This appears to be resolved by 23c085e2ad86b (alas at the expense of #111). Ideally would still narrow this down (and feed into a regression test, to ensure compatibility with the next stable release of datacube-core).
WIT appears to be outputting many parquet files that contain only column headers, and no data rows.
Appears to be related to geopolygon transformations. Possibly a reprojection (CRS84 vs EPSG:4326 vs EPSG:3577) bug in ODC core 1.8.3 virtual products?

Logs of
WIT.process_data(data, parameters)
seem to show the method call is invoked with the expected vector input, supplied inparameters['feature']
:But
WIT.process_data
has simultaneously been supplied anxarray
of raster data with the wrong spatial extent, at least according todata.geobox
: lon/lat truncate to 168,-28Consequently, after invoking a (via wrapper)
rasterio.features.geometry_mask
(to overlay the vector geometry feature onto the raster defined by the xarray geobox),WIT.process_data
finds no pixels (and logs the polygon area as zero), and ultimately returns an emptypandas.DataFrame
(with column headings but no index rows).h/t @emmaai
