(2)
develop maps that depict zones that are at greater risk of sinkhole formation.
(b) Use of certain data
In developing maps under subsection (a)(2), the Director of the United States Geological Survey shall utilize 3D elevation data (as that term is defined in section 2 of the National Landslide Preparedness Act (43 U.S.C. 3101)) collected pursuant to section 5 of that Act (43 U.S.C. 3104).
(c) Review of maps
