GTiff/sample_by_feature of spatial data cube returns only a single asset #681

Open bossie opened 4 months ago

Unlike netCDF, saving a spatial data cube to GeoTiff with sample_by_feature enabled, will result in only a single asset/STAC Item.

Process graph with 25 input features: process_graph.json

Corresponding job results with only a single output GeoTiff: job_results.json

FWIW the single GeoTiff is what you would expect for sample_by_feature: false: it covers the entire envelope but only has valid pixels for the input features, the rest is NODATA.
