Sanborn Mapping and EDAW for the US Navy
White Shield supported Sanborn Mapping, EDAW, and the US Navy in providing aerial photo control for mapping to be used in identifying storm water alternatives for Ault Field in the Dugualla Lagoon, and Clover Lagoon areas of Whidbey Island Naval Air Station. White Shield established 40 photo control points within the wetland mitigation areas, 25 control points along the Ault Field drainage canal network, 11 control points in the surrounding Whidbey Island NAS area, and 8 permanent XYZ control points within the mitigation areas, using RTK GPS observations. White Shield also recorded invert elevation, pipe size, and construction type of storm drainage culverts along Crescent Harbor Road (mitigation area road frontage), and within the sewage treatment area. A subsequent effort included maintenance of 25 aerial panels from previous work. Additionally, White Shield provided services to establish ground control for hydraulic modeling of approximately 16 miles of the airfield drainage system. White Shield personnel provided cross-sections of drainage ditches at ±500-foot intervals, elevations on drainage structures, and soundings in Dugualla Lagoon.
