The Navy and other Department of Defense activities collect and archive large amounts of imagery of the Earths seafloor and terrestrial surfaces for distribution to users in the tactical, intelligence, or scientific communities. This imagery is high resolution and collections can be quite large the compressed 1 meter per pixel imagery of the U.S. is approximately 3 terabytes. Storing the high-resolution imagery as flat files on a hard drive or in a database is problematic because the system must perform time-consuming loading, decoding, and post-processing of large numbers of images for every request by a user. The tile archival and distribution system developed by the Naval Research Laboratorys Mapping, Charting, and Geodesy Branch of its Marine Geosciences Division solves these problems and provides a sophisticated and comprehensive method of imagery management.
