Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019 Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019
A geometric accuracy assessment of lidar data collected in eastern Iowa in 2019 as part of the 3D Elevation Program (3DEP) was conducted. The assessment involved evaluating interswath accuracy, same surface precision, point density, absolute accuracy, and consistency with adjacent 3DEP datasets. The results demonstrate that the data meet or exceed the quality level 2 specifications...
Lead exposure in waterfowl before contoxic shot requirements: A nationwide study, 1983−1986 Lead exposure in waterfowl before contoxic shot requirements: A nationwide study, 1983−1986
Before implementing nontoxic shot requirements for hunting waterfowl and American coots Fulica americana in the United States in 1991, the U.S. Fish and Wildlife Service monitored lead poisoning in waterfowl on federal and state wildlife hunting areas during 1983-1986. Federal and state collaborators collected gizzards and livers from 9,029 hunter-killed waterfowl (10 species of dabbling...
