Requirement 1

/req/tiles/multitiles/mtc-bbox-definition

A

The operation SHALL support an optional parameter bbox to filter the area where tiles will be retrieved with the following characteristics (shown as OpenAPI Specification 3.0 fragment):

    name: bbox
    in: query
    description:
      'Only elements 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 by another parameter in the API (e.g `bbox-crs`).'
    required: false
    schema:
      type: array
      minItems: 4
      maxItems: 6
      items:
        type: number
        format: double
    style: form
    explode: false

B

A TileMatrixSet definition points to a CRS. The coordinates of the bbox SHALL be in the CRS as specified in the definition of the TileMatrixSet identified by the tileMatrixSetId

C

If the ´bbox´ parameter is not specified, the server SHALL assume the whole extent of the tiles is requested.
