High resolution 6-inch aerial imagery are now available from TNRIS for Brazos County and portions of Burleson, Robertson, and Grimes counties. Six local entities contributed funds to collect the new imagery.
Surdex Corporation 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, appraisal district valuations, university facilities management, infrastructure mapping, and other applications.
The new orthoimagery were acquired in early January 2017 during leaf-off conditions. Leaf-off imagery allows the user to identify more on-the-ground features underneath deciduous tree cover than imagery acquired during full leaf-out. Further, the difference between deciduous and evergreen vegetation is easier to identify in imagery acquired during the leaf-off period.
The orthoimagery files (GeoTIFF, JPEG2000) are in the public domain. The JPEG2000s are available for direct download.
