NGS has traditionally used only airborne photography for its mapping missions. However, the advent of high resolution spaceborne imagery may be useful for precision mapping projects. NGS has recently used spaceborne imagery as a reconnaissance tool to evaluate the temporal accuracy of previously compiled shoreline data. |
NGS is experimenting with a wide variety of spaceborne commercial imagery to conduct similar studies of shoreline accuracy. |

from Space Imaging
to facilitate research into shoreline mapping using spaceborne data sources.
