STACIT - Spatio-Temporal Asset Catalog Items
New in version 3.4.
Driver short name
STACIT
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.
Open syntax
STACIT datasets/subdatasets can be accessed with one of the following syntaxes:
filename.json
: local fileSTACIT:"https://example.com/filename.json"
: remote file or querySTACIT:"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 readSTACIT:"filename.json":collection=my_collect,asset=my_asset,crs=my_crs
: specify a collection, asset, and limit to items in a given CRS
Open options
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.
Subdatasets
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.
Driver capabilities
Supports VirtualIO
This driver supports virtual I/O operations (/vsimem/, etc.)
Examples
List the subdatasets associated to a STAC search on a given collection, bbox and starting from a datetime:
gdalinfo "STACIT:\"https://planetarycomputer.microsoft.com/api/stac/v1/search?collections=naip&bbox=-100,40,-99,41&datetime=2019-01-01T00:00:00Z%2F..\""
Open a subdataset returned by the above request:
gdalinfo "STACIT:\"https://planetarycomputer.microsoft.com/api/stac/v1/search?collections=naip&bbox=-100,40,-99,41&datetime=2019-01-01T00:00:00Z%2F..\":asset=image"
