The third sentence in the second paragraph of The National Map Section contains these changes.

	- deleted the hyphen in "(1:24,000-scale)"
	- inserted "(fig. 1)" after "layers"

The corrected sentence is shown below.

The majority of The National Map effort is devoted to acquiring and integrating medium-scale (nominally 1:24,000 scale) geospatial data for the eight base layers (fig. 1) from a variety of sources and providing access to the resulting seamless coverages of geospatial data.
