Integrate earthsearch AWS S2 COG STAC access #23

Closed fbalaban closed 2 months ago

fbalaban commented 3 months ago

There is a STAC collection of: S2 L2A, S2 L1C, S2 L2A COGs and Landsat 8 L1C1 items. https://earth-search.aws.element84.com/v0

This collection has free cloud access and is accessible through STAC search.

This issue/PR will introduce search and download of the S2 COGs by using STAC search, so to gradually introduce STAC procedures to the Harvester.

Preliminary work has already been implemented by @tdrivas on the main branch and folder STACReader

The aforementioned preliminary work, loads the items into an Open Data Cube. While this is a requested functionality, it could be considered as a "preprocessing" step, in the sense that it takes a decision on where to load data to.

This issue will only deal with downloading the data to a predefined folder. And a new issue (maybe in Harvester, maybe in a new processor) will have to open to tackle the destination issue.
