Open Data Cube – Indexing Data from Microsoft Planetary Computer

open-data-cube

I would like to index into ODC some data from the Sentinel-2 dataset available on Microsoft Planetary Computer (PC).

The main issue is with the PC's requirement of using tokens (SAS), which need to be appended to the URLs exposed by the STAC API, the ones then indexed in ODC.
Those URLs will not have any token attached, resulting in 404 requests when trying to use dc.load().

What is the recommended approach in this case? I have seen support in the odc-stac project, but I understand it doesn't index data in an ODC database, while I would like to have the data indexed.
Is that correct?

Best Answer

Planetary Computer support has been added in ODC through the patch_url parameter in dc.load() - docs - since v1.8.8, and with Dask support since v1.8.9.

This is an important question, and the short answer is that it's a really good idea, but it's not done a lot.

The normal practice for the Open Data Cube is to develop analyses in Python code in a notebook and if that analysis becomes a product, it will be re-developed a little into a data production pipeline of some description.

Two examples common in Digital Earth Australia and Digital Earth Africa are Datacube Alchemist and Statistician.

Another alternative is to develop your own metadata that goes along with the data you're producing. I like doing this using Rio STAC, just make sure to include the Projection extension.

open-data-cube – How to Fix Error While Indexing Sentinel 2 Data on Open Data Cube

For Sentinel-2 indexing into the Open Data Cube, I recommend using the Element-84 maintained Sentinel-2 COGs, which are available for free from S3.

There's some documentation here on how to index the data.

In brief:

pip install --extra-index-url="https://packages.dea.ga.gov.au" odc_apps_dc_tools

stac-to-dc \
--catalog-href='https://earth-search.aws.element84.com/v0/' \
--bbox='25,20,35,30' \
--collections='sentinel-s2-l2a-cogs' \
--datetime='2020-01-01/2020-03-31'
