common area layer was created to depict these areas of land that do not actually have parcel identification numbers. These areas of land are owned by a group of properties that lie within the common area. Information portrayed on this layer was initially derived from the ink-on-mylar property maps maintained by the County since the early 1960s.

Minor transportation contains the non-primary road polygons in Fairfax County. The original data in this layer was captured during the 1997 data conversion effort for Fairfax County. After that an update capture was completed in 2014 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery. The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos.

The data in this layer provides the areal extent of the paved and unpaved driveways, paved and unpaved shared driveways, paved and unpaved parking lots, and paved and unpaved private roads, up to the edge of pavement. Minor transportation features are features that exist outside of the right of way. These features will typically have a match line where they coincide with the major transportation features.
