STACIT - Spatio-Temporal Asset Catalog Items
New in version 3.4.
Driver short name
Driver built-in by default
This driver is built-in by default
This driver supports opening JSON files, or usually the result of a remote query,
that are the
items link of a
and whose items also implement the
Projection Extension Specification.
It builds a virtual mosaic from the items.
A STACIT dataset which has no subdatasets is actually a VRT – GDAL Virtual Format dataset. Thus, translating it into VRT will result in a VRT file that directly references the items.
STACIT datasets/subdatasets can be accessed with one of the following syntaxes:
filename.json: local file
STACIT:"https://example.com/filename.json": remote file
STACIT:"filename.json":asset=my_asset: specify an asset of a local/remote file
STACIT:"filename.json":collection=my_collect,asset=my_asset: specify a collection + asset of a local/remote file
STACIT:"filename.json":collection=my_collect,asset=my_asset,crs=my_crs: specify a collection + asset + CRS of a local/remote file
The following open options are supported:
MAX_ITEMS= number. Maximum number of items fetched. 0=unlimited. Default is 1000.
COLLECTION= string. Name of collection to filter items.
ASSET= string. Name of asset to filter items.
CRS= string. Name of CRS to filter items.
RESOLUTION= AVERAGE/HIGHEST/LOWEST. Strategy to use to determine dataset resolution. Default is AVERAGE.
If a STACIT JSON file contains several collections, assets or CRS, the driver will return a list of subdataset names to open each of the possible subdatasets.
This driver supports virtual I/O operations (/vsimem/, etc.)
List the subdatasets associated to a STAC search on a given collection, bbox and starting from a datetime:
