NCALM Announces 2021 Seed Proposal Winners

March 9, 2022

2021 Student Seed Proposal Winners Selected

The National Center for Airborne Laser Mapping surveys multiple projects each year for graduate student PIs whose research would be enhanced by airborne lidar data. Students write and submit a two- to three-page proposal to be considered for an award ( The applications are reviewed by the NCALM Steering Committee, who select winners based on intellectual merit and broader impact.

NCALM would like to announce that the 2021 seed proposal winners have been awarded. Nine projects were selected to receive lidar data this year. Congratulations to the following students and their advisors:
