North Dakota GIS Conference 2006: Presentations
LIDAR 101: Intro to LIDAR
Presented by: Jason Stoker, Senior Scientist, Science Applications International Corporation (SAIC), USGS Earth Resources Observation and Science (EROS)
This presentation will provide an introduction and overview to Light Detection and Ranging (LIDAR) technology. We will explore the system components, differences between small footprint discrete return lidar and continuous waveform large footprint systems. We will overview how the system operates, how systems can vary, what LIDAR data looks like, and how we go about processing small footprint LIDAR data. Focus will be on specific technical issues and lessons learned by users processing, analyzing, visualizing and distributing lidar data sets. New tools and techniques being used specifically at the U.S. Geologic Survey National Center for EROS will be discussed in detail. We will discuss not only how LIDAR is being used for bare earth DEM generation, but how we can extract vertical vegetation and structural information from the resultant LIDAR returns.
