LRS2022 is a Linear Referencing System layer that includes interstate, U.S., state (VT), and other transportation routes logged by the Vermont Agency of Transportation. The routes in this layer represent the ETE route system, where ETE stands for End-to-End-Based route system, meaning that routes increment from start to finish within the state. The routes represent the full routes from beginning to end with no breaks for towns.Stewards: Information Technology, Data Owner: Mapping Unit

State Routes are depicted as lines with State Route identifiers and route measure attributes. All State Routes are included in this dataset. A directional indicator has been added to the RouteIdentifier to distinguish between the increasing and decreasing direction of mileposting. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov.

This feature class consists of approximately 195,000 features representing over 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS). Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. Multi-part geometry is created where routes are noncontiguous (e.g. a valid physical gap exists because another route is the master). The feature class only depicts master routes, those are routes built in the prime direction and on divided roadways where the non-prime direction is the master. Each road centerline record has a master route record assigned. Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions). Purpose: This linear referenced data layer represents roadways that are maintained by the Virginia Department of Transportation and provides the underlying spatially enabled geometric network to which all "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, etc...) can be located. Note: The overlap and non-prime measures are for reference only and have not been fully validated for accuracy or completeness.

This is a feature service - survey for counties, cities, and municipalities in Florida to provide details on their local GIS roadway data. This Survey is a resource for FDOT's Unified LRS project. The Unified LRS will include linework and data elements for ALL ROADS (state, county, and local) in the state of Florida and will incorporate centerline and lane mileage, traffic monitoring, roadway inventory, performance analysis, condition assessment, and travel speeds.The survey requests a range of information about the local data including collection method, update rate, geographic coverage, REST service link, and more. This survey is the primary method the Department is using to acquire local roadway data to incorporate into the Unified LRS.Additional resources and information for the Unified LRS can be found on the project's Hub site.For question or comments, you may contact FDOT-UnifiedLRS@dot.state.fl.us.

LRS2023 is a Linear Referencing System layer that includes Interstate, U.S., State (VT), and other transportation routes logged by the Vermont Agency of Transportation. The routes in this layer represent the town-based (TWN) route system, meaning that routes increment from start to finish within each town, resetting to zero at the town boundaries.Stewards: Information Technology, Data Owner: Mapping Unit

PCC Lines are shown by major branch lines. This data is used as 1) a linear referencing system (LRS); 2) for locating features on the PCC system by milepost value. PCC lines were built using existing data sources including railroad line track charts, track right-of-way maps, and recently digitized linework based off aeiral photos. In LRS, the locations of both data and events are determined according to their distance along a railroad line from some known point (e.g., the beginning of the line or line segment, a mile marker, a junction with another rail line, or a railroad crossing).

This data, also known as the Linear Highway Referencing System (LHRS), is used to locate events along the highway network. Three separate files make up the LHRS dataset: LHRS route is a spatial (GIS) representation of the highway network; LHRS Base Points divide the highway network into base sections with known driven distances; LHRS features points (composite listing) are additional described locations along the highway network. The location of events can be identified by a driven distance, along the LHRS route from a given LHRS Base point or feature point. *[GIS]: Geographic Information System *[LHRS]: Linear Highway Referencing System

The pathway representation consists of segments and intersection elements. A segment is a linear graphic element that represents a continuous physical travel path terminated by path end (dead end) or physical intersection with other travel paths. Segments have one street name, one address range and one set of segment characteristics. A segment may have none or multiple alias street names. Segment types included are Freeways, Highways, Streets, Alleys (named only), Railroads, Walkways, and Bike lanes. SNDSEG_PV is a linear feature class representing the SND Segment Feature, with attributes for Street name, Address Range, Alias Street name and segment Characteristics objects. Part of the Address Range and all of Street name objects are logically shared with the Discrete Address Point-Master Address File layer. Appropriate uses include: Cartography - Used to depict the City's transportation network location and connections, typically on smaller scaled maps or images where a single line representation is appropriate. Used to depict specific classifications of roadway use, also typically at smaller scales. Used to label transportation network feature names typically on larger scaled maps. Used to label address ranges with associated transportation network features typically on larger scaled maps. Geocode reference - Used as a source for derived reference data for address validation and theoretical address location Address Range data repository - This data store is the City's address range repository defining address ranges in association with transportation network features. Polygon boundary reference - Used to define various area boundaries is other feature classes where coincident with the transportation network. Does not contain polygon features. Address based extracts - Used to create flat-file extracts typically indexed by address with reference to business data typically associated with transportation network features. Thematic linear location reference - By providing unique, stable identifiers for each linear feature, thematic data is associated to specific transportation network features via these identifiers. Thematic intersection location reference - By providing unique, stable identifiers for each intersection feature, thematic data is associated to specific transportation network features via these identifiers. Network route tracing - Used as source for derived reference data used to determine point to point travel paths or determine optimal stop allocation along a travel path. Topological connections with segments - Used to provide a specific definition of location for each transportation network feature. Also provides a specific definition of connection between each transportation network feature. (defines where the streets are and the relationship between them ie. 4th Ave is west of 5th Ave and 4th Ave does intersect with Cherry St) Event location reference - Used as source for derived reference data used to locate event and linear referencing.Data source is TRANSPO.SNDSEG_PV.
