Query parameters

bboxnumber[] · min: 4 · max: 6Optional

The optional bbox parameter specifies a supported bounding box. Only features that have a geometry that intersects the bounding box are selected. The bounding box is provided as four comma-separated numbers: Lower left corner, coordinate axis 1 (e.g. min x axis) Lower left corner, coordinate axis 2 (e.g. min y axis) Upper right corner, coordinate axis 1 (e.g. max x axis) Upper right corner, coordinate axis 2 (e.g. max y axis)The default 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.

Example: [-0.183678,51.474968,-0.068321,51.540143]

bbox-crsstring · enumOptional

The coordinate reference system of the bbox parameter. It must be a 2D coordinate reference system supported by the collection. Default is WGS84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/CRS84).

Possible values:

crsstring · enumOptional

The coordinate reference system of the response geometries. It must be a coordinate reference system supported by the collection. Default is WGS84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/CRS84).

Possible values:

datetimestringOptional

Either a local date, a date-time with UTC time zone (Z) or an open or closed interval. Open ranges in time intervals at the start or end are supported using a double-dot (..) or an empty string for the start/end. Date and time expressions adhere to RFC 3339. Examples:A date-time: '2021-12-12T23:20:50Z'A closed interval: '2021-12-12T00:00:00Z/2021-12-18T12:31:12Z'Open intervals: '2021-12-12T00:00:00Z/..' or '../2021-12-18T12:31:12Z'An interval until now: '2018-02-12T00:00:00Z/..' or '2018-02-12T00:00:00Z/'Selects features that have a temporal property that intersects the value of the parameter.

Example: 2018-02-12T00:00:00Z/..

limitinteger · min: 1 · max: 100Optional

The optional limit parameter limits the number of items that are presented in the response document. Minimum = 1. Maximum = 100. Default = 100.

offsetintegerOptional

The optional offset parameter skips past the specified number of features in the collection. Minimum = 0. Default = 0.

filterstringOptional

The optional filter parameter is a filter expression in CQL format which is applied when retrieving resources to determine which resources are included in a result set.

filter-crsstring · enumOptional

Specify which of the supported CRSs to use to encode geometric values in a filter expression. It must be a 2D coordinate reference system supported by the collection. Default is WGS84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/CRS84).

Possible values:

filter-langstring · enumOptional

The optional filter-lang parameter is the specific language used for the filter parameter. Default = cql-text

Possible values:
