The USGS EROS Science Center in Sioux Falls, SD supporting the Core Science Systems Mission Area requests two (2) BLK360 G2 laser scanners. The primary use will be to conduct vegetation surveys in different landscape types to characterize surface and canopy vegetation, fuels type, size, and orientation, and for computation and modeling of various ecosystem monitoring metrics to support ongoing wildland fire science research. These instruments will augment existing instruments as part of a large, multi-agency program and utilize an existing automated data processing, visualization, and distribution system.
