AB: This paper describes a remote sensing method to map mangrove canopy structure at the landscape scale using synergy between Lidar and inSAR. While the inSAR data allows landscape scale mapping of canopy height, the Lidar data is used with an inversion model to retrieve tree size distribution within the footprint. The tree size distribution is then used as an input to a mangrove ecological model to estimate ecosystem productivity throughout the landscape. The inversion uses mangrove tree architecture and assumes the Lidar measures the canopy surface. This assumption was verified using coincident airborne Lidar and Spaceborne ICEsat/GLAS data in Everglades National Park. A user-friendly web interface is presented to examine inSAR derived canopy height and examine ICEsat/GLAS Lidar waveforms over several mangrove sites around the Caribbean and Gulf of Mexico. The interface also allows the user to interactively analyze the waveforms and estimate local ecosystem productivity with user-defined input parameters on nutrient availability and stressors
