STAC (Spatio-Temporal Asset Catalog) is a JSON specification for indexing geospatial information.
STAC Item is a JSON representation of a single feature and contains one or more assets; each asset contains a URL to its associated raster image. JSON formats such as STAC ItemCollection, STAC Catalog, and STAC Collection can contain one or more STAC Items.

Reader Overview
FME considers a single JSON file, URL to JSON file, or URL to query that returns JSON data, to be a dataset.
The following JSON formats are supported:
-
STAC Item
-
STAC ItemCollection
-
STAC Catalog or STAC Collection, with an “items” link
-
STAC Catalog or STAC Collection, with one or more “item” links
A STAC Catalog or STAC Collection that only links to other Catalogs or Collections is not supported.
For all formats, FME requires STAC Items to implement the STAC Projection Extension.
The Feature Type for STAC Items is configurable with the Feature Type Name parameter. By default, the Feature Type will be [collection_name].[asset_name].
The STAC Item Reader produces one raster feature for each item.
FME Raster Features
FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.
