Full Title: ELVIS : USGS NGP Lidar Research and Development Tool for Future 3DEP Lidar Accuracy Requirements

Instructor(s)

Minsu Kim


USGS NGP supports the research for accuracy assessment of 3DEP lidar point cloud to establish potential future accuracy requirements of 3DEP data. ELVIS is a research and development tool for NGP lidar research developed at USGS EROS lidar team. The workshop will address

  • Theoretical background of Airborne lidar simulation software (Radiative-transfer and Georeferencing)
  • Investigation of the functionalities of the lidar simulator in terms of laser, scanner, and target module
  • Summary of lidar accuracy definitions from USGS lidar base specification
  • Development of generalized external uncertainty model using 3-plane intersection point
  • Development of generalized external uncertainty model using line-crossing point
  • 3DEP accuracy assessment (Absolute Vertical Accuracy)
  • Horizontal accuracy in the context of 3D Accuracy assessment
  • Types of geometric feature-based GCPs found in the point cloud
  • Application of 3D accuracy using Ground Truth Survey data
  • Application of 3D accuracy using Mobile lidar data (Here Technology)

Connection details will be sent to registrants prior to the workshop.
