Canopy top height models at 10m GSD from airborne LIDAR (derived from LVIS and small-footprint ALS)

Rasterized canopy top height models (CTHM) at 10m ground sampling distance (GSD) derived from airborne LIDAR.

The CTHMs were created to be comparable to GEDI canopy top heights (within 25m footprints) using two sources:

1) NASA's LVIS airborne LIDAR campaigns (here we rasterized the RH98).
2) High-resolution canopy height models derived from small-footprint airborne laser scanning campaigns in Europe (max pooled with a circular 25m footprint corresponding to the GEDI footprint).

The original LVIS LIDAR data is available here: https://lvis.gsfc.nasa.gov

Code to create GEDI-like canopy top heights from high-resolution ALS data is available here: https://github.com/langnico/global-canopy-height-model
