High resolution 6-inch and 12-inch aerial imagery in 4-band natural color and infrared are now available from TNRIS for the Capital Area and Brazos County. Fifteen local entities contributed funds to collect the new imagery.

  • Brazos Central Appraisal District
  • Brazos County 9-1-1
  • Capital Area Emergency Communications District
  • City of Austin
  • City of Bastrop
  • City of Bee Cave
  • City of Bryan
  • City of Burnet
  • City of College Station
  • City of Round Rock
  • City of West Lake Hills
  • Hays County
  • Texas A&M University
  • Texas Municipal Power Agency
  • Travis County

Fugro USA Land was selected under the Strategic Mapping (StratMap) state contract as the orthoimagery data provider. The TNRIS StratMap Program administered the project providing coordination and project management services. TNRIS also performed QA/QC for the project which included inspection of interim and final orthoimagery products.

The new orthoimagery are used for city engineering and planning, emergency 9-1-1 routing, infrastructure mapping, and other applications.

The new orthoimagery were acquired in January 2019 during leaf-off conditions. Leaf-off imagery allows the user to identify on-the-ground features underneath deciduous tree cover than imagery acquired during full leaf-on time periods. Further, the difference between deciduous and evergreen vegetation is easier to identify in imagery acquired during the leaf-off period.

Data Access

The GeoTIFFs and JPEG2000 images are in the public domain. The JPEG2000s are available for direct download from the DataHub.
