Gps Geodetic Data AdministratorPerforms development, maintenance, and refinements of ground GPS based structured geodetic control network, spatial grid reference system, and airborne GPS system for aerial photogrammetric data processing and adjustments. Determine the underlying geodetic vertical and horizontal control geospatial datum accuracy, and reliability; and develop specifications and procedures to accomplish required data standards. Perform sophisticated data processing and transformations and statistical analysis of ground and airborne GPS data using complex spatial data modeling including ‘on-the-fly’ solution techniques.
