Hey @alvioli ,
We recently made some updates to the GEDI tutorials found here: https://git.earthdata.nasa.gov/projects/LPDUR/repos/gedi-v2-tutorials/browse in response to your question. The output geojson files for the L2A and L2B tutorials should both include the selected_algorithm.

Re: Query about GEDI time quantum
deace , The areas of no observations, or the ‘rhombus-shape’, you are seeing is a result of a couple things (probably more, but I’ll mention the things I know about). The first being the ISS orbit and the second being the altitude of the ISS. The ISS has a precessing orbit and not a polar orbiting ...

Re: Query about GEDI time quantum
deace , Would you be able to share a link to the ICESAT-1 campaign table? I'm curious what it looks like. I don't think there is a 'table' containing the revisit intervals. Is there any reason why Earthdata Search doesn't at least get you partially there? You can search for you area of interest usi...

Re: how to extract the exact the shape of GEDI shots
deace , I think what you’re looking for is the GEDI L1B Geolocated Waveform Data ( https://lpdaac.usgs.gov/products/gedi01_bv002/ ). This product provides geolocated corrected and smoothed waveforms, which when plotted gives you the ‘pulse shape’. The GEDI_L1B_V2_Tutorial.ipynb tutorial in https://...

Re: CMR has no entries for MOD13Q1.061 files at LP DAAC
zhan.li & earthengine_urs , As was mentioned before, the LP DAAC is in a state where on-prem data is actively being moved to the NASA Earthdata Cloud. When those on-prem (i.e., provider=LPDAAC_ECS) collections are moved to the cloud (i.e., provider=LPCLOUD) they receive a new concept ID, AND th...

Re: Query about GEDI time quantum
deace , It is not clear to me what you’re asking for exactly. GEDI continuously collects lidar samples globally from the International Space Station. If you’re trying to find and access data that spatially and temporally intersect with you research parameters, I would recommend using Earthdata Sear...

Re: MODIS data exposed through CMR STAC API
valpesendorfer , The LP DAAC currently has two provider endpoints within the CMR STAC API. One for "LPDAAC_ECS" ( https://cmr.earthdata.nasa.gov/stac/LPDAAC_ECS/ ) and one for "LPCLOUD" ( https://cmr.earthdata.nasa.gov/stac/LPCLOUD/ ). The LPDAAC_ECS endpoint will contain metada...

Re: How to calculate NDVI from MODIS MOD09GQ?
@5479584.asdf, I was able to replicate what you are seeing in QGIS. I don’t see a problem other than you should be quality filtering these data before you calculate the NDVI. The MODIS granule you downloaded will have a “QC_250m_1” layer in it that you should use to quality filter your data. The QA ...

Re: Reprojection
rkshah , From what I can tell, what you are seeing is what is expected. The rows and columns of the grid will change, as well as the pixel count, when you transform from the Sinusoidal grid to your UTM projection. Any tool or utility that reprojects will exhibit this. Is there anything else that le...
