Overview

NCALM Project. PI: Praveen Kumar, University of Illinois. The survey area consisted of a polygon located near the confluence of Ohio and Mississippi rivers, about 35 km east of Sikeston in the southeastern edge of the state of Missouri. These data were collected as a rapid response to a flooding event on the Mississippi River. The data were collected June 21-23, 2011.
