Geospatial Data and Services
Our map services have recently moved and are now hosted at https://gis.ngdc.noaa.gov/. References to services previously found at https://maps.ngdc.noaa.gov/ will need to be updated. The map viewers remain at https://maps.ngdc.noaa.gov/.
Although we strive to minimize breaking changes, the continued evolution of our geospatial framework sometimes requires them. We apologize for any inconvenience.
