VGW Geospatial has provided the U.S. Army Corps of Engineers, Albuquerque District with surveying and photogrammetric services on two consecutive IDIQ contracts. Services have included photogrammetric mapping requiring acquisition of film and/or digital aerial photography, aerial triangulation, stereo mapping compilation, orthophotography, land use/land cover interpretation, creation of horizontal and vertical control networks, ground control for support of photogrammetric and LiDAR mapping, topographic mapping using total stations or GPS; detailed planimetric surveys; profile and cross section surveys, instrumentation surveys, cadastral surveys, site and utility surveys, and geographic information system (GIS) services.
Project accomplishments include:
· Cochiti Reservoir Historical Baseline Mapping – an award winning study to determine sediment deposition and distribution trends in the reservoir and upstream in the Rio Grande
· Comprehensive Evaluation of Project Datums Compliance Surveys – performing geodetic control and compliance surveys for 70 projects within New Mexico, Colorado, and Texas to establish a consistent basis of elevation at each USACE flood control project
· Las Conchas Post Fire LiDAR – providing data from the canyons to produce two-foot contour equivalent digital elevation data for geometry input to USACE hydraulic model programs for geomorphic and vegetation studies
· Holloman Airforce Base Taxiway Extension and Aircraft Parking Survey and Mapping – performing topographic and planimetric mapping including utility data, digital terrain models for engineering design for demolition plans, site plans, roadway plan and profiles, grading and drainage plans, and utility plans and profiles for construction
