High resolution 6-inch/12-inch aerial imagery are now available from TNRIS for two areas of interest commissioned by the San Antonio River Authority:
The San Antonio River Authority contributed funds to collect the new imagery as part of the 2015 Statewide Orthoimagery Project BUY-UP option to increase pixel resolution beyond 0.5-meter.
Surdex Corp. was selected under the legacy High Priority Imagery and Data Sets (HPIDS) state contract as the orthoimagery data provider. The TNRIS Strategic Mapping Program (StratMap) 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 by the San Antonio River Authority for engineering, general mapping, and other applications.
The new orthoimagery were acquired March 23-28, 2015 over Wilson, Karnes and Goliad Counties, and January 28-29, 2016 over Refugio and Aransas Counties during leaf-off conditions.
The orthoimagery files (GeoTIFF, JPEG2000) are in the public domain. The JPEG2000s are available for direct download.
