Re: Downloading GEDI data from e4ftl01.cr.usgs.gov results in 302 redirects

cgrotz , I'm still looking into why the 'curl' option is not working. In the meantime, would you be willing to try 'wget' ( https://www.gnu.org/software/wget/ ) instead? I've been able to successfully download your link and the .h5 data link with wget. An example wget call is below: wget https://e4...

Re: Negative GEDI RH Metrics

ahonda , I have a couple questions for you. 1. Are you downloading the source .h5 files first and then processing the files, or are you subsetting the files in Earthdata Search first? 2. Could you share the code you're using to process the data or are you using the GEDI tutorials available here: ht...

Re: How to make a time series based on pixel location

@daviluca ,

Would you be able to share the vector files you're using and your AppEEARS request ID? If so, please send to LPDAAC@usgs.gov with the subject "Forum: How to make a time series based on pixel location".

@antjeuhde ,

Are you still experiencing the error described previously? What GEDI data products are you downloading? Would you be able to share the python script you using to download these files?

Re: Foliage Height Diversity calculation in GEDI

ctampion , fhd_normal is calculated using a 1 m resolution pavd_z profile, instead of the 5 m resolution used for the pavd_z, pai_z, and cover_z profiles available in the L2B product. The 1 m pavd_z profile is not available in L2B, but it is possible to recalculate it from the pgap_theta_z profile....

Re: Wildfires Data Pathfinder

@ jxm2127 , Take a look at the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) ( https://lpdaacsvc.cr.usgs.gov/appeears/ ). AρρEEARS gives you the ability to access multiple data products and subset geospatial datasets using spatial, temporal, and band/layer parameters. Ma...

First, I cloned the repository ( https://git.earthdata.nasa.gov/projects/LPDUR/repos/gedi-subsetter/browse ) to a local directory, and I ran the Python Environment setup instructions (i.e., conda c...

Re: Is there an API for spatially subsetting and downloading GEDI data?

nathanmthomas , At this time there is no public API or web service that can spatially subset GEDI data prior to downloading. The GEDI helper scripts and tutorials produced by the LP DAAC do require a local copy of the data before any processing/subsetting occurs. Indeed, Earthdata Search is able to...

Re: Interpreting floating-point QC values from OPeNDAP MOD21A1D

kodiologist , Thank you for pointing out this issue. The OPeNDAP URL you are accessing is one that is configured to automatically apply scale factors and offsets to the science datasets. This issue was unknown to us. We will investigate this behavior for that OPeNDAP URL. We do have another OPeNDAP...

Re: AppEEARS API

mchl.mccrthy , We strongly encourage anyone working with data from any NASA DAAC to consult the associated quality data layers or metadata. The automatic return of associated quality data is a foundational component of the AppEEARS system and is something we cannot turn off. However, data files pro...
