Virtual products for the OpenDataCube

Virtual products for the OpenDataCube

Useful applications for virtual products:

• Rasterfile product (not needing to index).
• Shapefile product (encapsulating rasterisation).
• Band math (simple computations on the fly, without needing to store).
• Composite products (handling join and ensuring mutual availability, e.g., bands from NBAR together with from PQ) and grouped products (e.g. Landsat 5, 7 & 8).
• Masked products (encapsulating boilerplate and topic expertise), e.g. cloud-free imagery.
• Temporal clustering (reconstituting satellite passes to avoid duplicate observations).
• Complex filtering (beyond any API limitations, perhaps even accessing external metadata, e.g. filtering by quality scores)
• Locally cached products.
• As a flexible base from which to prototype/refactor datacube concepts (not constrained to reflect entrenched structure of data holdings)
