Modeling AGBD GEDI L4B EarthEngine2

Modeling Forest Aboveground Biomass (AGB) density using GEDI and Sentinel (S1 and S2) Data in Earth Engine

This tutorial will model forest AGB density using Global Ecosystem Dynamics Investigation (GEDI) L4B, Sentinel-1, Sentinel-2, SRTM elevation, and slope data. The GEDI L4B product provides 1 km x 1 km estimates of mean AGB density. We will use the random forest (RF) classifier to model forest AGB density in Earth Engine.

Hey Courage! what a great tutorial! this is incredibly useful.

Thanks for sharing, I would like to know if you have already tried using the NICFI, Landsat-8 and Landsat-9 planet images and the WRI ground cover instead of the ESA LandCover you used??

Excellent work presented. My question is whether these same results can be extrapolated to forage crops for animals. I would like to estimate the biomass of that forage crop. Thank you very much. I'm from Formosa, Argentina

In case of large areas, "Output of image computation is too large", necessarily I can reduce the number of bands, which can affect the accuracy or better reduce the size of the area?

Can i ask why are you using GEDI level 4b product and not level 4a and what is the difference?

Hello. Thank you for the model. But, I am having some errors to my study area. Can you please help me?

thank you for your sharing, where can we find the source code please

I got confused about accuracy assessment and validation. What is the difference? do we need to do both? Thank you for this work

What the max number of RMSE can be tolerated so we get the ideal model prediction?

Hello Courage. Can we use GEDI L4B data for mapping AGBD for the year 2016? Thanks in advance. Can you please share your email?
