The Road Centreline dataset is depicted based on the Land Information System (“LIS”) 1:1000 Topographic dataset and is available as the Street Centre Lines feature class in the iB1000 dataset and Road Centreline in iRG1000 dataset. The usage of the LandsD’s Road Centreline is primarily focused on approximate location query and map annotation labelling. Archives of old Street Name datasets are available at (https://portal.csdi.gov.hk/csdi-webpage/achivedDatasetFileListPage/landsd_rcd_1648633077960_97785).

This layer shows the road centrelines in Hong Kong. It is a set of data made available by the Lands Department under the Government of Hong Kong Special Administrative Region (the "Government") at https://portal.csdi.gov.hk ("CSDI Portal"). The source data has been processed and converted into Esri File Geodatabase format and uploaded to Esri's ArcGIS Online platform for sharing and reference purpose. The objectives are to facilitate our Hong Kong ArcGIS Online users to use the data in a spatial ready format and save their data conversion effort.For details about the data, source format and terms of conditions of usage, please refer to the website of Hong Kong CSDI Portal at https://portal.csdi.gov.hk.

Road Centerlines represent the approximate centerline of a real-world roadway. The Road Centerlines GIS data layer utilizes arc-node topology with each road segment having attribute data associated with it that provides the segment’s street name, civic address ranges and jurisdictional place names on each side of the segment, and other attribute information.

This statewide dataset contains next generation 9-1-1 road centerlines for the State of Arizona, curated through the Arizona Department of Administrations (ADOA) Arizona 9-1-1 Program. The dataset is a vital resource for emergency services and public safety, providing accurate location information for emergency calls. The dataset includes geocoded address points and is a spatial dataset that can be used for various purposes such as analysis, mapping, and visualization. This dataset is a product of the ADOA Arizona 9-1-1 Program and is made available through ArcGIS Online.

The download hyperlink above also contains a full network topology for use with the Esri Network Analyst extension ** These street centerlines were developed for a myriad of uses including E-911, as a cartographic base, and for use in spatial analysis. This coverage should include all public and selected private roads within Lake County, Illinois. Roads are initially entered using recorded documents and then later adjusted using current aerial photography. This dataset should satisfy National Map Accuracy Standards for a 1:1200 product. These centerlines have been provided to the United States Census Bureau and were used to conflate the TIGER road features for Lake County. The Census Bureau evaluated these centerlines and, based on field survey of 109 intersections, determined that there is a 95% confidence level that the coordinate positions in the centerline dataset fall within 1.9 meters of their true ground position. The fields PRE_DIR, ST_NAME, ST_TYPE and SUF_DIR are formatted according to United States Postal Service standards. Update Frequency: This dataset is updated on a weekly basis.

This is the result of an initiative of the ACT Government, with support from Geoscience Australia, to create a 'single point of truth' road, track and trail data set for the ACT and its immediate region. Data was brought together from a range of existing custodians and combined to provide a single authoritative data set. The data was filtered and cleaned to select the best representation, both spatially and for the related attributes. The data set is maintained in the ACT Government's Corporate Geographic Database by these custodians according to agreed policy maintenance responsibilities. The data model in a hybrid of one developed by the ICSM Road Working Group adapted to meet specific needs of the ACT government. The entities include Transport_Line, Crossing_Point and Traffic_Control_Device_Point.

This map data layer represents the centerline of roadways for the City of Bloomington, Indiana. It includes source data from the City of Bloomington and Monroe County to create a countywide network. It includes public roads, named private roads, major multi-use trails, and proposed roadways to be constructed. Centerlines outside the City's mapped area may not be positioned accurately.

(Link to Metadata)(User Guide)(Symbology layer files: aotclass_only.lyr aotclass_surfacetyp.lyr)The Vermont Road Centerline data layer (TransRoad_RDS) contains all town and state highways, as well as many private roads. The centerlines were originally developed under contract by Greenhorne and O'Mara under the guidance of VCGI (1992). VCGI was the original steward of the road centerline data between 1992 and 2004. The Vermont Agency of Transportation (VTrans) is now considered the steward of this data layer. Updates have been performed over the years by VCGI, RPCs, and VTrans. The VT Agency of Transportation has taken over the update and maintenance of the road centerline data layer and has revised the layer to match "Official" highway mileage. NOTE: TransRoad_RDS meets the requirements articulated in the VGIS Road Centerline Data Standard (https://vcgi.vermont.gov/resources/standards).This layer is the most reliable source for official VTrans road class (AOTCLASS) information. However, this layer may not include every private road, and the road name information is not may not match perfectly with the EmergencyE911_RDS data layer. The EmergencyE911_RDS road centerline layer maintained by VT's E911 Board as the most up-to-date roadname information. It was originally based on TransRoad_RDS, and is therefore very similar. However, it includes all private roads and generally more reliable road name and address range information. There was a significant change in the schema in the June 2013 release as part of the effort between VTrans and E911 to merge their two datasets. The data layer includes the field structure agreed to by both entities, but most of the fields that are E911's have not been populated in this release.Stewards: Information Technology, Data Owner: Mapping Unit

Jackson County Road Centerlines are sourced from Emergency Communications of Southern Oregon (ECSO) road data and is updated regularly. This data shows only "current" roads within the County and is symbolized by Local Road Classification. This data is not a "surveyed" or "engineered" road centerline, but a digitized representation of the driving lane.

New Mexico Road Centerline Point data are an aggregated resource for road centerlines across the state. These data are contributed by local governments for NM911 Program purposes.

This dataset contains street centerlines for vehicular and foot traffic in Allegheny County. Street Centerlines are classified as Primary Road, Secondary Road, Unpaved Road, Limited Access Road, Connecting Road, Jeep Trail, Walkway, Stairway, Alleyway and Unknown. A Primary Road is a street paved with either concrete or asphalt that has two (2) or more lanes in each direction. A Secondary Road is a residential type hard surface road, or any hard surface road with only one (1) lane in each direction. An Unpaved Road is any road covered with packed dirt or gravel. A Limited Access Road is one that can only be accessed from a Connecting Road such as an Interstate Highway. A Connecting Road is a ramp connecting a Limited Access Road to a surface street. A Walkway is a paved or unpaved foot track that connects two (2) roads together. Walkways within College Campuses will also be shown. Recreational pedestrian trails and walkways through parks and wooded areas are not considered transportation and will not be digitized during this update. Walkways will not have an Edge of Pavement feature. A Stairway is a paved or wooden structure that connects two (2) roads together. Recreational pedestrian trails and walkways through parks and wooded areas are not considered transportation and will not be digitized during this update. An Alleyway is a road, usually narrower than a Secondary Road that runs between, but parallel to, two (2) Secondary Roads. Generally, Outbuildings will be adjacent to Alleyways. A Jeep Trail is a vehicular trail used for recreation. A Jeep Trail will not have an associated edge of pavement feature. A road coded as Unknown is a road, which in the judgment of the photogrammetrist, does not fall into any of the categories listed. Centerlines will be visually placed between the edges of pavement. One (1) centerline will be placed between each edge of pavement. Roads with medial strips, such as Limited Access Roads, will have two (2) centerlines for those portions of the road where the medial strip is present. For roads that terminate with a cul-de-sac, the centerline shall continue through the center of the cul-de-sac and stop at the edge of pavement. All attribute data will remain for all Street Centerlines that are not updated. For Street Centerlines that are new, the only attribute field that will be populated is the FeatureCode and UPDATE_YEAR. If a Street Centerline is graphically modified, the existing attribute data will remain and the UPDATE_YEAR will be set to 2004. The attribute values for 2004 Street Centerlines should be considered suspicious until verified. The ArcInfo Street Centerline coverage that is being updated has 800 segments of Paper Streets, 66 segments of Vacated Streets and 78 segments of Steps. Street Centerlines that are coded as Paper Streets in the OWNER field will remain unchanged in the updated dataset unless the area has been developed. In the event the area has been developed, the Street Centerlines will be modified to reflect the true condition of the visible roads. Street Centerlines that are coded as Vacated in the OWNER field will also remain unchanged in the updated dataset. In the event the area coinciding with the Vacated Streets has been developed, the Vacated Street Centerlines will be removed in order to reflect the true condition of the area. Street Centerlines that are coded as Steps in the OWNER field will be updated to reflect the current condition of the area. The Street Centerlines dataset consists of an external table that links to the supplied coverages and the Geodatabase created for this project using the "-ID" (UserID) field. In order to maintain the link to the external table and not loose valuable data the decision was made to keep all database information currently in the Street Centerline dataset. When a Street Centerline is modified during the update process, the field "UPDATE_YEAR" is set to 2004. All other database attributes will remain unchanged from the original values. All Street Centerline database data with an "UPDATE_YEAR" of 2004 should be verified before used. In some occasions the Street Centerline was divided into two (2) sections to allow for a new road intersection. Both sections of the resulting Street Centerline will have the same database attributes including Address Range. All new Street Centerlines will have zero (0) for "SystemID" and "UserID". This dataset was previously harvested from Allegheny County’s GIS data portal. The new authoritative source for this data is now the PASDA page (https://www.pasda.psu.edu/uci/DataSummary.aspx?dataset=1224), which includes links to historical versions of the shapefile representations of this data.

This dataset has been replaced by NZ Roads Subsections (Addressing) and will be deprecated on 31 May 2017. It is currently being ported from the new database in an effort to minimise disruption for customers. See NZ Roads Data Dictionary for field mappings to the new dataset.

This layer provides a feature representing Electoral road subsection (e.g. a city block) to which associated data such electoral addresses can be attached.

In Landonline a road name is commonly assigned to multiple stretches of roading such as between intersections with other roads. For this layer each of these individual road sections have their own geometry (as opposed to the Road Centre Line Layer where they have been aggregated).

A road may also have more than one road name, some road centreline geometries will duplicate other roads subsections even though there is in reality only one road formation. In addition, a road name is also commonly duplicated across the country e.g. "Queen Street", "High street" etc

The source Landonline data exists in order to provide linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

The road centrelines recorded in Landonline do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal.

As a general rule those that are not within a Road Parcels Layer should be treated as being of highly variable accuracy. They do however meet the purposes for which they have been captured, and can provide a valuable resource for other purposes provided that the user(s) understand their origin and consequential limitations.

Warning: The purpose of the location field is to enable differentiation between roads of the same name in the dataset. It should not be considered official nor part of a valid postal address. It can however be used as an indicative guide to location within a Territorial Authority, or in the case of regional road networks, as an indicative guide to location within New Zealand.

Road segments representing centerlines of all roadways or carriageways in a local government. Typically, this information is compiled from orthoimagery or other aerial photography sources. This representation of the road centerlines support address geocoding and mapping. It also serves as a source for public works and other agencies that are responsible for the active management of the road network.
