Abstract Law Enforcement Locations Any location where sworn officers of a law enforcement agency are regularly based or stationed. Law Enforcement agencies "are publicly funded and employ at least one full-time or part-time sworn officer with general arrest powers". This is the definition used by the US Department of Justice - Bureau of Justice Statistics (DOJ-BJS) for their Law Enforcement Management and Administrative Statistics (LEMAS) survey. Although LEMAS only includes non Federal Agencies, this dataset includes locations for federal, state, local, and special jurisdiction law enforcement agencies. Law enforcement agencies include, but are not limited to, municipal police, county sheriffs, state police, school police, park police, railroad police, federal law enforcement agencies, departments within non law enforcement federal agencies charged with law enforcement (e.g., US Postal Inspectors), and cross jurisdictional authorities (e.g., Port Authority Police). In general, the requirements and training for becoming a sworn law enforcement officer are set by each state. Law Enforcement agencies themselves are not chartered or licensed by their state. County, city, and other government authorities within each state are usually empowered by their state law to setup or disband Law Enforcement agencies. Generally, sworn Law Enforcement officers must report which agency they are employed by to the state. Although TGS's intention is to only include locations associated with agencies that meet the above definition, TGS has discovered a few locations that are associated with agencies that are not publicly funded. TGS deleted these locations as we became aware of them, but some may still exist in this dataset. Personal homes, administrative offices, and temporary locations are intended to be excluded from this dataset; however, some personal homes of constables are included due to the fact that many constables work out of their homes. TGS has made a concerted effort to include all local police; county sheriffs; state police and/or highway patrol; Bureau of Indian Affairs; Bureau of Land Management; Bureau of Reclamation; U.S. Park Police; Bureau of Alcohol, Tobacco, Firearms, and Explosives; U.S. Marshals Service; U.S. Fish and Wildlife Service; National Park Service; U.S. Immigration and Customs Enforcement; and U.S. Customs and Border Protection. This dataset is comprised completely of license free data. FBI entities are intended to be excluded from this dataset, but a few may be included. The Law Enforcement dataset and the Correctional Institutions dataset were merged into one working file. TGS processed as one file and then separated for delivery purposes. With the merge of the Law Enforcement and the Correctional Institutions datasets, the NAICS Codes & Descriptions were assigned based on the facility's main function which was determined by the entity's name, facility type, web research, and state supplied data. In instances where the entity's primary function is both law enforcement and corrections, the NAICS Codes and Descriptions are assigned based on the dataset in which the record is located (i.e., a facility that serves as both a Sheriff's Office and as a jail is designated as [NAICSDESCR]="SHERIFFS' OFFICES (EXCEPT COURT FUNCTIONS ONLY)" in the Law Enforcement layer and as [NAICSDESCR]="JAILS (EXCEPT PRIVATE OPERATION OF)" in the Correctional Institutions layer). Records with "-DOD" appended to the end of the [NAME] value are located on a military base, as defined by the Defense Installation Spatial Data Infrastructure (DISDI) military installations and military range boundaries. "#" and "*" characters were automatically removed from standard fields that TGS populated. Double spaces were replaced by single spaces in these same fields. Text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. All diacritics (e.g., the German umlaut or the Spanish tilde) have been replaced with their closest equivalent English character to facilitate use with database systems that may not support diacritics. The currentness of this dataset is indicated by the [CONTDATE] field. Based on the values in this field, the oldest record dates from 12/12/2006 and the newest record dates from 10/16/2009
Purpose Homeland Security Use Cases: Use cases describe how the data may be used and help to define and clarify requirements. 1. An assessment of whether or not the total police capability in a given area is adequate. 2. A list of resources to draw upon in surrounding areas when local resources have temporarily been overwhelmed by a disaster - route analysis can help to determine those entities who are able to respond the quickest. 3. A resource for emergency management planning purposes. 4. A resource for catastrophe response to aid in the retrieval of equipment by outside responders in order to deal with the disaster. 5. A resource for situational awareness planning and response for federal government events.

Absolute Positional AccuracyThe geographic location of entities was verified to be correct relative to the street vendor and version indicated by the [ST_VENDOR] and [ST_VERSION] fields. The horizontal accuracy is indicated by the [GEOPREC] field. A value of "BLOCKFACE" indicates the entity was geocoded on the correct street segment (block) and correct side of the street. A value of "ONENTITY" indicates that the location is on the entity's facility, as determined by USGS DOQQ imagery, and that it is on the correct street segment (block) and correct side of the street. Entities that are part of a larger institution (e.g., University Campus or Military Base) with "BLOCKFACE" precision may be located at the main entrance to the larger institution. Records with "-DOD" appended to the end of the [NAME] value are located on a military base, as defined by the Defense Installation Spatial Data Infrastructure (DISDI) military installations and military range boundaries.
Attribute AccuracyFor entities that were contacted, the name, address, city, state, and five (5) digit zip codes were verified to be correct as of the date indicated by the [CONTDATE] field. The existence of the entity was also verified, as well as whether or not it met the criteria for inclusion in this dataset. Four (4) digit zip code extensions were derived from USPS (United States Postal Service) data and were not verified. ID Check: The [ID] field is not blank and each of its values is unique. Coordinate Check: Coordinates are not null or zero and the [X] and [Y] fields match the shape. Basic Address Check: Physical addresses were verified to be non blank and to not be a "PO Box", "General Delivery", "Highway Contract", or "Rural Route" address. Highway Address without Type Check: Physical addresses containing the word "Highway" or "Route" were verified to also contain a type designator such as "State", "US", or "County", if one actually exists for the highway or route. These type designators are often missing from addresses, leading to confusion if more than one "Highway" of the given number exists in an area. Basic Name Check: Entity name is not blank, is not the same as entity city, and has a minimum of two (2) characters. Name does not contain punctuation characters that can interfere with database operations, such as " (quote) and * (asterisk). City Check: Entity's [CITY] field is not blank, and entity is located within 25 miles of its tabular city as found in the NAVTEQ Named Places reference file. State Check: The entity is located within its tabular state. County Check: The entity is located within its tabular county. FIPS Check: The tabular FIPS Code matches the entity's tabular county and tabular state. County in Name vs. Geographic Location Check: If an entity's [NAME] field contains the word "county" or "co", the same county value should also be in the entity's [COUNTY] field. Basic Phone Check: All phone numbers (including the area code) are ten (10) numeric digits. Alphabetic characters have been converted to the corresponding numeric digit. NPA_NXX Check: Area codes (sometimes called "Number Planning Areas", or NPA's) and central office codes (sometimes known as exchanges, or NXX's) were validated against data from the North American Number Planning Administration (NANPA). In some cases, NPA-NXX combinations did not show up in the NANPA data but were verified to work. Area Code Distance Check: The entity's area code (NPA) is valid, and the entity is not more than 25 miles from its area code boundary, as defined by data from the North American Number Planning Administration (NANPA), unless TGS has previously verified that the phone number rings to a headquarters location or otherwise does not ring to the entity's location. Zip Code Check: The entity's zip code is five (5) or nine (9) numeric digits, is listed in the postal database, is in the same state as indicated by the entity's [STATE] value, and is not a PO Box only zip code. Zip City Check: The entity's zip code and its city were verified to match according to the USPS Address Information System (AIS). Zip Code Distance Check: The entity is located within 25 miles of its zip code boundary, as defined by the U.S. Census Bureau's 1999 Zip Code file. NAICS Code Check: The NAICS field is not blank, the NAICS Code is one of the accepted codes for this layer, the NAICS Description is an acceptable Index Entry for the NAICS Code, and certain key words in the entity name do not conflict with the NAICS Code. Collocation Check: Entities with different addresses must not share the exact same geospatial location. Geographic Spell Check: Words that appear in the entity name were checked against a standard English word list (and Spanish word list for entities in Puerto Rico). Words not appearing in these standard word lists were then checked against names appearing in the Geographic Names Information System (GNIS) of geographic features that are located within 25 miles of the entity. Proper names were manually reviewed for correct spelling. Supplied Coordinates Distance Check: Entity is located within 3 miles of coordinates supplied by the original source.
Process Step1) The Correctional Institutions dataset and the Law Enforcement dataset were merged into one working file. TGS processed as one file and then separated for delivery purposes. 2) Entities were processed to determine or verify their name, physical address, city, state, five (5) digit zip code, phone number, and geospatial location. Entities that were contacted were also asked if they provided law enforcement services, correctional institution services, or both. Entities not located on military bases were contacted and asked to describe their location relative to landmarks in reference data (mainly streets) and features visible in ortho imagery. A phone number was not available for some entities, so their information was verified using other verbal contacts made through a telephone call. 3) Due to a request made by the Department of Defense, TGS made every effort to not contact military bases starting 03/27/2007 and ending 05/28/2008. During this time, entities located on military bases were verified through alternate resources, such as maps and ortho imagery. These records have not been contacted by TGS, and therefore, do not have directions. 4) All text fields were set to all upper case. 5) Leading and trailing spaces were trimmed from all text fields. 6) Non printable and diacritic characters were removed from all text fields.
SourceThe basic attribution (name, address, city, state, zip code, and telephone number) came from this dataset unless the entity was updated by TGS during Q208 processing.
