Address Street Lines

Data Updated: July 27, 2026 This dataset contains address road segments from the Countywide Address Management System, a collaborative program between the County’s independent cities, Registrar/Recorder, Chief Information Officer, Public Works Department, Department of Regional Planning, and many others to manage addresses and street centerlines for the purposes of geocoding and cartography. More information about this layer can be found on the https://cams-lacounty.hub.arcgis.com/ What this data is (and isn’t) This dataset contains the best available information on Road Naming and includes address ranges, primary and secondary classification of roads within the County of Los Angeles. The dataset is NOT a NETWORK Dataset and does NOT support routing features. As well, the road features do NOT include information on turn restrictions, speed limits, etc. Description This dataset has been compiled from best available sources, including city databases, LA County Assessor parcels, and the County’s Road network maps. Please see the Source field for information. Street Name information has been split into multiple fields to support the County’s specifically designed geocoders – please see the entry on LA County Specific Locators and Matching rules for more information.数据更新日期：2026年7月27日 本数据集包含来自全县地址管理系统（Countywide Address Management System）的地址道路路段。该系统由本县各独立城市、登记员/记录员办公室、首席信息官、公共工程部、区域规划局等多方协作共建，旨在管理地址与街道中心线，以支撑地理编码与制图工作。 有关该图层的更多信息，请访问：https://cams-lacounty.hub.arcgis.com/ 本数据集的涵盖内容与非涵盖内容 本数据集收录洛杉矶县内当前最优的道路命名相关信息，包含地址区段以及道路的主次分级信息。 本数据集并非网络数据集（NETWORK Dataset），不支持路径规划功能；此外，道路要素未包含转弯限制、限速等相关信息。 数据集说明 本数据集整合自当前最优的各类数据源，包括各城市数据库、洛杉矶县评估员地块数据以及本县道路网络地图。相关数据源信息请参阅“来源（Source）”字段。 街道名称信息已拆分为多个字段，以适配本县专属设计的地理编码器——如需了解更多详情，请参阅洛杉矶县专属定位器与匹配规则相关条目。
