    QueryCircle:
      name: circle
      description: Circle coordinates and radius distance in the format `<X>,<Y>,<RADIUS>`.  The `X,Y` coordinates must be consistent with the `srid` (`4326` for longitude/latitude by default).  The `<RADIUS>` defines the distance (in default or `distanceUnits`-specified units) from the defined point.  Limits to objects within or intersecting the area so defined.  No more than one of `bbox`, `polygon`, `circle`, and `corridor` may be used in one request.  Requests with circle definition of area that crosses antimeridian will fail.  The larger the defined area, the more its shape on projected map will differ from true circle on spherical coordinates.  Maximum allowed <RADIUS> is 400nm (and equal lengths for different `distanceUnits`).

Must provide between 3 and 40 coordinates.  If the last `X,Y` does not match the first `X,Y`, the first `X,Y` is copied to the end to close the polygon.  Limits to objects within or intersecting the area so defined.  No more than one of `bbox`, `polygon`, `circle`, and `corridor` may be used in one request.  Requests with polygon definition of area that crosses antimeridian will fail or give unexpected results.
