Re: Unable to access HLSS30.020 on aws s3

I'm still looking in to why the code you posted does not work. Seems like it should but I'm getting an access denied error as well. In the meantime, the below code may be able to help. It uses Python's s3fs instead and shows how to list the contents within a bucket and how to download a file. ``` im...

Re: Appeears - MOD11a2 - Scaling factor added to tif via tiftag?

pzellner , You are correct. On 2023-01-23 there was an AppEEARS release that included a modification to the output Cloud Optimized GeoTIFF files that added the `Offset` and `Scale` attributes to the Band metadata. This change makes the attributes available to utilities/packages that handle applying...

Re: lpdaacsvc.cr.usgs.gov/services/inventory - MOD09A1.061

brrodrigo98 , The inventory service you are using is a legacy service that does not support MODIS Collection 6.1. We recommend transitioning your search requests to the CMR API (https://cmr.earthdata.nasa.gov/search/site/docs/search/api.html). Here are some resources that may help in the transition...

Re: Can't find selected_algorithm in L2A GEDI elevation and canopy height dataset

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.

Question: Query about GEDI time quantum

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...
