Postconstruction tin of land surface on the Missouri River downstream from Gavins Point Dam near River Mile 761.4

This geospatial data set contains an interpolated 3-D surface or, triangulated-irregular network
(TIN), of the substrate surface between cross-sections 23 and 39 following construction of
Emergent Sandbar Habitat near River Mile 761.4. The surface was generated from points
collected by the echosounder and real-time kinematic (RTK) GPS on cross-sections in the
downstream project reach surrounding the construction area at River Mile 761.4 below
Gavins Point Dam on the Missouri River in South Dakota.
