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.
