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

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...

Re: How to merge the modis tile data to obtain a global distribution

uranus21240 , Indeed, you can use AppEEARS ( https://lpdaacsvc.cr.usgs.gov/appeears/ ) to request a global mosaic of MCD15A2H variables at their original or native spatial resolution. The AppEEARS system does not resample data to optional spatial resolutions. This something that would need to take ...

Re: Provisional HLS Version 1.5

sidharth94 , I can't speak toward what you're seeing with the AWS Sentinel-2 L2A COGs. With he HLS collection there will be occasions when Landsat 8 and Sentinel-2 capture observations on the same day for the same area. The HLS L30 and S30 COG files will have the same date stamp but will have a dif...

Re: AppEEARS API

@ mchl.mccrthy , The token generated from the AppEEARS API to 'login' is separate from the tokens generated from the Earthdata Login. Here are a couple things to consider. First, if you ran your request on Wednesday, you may have bumped into the LP DAAC's planned maintenance window. If that's the ca...

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

Good morning daviluca , The day of year (doy) for each geoTIFF output from AppEEARS can be found in the file name. For example, the doy for this AppEEARS output, MOD11A2.006_LST_Day_1km_doy2021129_aid0001.tif , is 129 for the year 2021 (doy2021129). This translates to the date 05/09/2021 ( https://w...
