AERIAL PHOTOGRAPHY, SURVEY AND MAPPING
October 25, 2001
The U.S. Bureau of Reclamation, Mid-Pacific region, is seeking a firm to perform aerial photography, surveying and mapping services in California, Nevada and Klamath Falls, Oregon. The contractor will provide services such as land surveying, ground control for the aerial mission, boundary resolution, subsidence documentation and dam monitoring. Aerial missions will be flown at various altitudes depending on accuracy and coverage requirements. Post-flight positives are aero-triangulated to augment the existing ground control and allow accurate mapping of large blocks and strips of photography. The aero-triangulated positives are used to create three dimensional, digital mapping files and include extracted digital terrain modeling, planimetric features and orthophotos.
