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 JSON files, or usually the result of a remote query, that are the items link of a STAC Collection, 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.

Open syntax

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

Open options

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.

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"
