FAQPage Schema

How do I validate a STAC catalog for geospatial metadata interoperability?▼

To validate a STAC catalog, ensure your JSON and GeoJSON content conforms to the STAC core specification, includes RFC 8288 web links, and correctly implements required catalog, collection, and item object structures for consistent geospatial discovery.

What is a STAC collection and when do I need it for geospatial data?▼

A STAC collection organizes related geospatial items with standardized metadata. You need it when grouping multiple spatial datasets to ensure consistent discovery, interoperability, and scalable integration across diverse geospatial workflows.

How do I create STAC items that support common extensions?▼

Create STAC items by structuring GeoJSON features with required metadata fields, ensuring RFC 8288 links, and applying common STAC extensions to guarantee interoperability and proper validation across diverse geospatial data catalogs.

Does STAC validation check RFC 8288 web links and GeoJSON compliance?▼

Yes, STAC validation checks RFC 8288 web links and GeoJSON compliance to ensure your catalog, collection, and item objects fully conform to the STAC core specification and common extensions for reliable geospatial interoperability.

What's the best way to structure STAC catalogs for scalable geospatial discovery?▼

The best way to structure STAC catalogs is by organizing collections and items according to the STAC core specification, utilizing JSON and GeoJSON formats with proper RFC 8288 links to enable scalable geospatial data discovery and integration.

Can I use STAC to standardize metadata across diverse geospatial deployments?▼

Yes, you can use STAC to standardize geospatial metadata across diverse deployments. It ensures consistent discovery, validation, and interoperability for catalogs, collections, and items by conforming to the STAC core specification.
