ASPRS 2021 Workshop: ELVIS: USGS NGP Lidar Research and Development Tool for Future 3DEP Lidar Accuracy Requirements

May 3 @ 12:15 PM - 2:15 PM EDT

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)
