OGC Main

The bounding box JSON object describes a simple spatial extent of a resource. For OGC API’s this could be a feature, a feature collection or a dataset, but it can be used in any JSON resource that wants to communicate its rough location. The extent is simple in that the bounding box does not describe the precise location and shape of the resource, but provides an axis-aligned approximation of the spatial extent that can be used as an initial test whether two resources are potentially intersecting each other.

A GeoJSON object

The bbox query parameter provides a simple mechanism for filtering resources based on their location. It selects all resources that intersect a rectangle (map view) or box (including height information).

The bbox-crs query parameter can be used to assert the coordinate reference system that is used for the coordinate values of the bbox parameter.

Web linking is used to express relationships between resources. The JSON object representation of links described here is used consistently in OGC API’s.

This Building Block defines a data type allowing schemas and profiles to use string base type for a full IRI/URI or a CURIE (with or without a prefix). This common pattern is complex to implement, and this Building Block makes it easy to implement consistently where-ever need.

A feature. Every feature is a sub-resource of an OGC Collection.

A JSON-FG compliant web link with mandatory annotation of link role and optional conformance information to describe target resource. Compliant with profile resource descriptor model.
