LIDAR Method. The development of channel locations from LIDAR is a standardized process, but involves making choices, all of which impact the final outcome. The general approach involves the following steps: develop a digital elevation model (DEM), perform a flow accumulation on the DEM, set a flow accumulation threshold to determine the perennial initiation point, and convert the result to a vector GIS dataset. Details of the specific processing performed for this project are available in Appendix A.
