USA - Quantum Spatial Completes Data Collection for NOAA's Largest Coastal Mapping Project

Unique Combination of Sensors Used to Gather High Resolution Topographic and Bathymetric Lidar Data Along 12,000 Square Miles of Eastern Seaboard and Gulf Coast Areas Not Surveyed Since Civil War Era


Quantum Spatial, Inc., an NV5 company and North America’s largest geospatial data firm, recently completed the collection of topographic and bathymetric lidar and digital imagery for the National Oceanic and Atmospheric Administration’s (NOAA) largest coastal mapping project. These efforts include updating information for 12,000 square miles along the Eastern Seaboard, Pacific, and Gulf Coast that have not been surveyed for hundreds of years.

Quantum Spatial, which is serving as the prime contractor for collection and processing of the data under this previously announced NOAA Coastal and Geospatial Services contract, devised an innovative approach, simultaneously using multiple sensors to achieve accurate data collection in various depths of water and along the shoreline.

“The data collected is at a resolution and accuracy that is far superior to what we have had available to us,” said Mike Aslasken, chief of the Remote Sensing Division for NOAA’s National Geodetic Survey. “Some of these areas have not been surveyed since the Civil War era, and the technology being used provides us insights on water depth for our nautical charts, especially in shallow areas that are impossible to chart by more traditional means. These surveys will provide an important baseline and offer long-lasting value to other stakeholders, who will leverage it for a variety of applications.”
