Version: 1.0.1
The features in an OGC Collection.
This resource supports spatial filtering with the bbox parameter, temporal filtering with the datetime parameter.
To avoid overloading clients and servers, both clients and servers can limit the maximum number of features in a representation of the resource. In this case, paging is supported to provide access to all the features in the collection that match the specified filter conditions.
