There is big news from the OGC1. From today’s anouncement:

The Open Geospatial Consortium (OGC) is pleased to announce the publication of the SpatioTemporal Asset Catalog (STAC) Community Standards. The STAC family of specifications aims to standardize how geospatial asset metadata are structured and queried. (…)

STAC is purposefully built around a lightweight core and can be adapted using extensions to the standard.

Initially designed for satellite imagery, STAC has evolved to support a wide range of data resources and formats, including aircraft and drone imagery; hyperspectral, optical, and synthetic aperture radar (SAR) data; video; point clouds; lidar; digital elevation models (DEM); vector data; machine learning labels; and composites like NDVI and mosaics.

The STAC specifications include the following:

Like always with OGC standards, these documents are freely accessible.

See also the stacspec.org for a large collection of valuable resources around STAC.
