Order Data

High resolution 6-inch 4-band (RGBIR) natural color and color infrared aerial orthoimagery are now available from TNRIS for Smith County, including the Lake Palestine area.

Four local entities and TNRIS/TWDB contributed funds to collect the new imagery.

  • City of Tyler
  • Smith County
  • Smith County 9-1-1 District
  • Smith County Appraisal District

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 2014 during leaf-off conditions. In leaf-off imagery, more on-the-ground features underneath deciduous tree cover are visible. Also, the distinction between deciduous and evergreen vegetation is evident with imagery acquired during the leaf-off period.
