Managed Areas
A delineation of managed areas (Federal, State, tribal, and military lands) from the USGS National Atlas was overlaid on the topographic change inventory. Note that this representation of managed lands is from a small-scale map source and does not include all Federal lands, while others are generalized. About 11 percent of the change polygons fall within the general boundaries of the managed areas (see figure below).
Managed areas (Federal, State, tribal, and military lands) that contain topographic change polygons. About 11 percent of the change inventory polygons fall within the general extent of these managed areas.
Presumably, some of these change polygons are on the private land holdings that are encompassed by the general extent of the managed areas.
