A Method for Extracting Stream Channel Flow Paths from LiDAR Point Cloud Data
LiDAR Point Cloud Streams
2015/8/14
Traditional methods of delineating stream channel networks use gridded raster elevation data. Direct use of LiDAR point clouds, without first creating a raster or grid, could improve efficiency and ac...
