consist of multiple feature collections. A feature collection is often a
collection of features of a similar type, based on a common schema.

Only features that have a temporal property that intersects the value of
`datetime` are selected.

server whether only a single temporal property is used to determine
the extent or all relevant temporal properties.'

bbox:
name: bbox
in: query
description: 'Only features that have a geometry that intersects the bounding box are selected.
The bounding box is provided as four or six numbers, depending on whether the
coordinate reference system includes a vertical axis (elevation or depth):
* Lower left corner, coordinate axis 1
* Lower left corner, coordinate axis 2
* Lower left corner, coordinate axis 3 (optional)
* Upper right corner, coordinate axis 1
* Upper right corner, coordinate axis 2
* Upper right corner, coordinate axis 3 (optional)
The coordinate reference system of the values is WGS 84 longitude/latitude
(http://www.opengis.net/def/crs/OGC/1.3/CRS84) unless a different coordinate
reference system is specified in the parameter `bbox-crs`.
For WGS 84 longitude/latitude the values are in most cases the sequence of
minimum longitude, minimum latitude, maximum longitude and maximum latitude.
However, in cases where the box spans the antimeridian the first value
(west-most box edge) is larger than the third value (east-most box edge).
If a feature has multiple spatial geometry properties, it is the decision of the
server whether only a single spatial geometry property is used to determine
the extent or all relevant geometries.'

description: "The response is a document consisting of features in the collection. \nThe features included in the response are determined by the server \nbased on the query parameters of the request. To support access to \nlarger collections without overloading the client, the API supports \npaged access with links to the next page, if more features are selected \nthat the page size.\n\nThe `bbox` and `datetime` parameter can be used to select only a \nsubset of the features in the collection (the features that are in the \nbounding box or time interval). The `bbox` parameter matches all features \nin the collection that are not associated with a location, too. The \n`datetime` parameter matches all features in the collection that are \nnot associated with a time stamp or interval, too.\n\nThe `limit` parameter may be used to control the subset of the \nselected features that should be returned in the response, the page size.\nEach page may include information about the number of selected and \nreturned features (`numberMatched` and `numberReturned`) as well as \nlinks to support paging (link relation `next`)."
