Rectangularise STAC items into a source table.

One row per item x asset. The result is a plain data frame: the stac_filter_* helpers operate on it in ordinary R, and lazy_dataset() consumes it to build lazy mosaics.

Usage

stac_sources(items, assets = NULL)

Arguments

items

An rstac doc_items object (or any list with the same features structure).

assets

Optional character vector restricting assets.

Value

A data.frame with one row per item x asset and columns item_id, asset, location (GDAL-readable href), datetime, cloud_cover, and the footprint columns xmin, ymin, xmax, ymax (EPSG:4326, from the item bbox), sorted by datetime, item and asset.
