NOAA Inspection, Survey & Testing Enhanced
National Geodetic Survey
NOAA's National Geodetic Survey maintains the national elevation reference system and publishes post-storm aerial imagery of coastal damage.
Description
The National Geodetic Survey (NGS) is a NOAA office whose work supports precise mapping, infrastructure planning and flood risk assessment.
Key features
- Post-storm aerial imagery of coastal damage published online, for example imagery of Pensacola, Florida, after Hurricane Isaias
- GPS on Bench Marks (GPSonBM) program, in which volunteers with survey-grade GPS receivers collected location data at permanent survey benchmarks
- Improving the accuracy of the national elevation reference system and modernizing the national geodetic framework
- Contributes to NOAA's charting and mapping work alongside the Office of Coast Survey
Applications
- Precise mapping and positioning
- Coastal infrastructure planning and flood risk assessment
- Post-storm damage assessment
