High resolution 6-inch aerial imagery are now available from TNRIS for Smith County, including Lake Palestine. Four local entities contributed funds to collect the new imagery.
Surdex Corp. was selected under the 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 for city engineering and planning, 9-1-1 database updates and general mapping, appraisal district valuations, infrastructure mapping, and other applications.
The new orthoimagery were acquired in early January 2016 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 the full leaf-out season. The difference between deciduous and evergreen vegetation species 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.
