 |
3001 acquired digital aerial photography using Leica ADS40 sensors to simultaneously collect color and color-infrared imagery for the U.S. Army Corps of Engineers (USACE) St. Louis/Jacksonville Districts under a contract to update existing orthophotography for the islands of Puerto Rico and the U.S. Virgin Islands (USVI). A host of government partners provided support to accomplish the mission, including primary partners U.S. Geological Survey (USGS), Puerto Rico Department of Natural and Environmental Resources (DNER), Department of Homeland Security (DHS), National Geospatial-Intelligence Agency (NGA) and the Lieutenant Governor’s Office of the USVI.
Imagery was collected over Puerto Rico and USVI from November 2006 through December 2007, resulting in multispectral data capture for the entire island of Puerto Rico and adjacent islands.

3001 has completed 4 of the 5 phases of the Louisiana statewide LiDAR project. The project so far has included 935 USGS quarter quadrangle maps, totaling more than 11,000 square miles (10% of US Coast). Following the control network surveys, RTK and continuous GPS surveys have been conducted at representative sites throughout the project areas. The sites are selected based on the various surface types including trees and brush, thick cut grass, scattered trees and grass, trees and grass, limestone, weeds and short grass, and gravel. As a quality control measure, a number of check-in points are surveyed along with the ground surface points. These check-in points consist of published horizontal and vertical control points within the project area. 3001 is producing 2' LiDAR-derived contours to support FEMA's National Flood Insurance Program through creation of Flood Insurance Rate Maps (FIRMs). To date, the project has worked with 3.5 million LiDAR points (xyz coordinates). LiDAR spot elevations falling within 1 m of the ground RTK survey profile data are extracted and a statistical comparison is conducted. This comparison derives statistics describing the vertical accuracy encompassing random and systematic errors. The LiDAR data (forecast value) and the RTK ground-truth data (observed value) are compared to compute the RMSE.
Services and Deliverables:
- Flight Survey Planning and Remote Sensing - LiDAR.

National Imagery & Mapping Agency (NIMA)/National Geospatial-Intelligence Agency (NGA), Nationwide City Map
3001 is providing "timely, relevant, and accurate geospatial intelligence" to support NGA's (formerly NIMA) mission under an omnibus contract called the Global Geospatial Initiative. 3001 is exploiting and analyzing imagery and generating geospatial information "to describe, assess, and visually depict physical features and geographically referenced activities on the Earth." 3001 is acquiring aerial photography and LiDAR data; generating digital orthophotography; processing LiDAR; collecting airborne GPS/IMU data; conducting GPS ground control surveys; creating DEMs, DTMs, and contours; performing photogrammetric (planimetric and topographic) mapping, stereocompilation, and feature extraction (3D building shapes, forest polygons, tree points, street centerlines, other transportation, and elevations/contours/ hydrography); developing geospatial data layers; performing attribution; and creating metadata. 3001 collected 0.3-meter and 1-meter imagery from several cities throughout the United States. Some of the cities include Jacksonville, FL, San Diego and San Bernardino, CA, and Nashville and Memphis, TN. The data support NGA's Homeland Security mission, comply with FGDC and USGS standards and specifications for The National Map, and conform to military specifications for 1:50,000/1:250,000 scale products, including Feature Foundation Data (FFD) work and Image City Maps (ICMs)/Digital Image City Maps (DICMs). 3001 also performed major kinematic profiles and horizontal and vertical control surveys of several thousand miles of transects on various continents to calibrate the Shuttle Radar Topographic Mission (STRM).
Services and Deliverables:
- GPS Ground Control Surveys and Airborne GPS.
- Aerial Photography & Digital Orthophotography.
- LiDAR Acquisition/Processing, DEMs, DTMs, and Contours.
- Aerotriangulation & Stereocompilation.
- Photogrammetric Mapping (Topographic & Planimetric).
- Data Conversion & Digital Mapping/Editing.
- GIS/RDBMS, Applications Development, & Metadata.
