Re: 404 Not Found for Granule Metadata File MOD13A2

africanriskcapacity , Thanks for point this out. As you probably know, the LP DAAC is migrating its on-prem data to the Earthdata Cloud. With this comes a few changes, which you stumbled upon, and we apologized for the inconvenience. The .hdf.xml file you know from the on-prem data distribution sys...

Re: Unable to access HLSS30.020 on aws s3

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.

This change makes the attributes available to utilities/packages that handle applying...

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.
