This file is a street centerline network in development by Los Angeles County to move toward a public domain street centerline and addess file. This dataset can be used for two purposes:Geocoding addresses in LA County \u2013 this file currently geocodes > 99.5% of the addresses in our test files (5,000 out of 8 million addresses) using the County\u2019s geocoding engines.This last statement is important \u2013 the County splits the street names and addresses differently than most geocoders. This means that you cannot just use this dataset with the standard ESRI geocoding (US Streets) engine. You can standardize the data to resolve this, and we will be publishing the related geocoding rules and engines along with instructions on how to use them, in the near future. Please review the data fields to understand this information.Mapping street centerlines in LA County This file should NOT be used for:Routing and network analysisJurisdiction and pavement managementHistory LA County has historically licensed the Thomas Brothers Street Centerline file, and over the past 10 years has made close to 50,000 changes to that file. In order to provide better opportunities for collaboration and sharing among government entities in LA County, we have embarked upon an ambitious project to leverage the 2010 TIGER roads file as provided by the Census Bureau and upgrade it to the same spatial and attribute accuracy as the current files we use. This effort is part of the Countywide Address Management System (click the link for details). Processes The County downloaded and evaluated the 2010 TIGER file (more information on that file, including download, is at this link). The evaluation showed that the TIGER road file was the best candidate to serve as a starting point for our transition. Since that time, the County is moving down a path toward a complete transition to an updated version of that file. Here are the steps that have been completed and are anticipated.Upgrade the geocoding accuracy to meet the current LA County street file licensed from Thomas Brothers. This has been completed by the Registrar/Recorder (RRCC) \u2013 matching rate have improved dramatically. COMPLETEDevelop a countywide street type code to reflect various street types we use. We have used various sources, including the Census CFCC and MTFCC codes to develop this coding. The final draft is here \u2013 Final Draft of Street Type Codes for CAMS (excel file)Update the street type information to support high-quality cartography. IN PROGRESS \u2013 we have completed an automated assignment for this, but RRCC will be manually checking all street segments in the County to confirm.Load this dataset into our currrent management
