Re: GEDI spatial subset order data from EarthData Search gives ECONNREFUSED error

Hi,
Have you been able to get the Earthdata Search Tool to work for, not sure why it would say connection denied.
After your search is complete and you order the data there should be a Customize Options you can select to subset your area of interest. Will it allow you to do that?
Thanks,
Brett

Re: Strange coords in metadata in VIIRS collections

Hi, The Gring coordinates are not wrong, they are exactly what they are supposed to be. Please see the full list of MODIS/VIIRS tile coordinates here: https://modis-land.gsfc.nasa.gov/pdf/sn_gring_10deg.txt Gring (G polygon) coordinates are not the same as the actual tiles coordinates and are not de...

Re: Status of VIIRS Version 2 Vegetation Indices processing

Hello,
Sorry for the delay. We reached out to the data provider, and the VI processing was allowed to be resumed and they are working there way back and through the gaps. They weren't sure on how long this would take, but the gaps should continually be reduced.
Thanks,
Brett

Re: Gedi Tree height question

It is the highest value of the L1B data, and how that is done is described in the Level-2A ATBD. Section 4.3.4 details how the canopy top (highest detected return) is found. Section 4.3.6 details how the ground (lowest detected mode) is found. Section 5 details how these waveform ranging points (in ...

I would like to know whether the tree height obtained through waveform decomposition is the average height within 25 meters of the light spot size or the highest value of the GEDI L1...

Re: MODIS to VIIRS transition

Hi, You are correct, that is the main premise on the how they produce the 8-day composite. They choose the best available from all 8 daily products. However, I think where the issue may be is that they do not use the QA layer to determine which daily acquisition they chose for the 8-day product. The...
