Title
MDOT SHA Roadway Centerline [Maryland]
Description
Esri ArcGIS Online (AGOL) Hosted Feature Layer for accessing the MDOT SHA Roadway Centerline data product.MDOT SHA Roadway Centerline data consists of linear geometric features which represent the street centerline for roadways throughout the State of Maryland. The centerline represents the geographic location on the roadway between both shoulders (physical center), which often but not always coincides with the center painted line dividing bi-directional travel lanes. Roadway Centerline data plays an important role in transportation management and planning, while also being the basis for all other roadway-related data products.MDOT SHA Roadway Centerline data is the end product of a statewide data sharing process between the Federal Highway Administration (FHWA), Maryland Department of Transportation (MDOT), Maryland Department of Transportation State Highway Administration (MDOT SHA), county governments and local municipal governments. Using a common centerline allows for better exchange of information related to the roadway system and provides opportunities for more efficient collection of information about roadway assets. Some centerlines were created in-house using imagery, GPS data, and MDOT SHA's Highway Performance Monitoring System (HPMS) database and others were received from county governments and updated in house using imagery, GPS data and MDOT SHA's HPMS database. The Centerline data includes annual HPMS updates / improvements submitted to the Federal Highway Administration (FHWA).MDOT SHA Roadway Centerline data is needed for emergency response and management, routing buses and other vehicles, planning for land use and transportation needs, continuity of roadway data and display at county boundaries leading to the same "look and feel" across jurisdictions, tracking assets on and along the roadway network, producing maps at various scales, and numerous other applications. There are opportunities to make these processes more efficient, and this program addresses a shared foundation to solve some of these issues. This data is also used by various business units throughout MDOT, as well as many other Federal, State and local government agencies.MDOT SHA Roadway Centerline data is updated & published on an annual basis for the prior year. This data is for the year 2023.For more information about each attribute field, please review theMDOT SHA Roadway Centerline -Data DictionaryFor more information related to the data, contact MDOT SHA OPPE Data Services Division (DSD):Email:DSD@mdot.maryland.govFor more information, contact MDOT SHA OIT Enterprise Information Services:Email:GIS@mdot.maryland.gov
