   $box as cts:box,
   [$options as xs:string*]
) as cts:region


Construct a polygon from a box.

box A cts box that defines the polygon to be approximated.
options Options with which you can customize this operation. The following options are available:
Use the given coordinate system. Valid values are wgs84, wgs84/double, etrs89, etrs89/double, raw and raw/double. Defaults to the governing coordinating system.
Use the coordinate system at the given precision. Allowed values: float and double. Defaults to the precision of the governing coordinate system.

Usage Notes

It is recommended to use this function for queries, as box geometry matching cannot be optimized. Convert boxes to polygons before passing them in as arguments to your queries to get better performance.
