Hi folks,

Do you have any recommendations regarding workflows [that work] for easily opening + reading the Tanager HDF5 data you have provided via: https://www.planet.com/data/stac/browser/tanager-core-imagery/catalog.json? I have managed to open some scenes in SNAP, but they don’t seem to be exporting properly to GeoTIF. Any suggestions would be welcome, as I assume that others participating in the competition might run into similar issues. Thanks!

Emil

UPDATE: I was able to get the data processed with SNAP (version 13), which required reprojecting from the “basic_sr_hdf5”, and then exporting as a GeoTIF. I will draft up some documentation on how that’s done and share it as it might help folks get over the first barrier of just opening the data.

Oh, that’s brilliant, ​@Emil Cherrington!  I think our colleague ​@keely.roth will have some additional thoughts on this. But I’m just appreciative of your quick-thinking and reporting back -- thanks for all you do!

Thanks, Amy! I appreciate it. I look forward to hearing from Keely, but I have worked out the process of extracting the data using SNAP (which is open software) in a few steps. I now have the 4 Tanager scenes I intend to work with extracted as GeoTIFs, and I’m uploading them to Earth Engine where I’ll be able to compare them with open data from NASA’s EMIT and PACE OCI (along the guidelines of the competition, which asks for EMIT and PRISMA). I do need to develop some tooling to work with the cumulative 866 bands of the Tanager data, which is a wee different from EMIT / EO-1 Hyperion / PACE OCI.

FWIW, I appreciate that there’s at least one scene over Belize. 😉
