What is a Prison / Correctional Facility?
The Federal Bureau of Prisons website provides an authoritative list of federal prison facilities. Only Institutions, Private Facilities, and Correctional Complexes should be included -- not offices or training centers.
State Department of Corrections websites also list private and public prisons in each state.
Check out our Authoritative Sources List for more on the types of sources that are acceptable.
Where do I place a Prison / Correctional Facility structure point?
If a prison has a single large building, place the point at the center of the building. If the prison does not have a distinctive single building, then place the point at the center of the prison facility.
If a prison complex has more than one named facility, each with its own separate grounds or building, then place a prison point on each facility. For example, the Florence Federal Correctional Complex has three facilities (Florence Federal Correctional Institution, Florence High Security United States Penitentiary, and Florence Administrative Maximum United States Penitentiary), and therefore should be represented by three structure points. It may be difficult to determine from aerial imagery which facility is which, but you may be able to tell from Google Street View™, from an online facility map, or by examining a photo of the prison entrance (if it exists on the prison webpage) and comparing this to the building footprint in the satellite image. If it cannot be determined which facility is which, then place all facility points adjacent to each other near the centroid of the entire facility.

How do I name a Prison/Correctional Facility?
Use the name of the facility as it appears on the facility website. For federal prisons, the website uses several formats for names, but the format where the prison name comes last is preferred (e.g., United States Penitentiary Florence High).
