The geo-spatial data was primarily created from the conversion land surveying records and data. The data was created for internal use during the acquisition of additional Right of Way parcels and to aide in the location of the Right of Way during construction and maintenance. It was also created for the Public to be more completely informed how a project may impact their property or the area they live in. The descriptive or status data information for each parcel or tract of land is from the TxDOT Right of Way Information System database (ROWIS) and is updated daily at Midnight). Additions to the geo-spatial data are made on an ongoing basis and become available after one of the two daily updates.

This resource contains statewide networks of roadways, railroads, bridges, and low-water crossings, for Texas only.

Roadways detail: The Transportation Planning and Programming (TPP) Division of the Texas Department of Transportation (TxDOT) maintains a spatial dataset of roadway polylines for planning and asset inventory purposes, as well as for visualization and general mapping. M values are stored in the lines as DFOs (Distance From Origin), and provide the framework for managing roadway assets using linear referencing. This dataset covers the state of Texas and includes on-systems routes (those that TxDOT maintains), such as interstate highways, U.S. highways, state highways, and farm and ranch roads, as well as off-system routes, such as county roads and local streets. Date valid as of: 12/31/2014. Publish Date: 05/01/2015. Update Frequency: Quarterly.

Bridges detail: As with the roadways, both on-system and off-system bridges are maintained in separate datasets (54,844 total bridges, 36,007 on-system and 18,837 off-system). Bridges have numerous useful attributes, see coding guide [1] for documentation. One such attribute identifies structures that cross water: the second digit of Item 42 “Type of Service”. If the second digit is between 5 and 9 (inclusive) then the structure is over water. The bridges datasets are valid as of December 2016.

The roadways and bridges datasets contained here were obtained directly from TxDOT through personal correspondence. An additional transportation data resource is the Texas Natural Resources Information System (TNRIS) [3]. The railroads and low-water crossings were obtained through TNRIS.

November 2023 updates: in the years since this data archive was first published, TxDOT has developed an open data portal for downloading their roadway inventory and other datasets. Also, in 2023 TNRIS was renamed as the Texas Geographic Information Office (TxGIO). Their datahub [3] is continually evolving, but still has the tnris.org domain for now. We are not updating any of the basemap data in the contents list below, which was current at the time of Hurricane Harvey.

The TxDOT DCIS Projects service layer is a dataset of roadway construction and maintenance projects that are either currently under construction, or are in some phase of the planning process. Projects are grouped into 4 categories: projects that are currently underway or begins soon; projects in the construct authority (begins within the next four years); projects in the develop authority (planned to begin in 5 to 10 years); and projects in the initial phases of project development (corridor studies, construction in 10+ years). The dataset excludes non-letting projects. Update Frequency: 7 DaysSource: TxDOT Connect (TxC)Security Level: PublicOwned by TxDOT: TrueRelated LinksData Dictionary PDF [Generated 2025/05/21]

Historic Properties (Points, Lines). These include State Antiquities Landmarks (SAL), National Historic Landmarks (NHL), National Register of Historic Places Listed and National Register of Historic Places Eligible (NRHP) properties, Recorded Texas Historic Landmarks (RTHL), Texas Centennial Markers, and Contributing properties as well as locally designated resources if available. These features are compiled from various TxDOT and consultant surveys & reports. These determinations are made by the National Park Service or the State Historic Preservation Officer (SHPO). Historic Districts (Polygons). These include State Antiquities Landmarks (SAL), National Historic Landmarks (NHL), National Register of Historic Places Listed and National Register of Historic Places Eligible (NRHP) properties. Whenever possible, contributing properties and locally designated historic features have also been included. All of these features and their designations are gathered and determined by the National Park Service, the Texas Historical Commission, or through various surveys and reports performed by TxDOT and their consultants. Historic Bridges (Points). These are bridges listed or eligible to be listed on the National Register of Historic Places (NRHP). A bridge that is rare in type, unusual from an engineering perspective, or historically significant because of its location or association with an important event or person may be deemed a historic bridge. This determination is made by the TxDOT Environmental Affairs Division (ENV) in consultation with the State Historic Preservation Officer (SHPO). Texas has numerous examples of historic bridges, including metal truss bridges, concrete arch or span bridges, and suspension bridges. Historic Resource Survey Reports (Polygons). HRSRs are mapped for each project's Area of Potential Effect (APE). The APEs are determined by industry standards and/or survey requirements. These map elements are updated approximately once a month to reflect any changes. Bypassed Relocated Bridges (Points). Bridges that have been bypassed or relocated for one reason or another. Many now serve only as pedestrian crossings or exhibits at various local museums. Some bridges were relocated by TxDOT, some by county entities, and still others were handled privately. TxDOT project information is included if available.Update Frequency: Monthly Source: TxDOT Environmental Affairs Division Historic Properties DatabasesSecurity Level: Public

Vector polygon map data of city limits from across the State of Texas containing 2142 features.

City limits GIS (Geographic Information System) data provides valuable information about the boundaries of a city, which is crucial for various planning and decision-making processes. Urban planners and government officials use this data to understand the extent of their jurisdiction and to make informed decisions regarding zoning, land use, and infrastructure development within the city limits.

By overlaying city limits GIS data with other layers such as population density, land parcels, and environmental features, planners can analyze spatial patterns and identify areas for growth, conservation, or redevelopment. This data also aids in emergency management by defining the areas of responsibility for different emergency services, helping to streamline response efforts during crises..

This city limits data is available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

Functional classification is a federally-mandated categorization of roadways based on the level of traffic service and degree of access they provide. Updates to functional classifications are evaluated collaboratively by TPP, TxDOT districts, Metropolitan Planning Organizations and Federal Highway Administration (FHWA) staff and can occur on an as-needed basis as roadways are constructed and/or expanded. Technical corrections may also be made on an as needed basis as the GIS representation of our roadways is altered to reflect current conditions on the ground. As such, this layer is updated monthly to reflect the latest data from our Geospatial Roadway Inventory Database (GRID).Update Frequency: 1 MonthsSource: Geospatial Roadway Inventory Database (GRID)Security Level: PublicOwned by TxDOT: TrueRelated LinksData Dictionary PDF [Generated 2025/05/21]

A regional mobility authority boundary (RMA) is a political subdivision formed by one or more counties to finance, acquire, design, construct, operate, maintain, expand or extend transportation projects. These projects may be tolled or non-tolled. Counties forming an RMA do not have to be adjacent to one another. The service area of an RMA may overlap with another RMA (e.g. an individual county may form its own RMA and may also be part of another RMA). Fannin County was added to Sulphur River RMA as per Minute Order number 114957 dated June 29, 2017.Update Frequency: As NeededSource: Transportation Planning and Programming Division (TPP) | Data ManagementSecurity Level: PublicOwned by TxDOT: FalseRelated LinksData Dictionary PDF [Generated 2025/03/17]
