Title: PSAP 911 Service Area Boundaries

Description:
Abstract: 911 Public Safety Answering Point (PSAP) service area boundaries in the United States According to the National Emergency Number Association (NENA), a Public Safety Answering Point (PSAP) is a facility equipped and staffed to receive 9-1-1 calls. The service area is the geographic area within which a 911 call placed using a landline is answered at the associated PSAP. This dataset only includes primary PSAPs. Secondary PSAPs, backup PSAPs, and wireless PSAPs have been excluded from this dataset. Primary PSAPs receive calls directly, whereas secondary PSAPs receive calls that have been transferred by a primary PSAP. Backup PSAPs provide service in cases where another PSAP is inoperable. Most military bases have their own emergency telephone systems. To connect to such a system from within a military base, it may be necessary to dial a number other than 9 1 1. Due to the sensitive nature of military installations, TGS did not actively research these systems. If civilian authorities in surrounding areas volunteered information about these systems, or if adding a military PSAP was necessary to fill a hole in civilian provided data, TGS included it in this dataset. Otherwise, military installations are depicted as being covered by one or more adjoining civilian emergency telephone systems. In some cases, areas are covered by more than one PSAP boundary. In these cases, any of the applicable PSAPs may take a 911 call. Where a specific call is routed may depend on how busy the applicable PSAPs are (i.e., load balancing), operational status (i.e., redundancy), or time of day / day of week. If an area does not have 911 service, TGS included that area in the dataset along with the address and phone number of their dispatch center. These are areas where someone must dial a 7 or 10 digit number to get emergency services. These records can be identified by a "Y" in the [NON911EMNO] field. This indicates that dialing 911 inside one of these areas does not connect one with emergency services. This dataset was constructed by gathering information about PSAPs from state level officials. In some cases, this was geospatial information; in other cases, it was tabular. This information was supplemented with a list of PSAPs from the Federal Communications Commission (FCC). Each PSAP was researched to verify its tabular information. In cases where the source data was not geospatial, each PSAP was researched to determine its service area in terms of existing boundaries (e.g., city and county boundaries). In some cases, existing boundaries had to be modified to reflect coverage areas (e.g., "entire county north of Country Road 30"). However, there may be cases where minor deviations from existing boundaries are not reflected in this dataset, such as the case where a particular PSAPs coverage area includes an entire county plus the homes and businesses along a road which is partly in another county. At the request of NGA, text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. At the request of NGA, 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.
Purpose: Homeland Security Use Cases: Use cases describe how the data may be used and help to define and clarify requirements. 1) A disaster has struck, or is predicted for, a locality. The PSAP that may be affected must be identified and verified to be operational. 2) In the event that the local PSAP is inoperable, adjacent PSAP locations could be identified and utilized.
Supplemental Information: If you are using this dataset as a shapefile, please be aware that it was converted from a Geodatabase. As a result, this shapefile may have attribution and metadata errors resulting from the conversion process. The following are known issues: null values may have been changed to 0s (zeros) or to blank values, numbers (including latitude and longitude) may have been rounded up or down, there may be issues with Unicode character strings, and time cannot be stored in a date field. Field names may have been truncated to no longer than 10 characters or completely changed, lengthy string attributes may have been truncated to 254 characters, and attribute columns may have been deleted. Shapefiles do not support coded domains and subtypes therefore the original file geodatabase attribution and metadata information for coded domains and subtypes could be incorrect or missing in the shapefile version. Please visit the following ESRI website for more information: caution-http://pro.arcgis.com/en/pro-app/tool-reference/appendices/geoprocessing-considerations-for-Shapefile-output.htm

Attribute Label: NAICSDESCR
Attribute Definition: NAICS (North American Industry Classification System) Description for entity. At the request of NGA, the "Index Entries" that appear on the NAICS webpage (http://www.census.gov/epcd/www/naics.html) are being used to populate this attribute as opposed to the "NAICS Title". While there is a one to one correspondence between NAICS Codes and "NAICS Titles", there is a one to many relationship between NAICS Codes and the "Index Entries". By using the "Index Entries", we have placed the entities that make up this layer into more specific categories; however, the user of this data should be aware that this was not the intended purpose of these "Index Entries". The "Index Entries" were intended as a way to search the NAICS database and as a way of enumerating ways in which establishments falling under the given NAICS Code may be named. Thus, there are often two or more "Index Entries" that are synonyms, for example: "Prisons" and "Penitentiaries". In cases like this, one of these synonyms was chosen and is now the standard "Index Entry" that TGS will use. If a specific "Index Entry" could not be determined for an entity, the NAICS title was used. For "Index Entries" truncated on the NAICS webpage (http://www.census.gov/epcd/www/naics.html), another website (http://www.naics.com) was referenced. NAICS descriptions (and NAICS codes) have been assigned based upon the entitys primary function, regardless of the function that qualified it to be included in this dataset. On the other hand, HSIP Themes are assigned based upon the function that qualified an entity for inclusion in this dataset. It is possible that if an entity appears in more than one dataset, it will have a different HSIP Theme in each dataset; however, it should have the same NAICS Code and NAICS Description in each case.
