geo.polygon

geo.polygon(
   polygon-or-points as Node[]
) as cts.polygon

Summary

Create a cts.polygon value from a sequence of point nodes in one of the supported markup vocabularies, such as KML or GML.

Parameters
polygon-or-points A sequence of nodes, each representing a vertex (point) of the polygon, or a polygon node. A polygon from one of the supported markup vocabularies represents the exterior polygon for those vocabularies that include both exterior and interior polygons in their representation.

Usage Notes

If you know the geospatial data format (GML, KML, etc.), it is more efficient to use the equivalent format-specific function.
