hydromodpy.results.export.stac

STAC Item 1.0 generator for HydroModPy simulations (https://stacspec.org).

Each simulation maps to one Item with:

• bbox and geometry taken from the catalog bbox_xmin..bbox_ymax;

• datetime set to the period midpoint, plus start_datetime / end_datetime when the period covers more than one instant;

• assets describing the Zarr store, every Parquet table, the lockfile and any COG produced by the GeoTIFF exporter (when present on disk);

• properties.proj:epsg and properties.proj:wkt2 from the catalog crs_epsg / crs_wkt columns.

The payload is a plain dict so callers can serialise it without pystac; the optional validate_item() helper relies on pystac.Item.from_dict when the library is installed.

Functions

build_stac_catalog(*, catalog_id, title, ...)	Return a STAC Catalog listing every project collection on disk.
build_stac_collection(items, *, collection_id)	Return a STAC Collection that groups items under collection_id.
build_stac_item(context)	Return one STAC Item for the simulation referenced in context.
validate_item(payload)	Validate an Item dict with pystac when installed.
write_stac_catalog(output_path, *, catalog_id)	Render and write a STAC Catalog to output_path/catalog.json.
write_stac_collection(items, output_path, *, ...)	Render and write a STAC Collection to output_path/collection.json.
write_stac_item(catalog, sim_id, output_path, *)	Render and write the STAC Item for sim_id.
