Continental Mapping Projects - USACE Pine Creek

  1. 1. USACE Tulsa District Boundary Survey LOCATION: Pine Creek Lake, Oklahoma YEAR COMPLETED: 2011 OBJECTIVE: High-accuracy mapping to support dam expansion KEY POINTS: • Complex topographic survey from aerial photogrammetry & land survey • Supported complex planning efforts for dam expansion • Delivered 90 days from receiving task order CONTINENTAL MAPPING Mapping from Earth, Sky and Space www.continentalmapping.com Madison, Wisconsin Indianapolis, Indiana Kansas City, Kansas St. Louis, Missouri Pine Creek Dam was constructed in 1969 with the primary purposes of controlling problematic flooding, providing drinking water, and providing recreation. Today Pine Creek is the site of an important retrofitting proj-ect. The Federal Energy Regulatory Commission issued a license (No. 12646) to the city of Broken Bow, Oklahoma to add hydro power to this dam’s purposes. This work couldn’t start until USACE completes dam safety construction. Continental Mapping provided high-accuracy mapping of the Pine Creek dam, through our IDIQ master contract with the USACE Tulsa District. This area was approximately 620 acres and the data was used to sup-port development of a GIS suite with parcel mapping, land use, flood-plain, and wetland delineation. Aerial imagery was collected using 4 band, color, and direct digital imagery across the project site and required twenty-six photo control points. Continental Mapping provided the District with topographic and planimetric mapping, 1’ contours, and digital orthorectified imagery with 6” resolution. Planimetric mapping included curbs, paved and unpaved road, drives, sidewalks, buildings, manholes, catch basins, other visible utilities, poles, fences, vegetation, hydrology, and miscellaneous features visible in the imagery. The DTM supported a surface that met or exceeded ASPRS Class 1 accuracies.
