Dear colleagues,

I am working on developing a canopy height map using GEDI Level 2A data - rh98. I downloaded the data into Google Earth Engine, applied a quality flag mask, and checked the data, as shown in the attached .png image. There are points with a height of 130m. I performed a search and found that 1,475 points fall between 42m and 140m, while the maximum expected canopy height for this area is 40m. I also incorporated slope data, but there are anomalous values for all slope levels.

Has anyone had experience with this? Is it correct to simply delete these points?

Hi @loriesouza Thanks for writing in. Could you please provide some of the granule IDs of the data where you are seeing this issue? We will see if we are seeing it within the GEDI data we provide. It sounds like you downloaded the data from the LP DAAC and added it to GEE yourself? Is that accurate? If you think it might be an issue within GEE itself, or if you received the data directly from GEE, we recommend reaching out to their team for assistance: https://developers.google.com/earth-engine/help
