Re: HLSL30 - Cannot load certain tif into memory

Just chiming in here... I have found that restarting my Python kernel has resolved this error, although I do not know if it works all the time. From my testing, I think the issue may be related to the means by which imagery is processed from STAC into memory. Depending on how you do any compositing,...

Accessing tiled NetCDFs at xarray (MSLSP30NA)

Hello, I am interested in working with phenology data over my study area and want to use the MSLSP30NA product (https://lpdaac.usgs.gov/products/mslsp30nav011/) for that. My goal is to have a gridded product over my area that I can use for easy visualization and as input into modelling. I am familia...

Re: Slow Access to HLS (HLSL30.v2.0, HLSS30.v2.0)

@LP DAAC - afriesz Thanks for the response and notebook! We access thousands of HLS images at a time, so I am not sure about getting a list like that, but maybe there are other ways we can leverage dask on our end. Looking forward to hearing if you find anything on your end in regards to the speed d...

Re: Slow Access to HLS (HLSL30.v2.0, HLSS30.v2.0)

Hello, I cannot share the full notebook for my workflow, but I have attached a simple example based on the basic stackstac tutorial that shows the difference in speed between accessing S2 L2A through AWS E84 and HLS S30 from LPCLOUD. I am not sure how to attach the notebook here on the forum since t...

Slow Access to HLS (HLSL30.v2.0, HLSS30.v2.0)

Hello, I have a workflow that uses HLS (HLSL30.v2.0, HLSS30.v2.0). I access HLS through 'https://cmr.earthdata.nasa.gov/stac/LPCLOUD' using pystac_client and stackstac. It works, but I have noticed it is slow to process these STACs/COGs into memory (e.g., with compute()) when they need to be accesse...

Re: HLSL30 - Cannot load certain tif into memory

I ran the same code again today and it was able to successfully find and load that problematic tif into memory. I guess that means this is some sort of server issue?

HLSL30 - Cannot load certain tif into memory

Hello, I have a set of code that builds an HLS data cube over a given location and time-interval, then runs further processing. As part of that, this data cube needs to be loaded into memory with persist(). The code works well in most scenarios. However, I have found that one particular tif is unabl...
