Types of Datasets¶
When using the Data Cube, it will contain records about 2 different types of products and datasets.
| Type of dataset | In Index | Typical data |
|---|---|---|
| Indexed | Yes | Created externally |
| Ingested | Yes | Created within the Data Cube |
Indexed Datasets¶
Data is available (has a file location or uri), with associated metadata available in a format understood by the Data Cube.
Example:
- USGS Landsat Scenes with prepared
agdc-metadata.yaml - GA Landsat Scenes
Ingested Datasets¶
Data has been created by/and is managed by the Data Cube. The data has typically been been copied, compressed, tiled and possibly re-projected into a shape suitable for analysis, and stored in NetCDF4 files.
Example:
- Tiled GA Landsat Data, ingested into Australian Albers Equal Area Projection (EPSG:3577) and stored in 100km tiles in NetCDF4
