UNAVCO TLS Workshop – October, 2011

Background

CRREL »  ~350 employees on a 20+ acre campus in Hanover, NH

Remote Sensing and GIS Center of Expertise (RS/GISC) »  30+ R&D personnel

•  Hypothesis driven basic research •  Applied science in the field •  Tech transition to industry and government partners

My Background

»  Glacial / Fluvial Geomorphologist »  Specialize in quantifying geomorphic and geologic processes using remote

sensing techniques »  10+ years at CRREL »  Alaska, Antarctica, Greenland and Iceland

UNAVCO TLS Workshop – October, 2011

LiDAR Research

Approach

»  Tool for quantifying essential boundary conditions necessary to answer or support basic and applied research

•  Airborne, terrestrial and mobile/marine platforms

»  Develop and enhance existing LiDAR sensors •  Multi-sensor fusion •  Additional wavelengths for specific geologic/scientific applications •  Autonomous systems

»  Develop tools and techniques for enhanced acquisition, analysis and dissemination

•  Open-source libraries and software libLAS, LASzip, PDAL, GDAL and OGR

•  Database systems for global point cloud management •  Well-written specifications and standards

Snow - Automated LiDAR

»  Automated LiDAR System designed for long-term, repeat laser scan observations from a fixed location

»  Enables repeat 3D measurements over a long-term period without user input

»  The system incorporates three components: •  Riegl LMS-Z390i terrestrial laser scanner •  Housing and hardware package •  Automation Process which runs specified scans at

programmable intervals
