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() / lazy_stac_stack() consume 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.
