THE PROPOSED WORK WILL CONTRIBUTE TO 1) COLLABORATIVE FOREST INVENTORY EFFORTS BEING UNDERTAKENTHROUGHOUT ALASKA BY NASA AND FOREST SERVICE; 2) AN IMPROVED CHARACTERIZATION OF LANDSCAPE-SCALEBIOGEOGRAPHY OF INTERIOR ALASKA; 3) MORE ROBUST AND AUTOMATED APPROACHES FOR INTEGRATING G-LIHTHYPERSPECTRAL AND LIDAR INFORMATION; 4) IMPROVED UNDERSTANDING OF THE OPPORTUNITIES AND LIMITATIONS FORAPPLYING ALGORITHMS ACROSS FLIGHT LINES GIVEN SUBSTANTIAL ECOSYSTEM METEOROLOGICAL AND ILLUMINATIONVARIABILITY; 5) A CRITICAL SPATIALLY EXTENSIVE BUT FINE-SCALE INCREASE IN OUR UNDERSTANDING OF POST-FIRESUCCESSIONAL DYNAMICS AND STRUCTURAL DEVELOPMENT BOTH OF WHICH HAVE SIGNIFICANT EARTH SYSTEMMODELING IMPLICATIONS; 6) A BETTER UNDERSTANDING OF THE COSTS AND BENEFITS ASSOCIATED WITH EMPLOYINGTLS IN SUPPORT OF BIOMASS ESTIMATION. IN PARTICULAR MANY OF THE DATA PROCESSING AND ANALYSIS WORKFLOWSDEVELOPED IN THIS PROJECT WILL BE OF IMMEDIATE USE FOR DATA COLLECTED IN 2018 OVER THE SUSITNA-COPPERRIVER INVENTORY UNIT.
