This feature class represents the smallest geographic unit located in development centers as defined by the Fairfax County Comprehensive Plan. The Comprehensive Plan text refers to these areas as land units, sub-units, districts, subareas, sub-blocks, and suburban neighborhoods, depending on what section of the Plan they are located. For the purpose of this feature class and metadata, these areas are referred to generically as a geographic unit.
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.

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.
