Catalog Last Checked From VDOT: 2021The purpose of including a catalog snapshot of geospatial datasets online by this agency in this description is to enable keywords by an end user of the VGIN AGOL search and provide that user to the authoritative source data page. If additional geospatial datasets beyond the listing above should be provided to end users from the authoritative source in a custom request, please contact VGIN at VBMP@vdem.virginia.gov to have them added to this listing.

The Marine Highways dataset was created on June 15, 2016 and was updated on June 16, 2025 by the U.S. Maritime Administration (MARAD) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). MARAD's Marine Highway Program is a Maritime Administration led program to expand the use of our Nation's navigable waterways to relieve landside congestion, reduce air emissions, and generate other public benefits by increasing the efficiency of the surface transportation system (https://www.maritime.dot.gov/grants/marine-highways/marine-highway). This dataset contains the locations of all 35 maritime routes that have been designated as Marine Highways by the Secretary of U.S. DOT. Routes included in this dataset are diagrammatic and may not depict all waterways and port connectors that are considered to be part of the U.S. Marine Highway System.

Represents public road centerlines in the state of Maine. Created by Maine Department of Transportation using MaineDOT's basemap linework managed in METRANS, MaineDOT's Linear Referencing System (LRS). MaineDOT_Public_Roads includes the most commonly-used attributes such as traffic volumes, federal functional classifications, jurisdiction, priority and more. This is updated regularly through a service, although the AGOL "Updated" date may only reflect the date this feature layer was created.Route and Road names: While MaineDOT's record of "Streetname" attribute is included and matches the official NG911 names whenever possible, the official road names are reflected in the NG911 (a.k.a. E911) data available from the Maine Geolibrary While multiple route designations (US Route 202, State Route 27, etc.) may be co-located on any given road, this dataset only shows the "primary" route.This dataset is designed for use in applications within MaineDOT.

The Massachusetts Department of Transportation Highway Division Road Inventory contains the spatial linework for all the public and a good portion of the private roadways in Massachusetts, along with roadway attributes covering the roadway classification, ownership, physical conditions, traffic volumes, pavement conditions, highway performance monitoring information, and more. This version has been processed by CTPS to eliminate overlaps among features in the original distributed by MassDOT and to add pavement data, which is no longer attached by MassDOT.

Department of Transportation (DOT) Scenic Land Strips contains parcels, generally long narrow strips of land, that were purchased by the DOT under the Federal Highway Beautification Act of 1965. The purpose of this program was to reduce the proliferation of billboards and other unsightly structures or facilities along federally designated highways. There are 33 parcels of land located along seven highways in eight towns.Highways and the corresponding towns where DOT Scenic Lands are located include:U. S. Route 44 in NorfolkInterstate 91 in MeridenInterstate 84 in PlainvilleInterstate 395 (formerly State Route 52) in KillinglyState Route 2 in GlastonburyState Route 8 in LitchfieldState Route 9 in Essex and Deep RiverThis does not include all land owned by DOT. The source map scale is unknown. No specific scale is recommended. This data should not be used for legal boundary purposes.See full Data Guide here.

These lidar data are processed Classified LAS 1.4 files, formatted to 2,117 individual 2500 ft x 2500 ft tiles; used to create Reflectance Images, 3D breaklines and hydro-flattened DEMs as necessary. Geographic Extent: Lake county, Illinois covering approximately 466 square miles. Dataset Description: WI Kenosha-Racine Counties and IL 4 County QL1 Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a derived nominal pulse spacing (NPS) of 1 point every 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (2011), State Plane, U.S Survey Feet and vertical datum of NAVD88 (GEOID12B), U.S. Survey Feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 2,117 individual 2500 ft x 2500 ft tiles, as tiled Reflectance Imagery, and as tiled bare earth DEMs; all tiled to the same 2500 ft x 2500 ft schema. Ground Conditions: Lidar was collected April-May 2017, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Ayers established a total of 66 ground control points that were used to calibrate the lidar to known ground locations established throughout the WI Kenosha-Racine Counties and IL 4 County QL1 project area. An additional 195 independent accuracy checkpoints, 116 in Bare Earth and Urban landcovers (116 NVA points), 79 in Tall Grass and Brushland/Low Trees categories (79 VVA points), were used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. Users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations. Acknowledgement of the U.S. Geological Survey would be appreciated for products derived from these data. These LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes Non-Vegetated Vertical Accuracy specifications.Link Source: Illinois Geospatial Data Clearinghouse

The Metropolitan Planning Organizations (MPO) dataset was compiled on July 07, 2025 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset contains the geographic boundaries of Metropolitan Planning Organizations. It provides users with transportation planning locations, sizes and names and is intended for metropolitan area multimodal transportation planning and programming.

The Virginia Geographic Information Network (VGIN) has coordinated and manages the development of a consistent, seamless, statewide digital road centerline file with address, road name, and state route number attribution, as part of the Virginia Base Mapping Program (VBMP). The Road Centerline Program (RCL) leverages the Commonwealth"s investment in the VBMP digital orthophotography and is focused on creating a single statewide, consistent digital road file.The RCL data layer is a dynamic dataset supported and maintained by Virginia"s Local Governments, VDOT, and VGIN. VBMP RCL is extracted and provided back to local governments and state agencies in many geographic data sets every quarter.GDB Version: ArcGIS Pro 3.3Additional Resources:Routable RCL With Network Dataset GDB(ArcGIS Pro 3.2)Shapefile DownloadREST EndpointRoad Centerline Data StandardArcGIS LYR FileHistorical RCL & Ancillary Centerlines -Contact VGIN
