A product definition defines what a dataset must look like and provides load hints to Datacube, as well as basic metadata about a product.
metadata section of a product definition is used to automatically match
the product to a dataset. The simplest product definition is included below.
This example uses only one measurement (equivalent to an
asset in STAC)
and some very basic information about the product
--- name: dem_srtm metadata_type: eo3 metadata: product: name: dem_srtm measurements: - name: elevation dtype: int16 nodata: -32768.0 units: "metre"
A slightly more complex product definition is shown below. This example uses
storage section to provide load hints, so that default parameters are
known when loading data.
--- name: dem_srtm description: 1 second elevation model metadata_type: eo3 license: CC-BY-4.0 metadata: product: name: dem_srtm storage: crs: EPSG:4326 tile_size: x: 100000.0 y: 100000.0 resolution: longitude: 0.000277777777780 latitude: -0.000277777777780 measurements: - name: elevation dtype: int16 nodata: -32768.0 units: "metre"
You can add product definitions using the command line as follows:
datacube product add <path-to-file>
and you can update them using
datacube product update <path-to-file>.
A tool exists that can help you keep products in sync between a CSV list of products and the ODC dataset. See the datacube-product-sync tool.
