The National Geodetic Survey (NGS) conducts fundamental research and development designed to integrate new imaging and mapping technologies into our production programs. We support the Remote Sensing Division of NGS, and focus on studies that are designed to increase efficiencies in the shoreline mapping and airport obstruction charting programs. We perform accuracy assessments by comparing results obtained with a new technology to those results obtained using conventional high accuracy photogrammetric techniques. Our strategy is to assemble multiple datasets at a number of sites throughout the United States. We have ongoing collaborations with partners in NOAA, other federal agencies, and academia.
  • Decrease the time interval from the identification of the program need to the delivery of the map products.
  • Gain flexibility over weather conditions.
  • Gain flexibility over tidal constraints.
  • Promote a multi-sensor, fusion-based operational approach in which NOS can supply multiple users with data from the same flight mission.
  • Quantify the geometric accuracy of the NOS Shoreline Manuscripts by conducting a forward error propagation and error analysis.
  • Investigate the use of high resolution Synthetic Aperture Radar for all weather operations and quantify the accuracy achieved.
  • Investigate the use of thermal infrared imagery for nighttime operations and quantify the accuracy achieved.
  • Investigate the use of Multi and Hyperspectral Systems for shoreline mapping and quantify the accuracy achieved.
  • Investigate the use of commercial satellite systems such as RADARSAT 8-meter SAR and 1-meter panchromatic sensors for shoreline mapping and quantify the accuracy achieved.
  • Investigate the use of beach profiling techniques (LIDAR, IFSAR, and digital photogrammetry) for determining datum shorelines from data acquired at other tide stages.
  • Explore the use of the VDatum tool for deriving a "mathematical shoreline" from LIDAR data.
