Jonathan Godt Ph.D.

Program Coordinator

Landslide Hazards

Natural Hazards Mission Area


3dep data to reduce landslide losses

3DEP data improve landslide hazard assessments

  • Enable and improve landslide recognition

  • Improve landslide hazard assessments

  • Repeat collection to document changes and assist response
