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 STAC API ItemCollections, with the input usually being a STAC API search query or the results saved as a JSON file. Items in the response must include projection information following 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.
Note that STAC API ItemCollections are not the same as STAC Collections. STAC API ItemCollections are GeoJSON FeatureCollections enhanced with STAC entities.
STACIT datasets/subdatasets can be accessed with one of the following syntaxes:
filename.json: local file
STACIT:"https://example.com/filename.json": remote file or query
STACIT:"filename.json":asset=my_asset: specify the name of the asset GDAL should read (i.e. "visual")
STACIT:"filename.json":collection=my_collect,asset=my_asset: limit to items in a given collection and specify asset to read
STACIT:"filename.json":collection=my_collect,asset=my_asset,crs=my_crs: specify a collection, asset, and limit to items in a given CRS
The following open options are supported:
MAX_ITEMS=<integer>: Defaults to
1000. Maximum number of items fetched. 0=unlimited.
COLLECTION=value: Name of collection to filter items.
CRS=value: Name of CRS to filter items.
ASSET=value: Name of asset to read.
RESOLUTION=[AVERAGE/HIGHEST/LOWEST]: Defaults to
AVERAGE. Strategy to use to determine dataset resolution.
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:
