The standard maps are created in two basic formats, called “10K” and “1K”. These formats represent the map extents based on the 10 kilometer (10K) and 1 kilometer (1K) increments of the U.S. National Grid (USNG), and are named accordingly.

Some of the maps include an overlay of the 100 year FEMA flood zone and do not represent the actual flooding or potential flooding. They are only intended as a guide and as an example of the capability to easily produce situational overlays on USNG maps.
