TxDOT's 25 Districts are geographic subdivisions of the state, each responsible for planning, construction, and maintenance of on-system roadways within its administrative boundary. Each district is a conglomeration of several Texas counties. Area Engineer and Maintenance Section Offices are subdivisions of a district. This version utilizes a generalized boundary along the coast, which is sometimes necessary for analysis in which it is important to encompass segments of roadways that travel over water. Roadways on bridges or causeways that span intracoastal waterways are not covered by detailed polygons that precisely follow the coastline, therefore this generalized boundary layer is needed for some types of analysis where it is important to preserve such relationships.

This is a road lidar data collection for developing road elevation models and road inundation mapping methodologies, a joint work between ORNL and The University of Texas at Austin. This dataset is generated as part of the flood transportation infrastructure, partly funded by the NOAA CIROH project. ORNL is a project partner for high-performance computing-empowered flood inundation mapping methodology R&D. The dataset is computed using a GPU-accelerated lidar data processing workflow developed at ORNL. The lidar data source is from TxGIO, the state lidar data collection site. The output dataset is in two formats: laz and copc. It is organized by TxDOT's maintenance sections, covering the Austin District. Data size: 3.86 billion road lidar points, 1.67% of the entire lidar data input Projection: EPSG:32614 (WGS84/UTM zone 14N) Website: https://web.corral.tacc.utexas.edu/nfiedata/road3d/austin_district/AustinMaintenanceSections_H_epsg6343_V_epsg5703/ LICENSE FOR USE -- MAPS AND DATA DISCLAIMER This resource is shared under the Creative Commons Attribution CC BY, http://creativecommons.org/licenses/by/4.0/ MAPS AND DATA DISCLAIMER The Oak Ridge National Laboratory (ORNL) shall not be held liable for improper or incorrect use of the data described or information contained on this map or associated series of maps.

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]

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.
