Utah Address Points

The Address Points dataset shows Utah address points for all twenty-nine Utah counties. An address point represents a geographic location that has been assigned a US Postal Service (USPS) address by the local address authority (i.e., county or municipality) but does not necessarily receive mail. Address points may include several pieces of information about the structure or location that’s being mapped, such as: the full address (i.e., the USPS mailing address, if the address is for a physical location [rather than a PO box]); the landmark name; whether the location is a building; the type of unit; the city and ZIP code; unique code identifiers of the specific geographic location, including the Federal Information Processing Standard Publication (FIPS) county code and the US National Grid (USNG) spatial address; the address source; and the date that the address point was loaded into the map layer. This dataset is mapping grade; it is a framework layer that receives regular updates. As with all our datasets, the Utah Geospatial Resource Center (UGRC) works to ensure the quality and accuracy of our data to the best of our abilities. Maintaining the dataset is now an ongoing effort between UGRC, counties, and municipalities. Specifically, UGRC works with each county or municipality’s Master Address List (MAL) authority to continually improve the address point data. Counties have been placed on an update schedule depending on the rate of new development and change within them. Populous counties, such as Weber, Davis, Salt Lake, Utah, and Washington, are more complete and are updated monthly, while rural or less populous counties may be updated quarterly or every six months. The information in the Address Points dataset was originally compiled by Utah counties and municipalities and was aggregated by UGRC for the MAL grant initiative in 2012. The purpose of this initiative was to make sure that all state entities were using the same verified, accurate county and municipal address information. Since 2012, more data has been added to the Address Points GIS data and is used for geocoding, 911 response, and analysis and planning purposes. The Address Point data is also used as reference data for the api.mapserv.utah.gov geocoding endpoint, and you can find the address points in many web mapping applications. This dataset is updated monthly and can also be found at: https://gis.utah.gov/data/location/address-data/.

地址点（Address Points）数据集涵盖犹他州全部29个县的地址点信息。
地址点指由地方地址主管部门（即县或市政当局）分配了美国邮政服务（US Postal Service, USPS）地址的地理位置，但该位置未必可接收邮件。地址点可包含待映射建筑或位置的多项属性信息，例如：完整地址（若该地址对应实体物理位置而非邮政信箱，则为USPS邮寄地址）、地标名称、该位置是否为建筑物、单元类型、城市与邮政编码、特定地理位置的唯一代码标识符（含联邦信息处理标准出版物（Federal Information Processing Standard Publication, FIPS）县代码以及美国国家网格（US National Grid, USNG）空间地址）、地址来源，以及地址点加载至地图图层的日期。
本数据集为测绘级数据，属于定期更新的基础框架图层。
犹他州地理空间资源中心（Utah Geospatial Resource Center, UGRC）如同所有数据集的运维方一样，竭尽所能保障数据的质量与准确性。目前，数据集的维护工作由UGRC、各县级及市政部门协同开展。具体而言，UGRC与各县级或市政当局的主地址列表（Master Address List, MAL）主管部门合作，持续优化地址点数据。各县级单位的更新周期根据辖区内新开发与变更频率制定：人口稠密的县（如韦伯县、戴维斯县、盐湖县、犹他县及华盛顿县）数据更为完整，更新频率为每月一次；而农村或人口较少的县则每季度或每半年更新一次。
地址点数据集的原始信息由犹他州各县级及市政部门编纂，并于2012年由UGRC为MAL资助项目完成聚合。该项目的初衷是确保全州所有机构均使用经过验证的统一、准确的县级及市政地址信息。自2012年起，地址点地理信息系统（GIS）数据持续新增内容，目前已应用于地理编码、911应急响应以及分析与规划场景。地址点数据还作为参考数据，用于api.mapserv.utah.gov地理编码接口，同时众多网络地图应用中均可获取地址点信息。
