geogml:to-gml( $region as cts:region*, [$gml-namespace as xs:string] ) as element()*
Summary
Construct GML elements from cts:region values.
| Parameters | |
|---|---|
| region | Zero or more cts:region values. |
| gml-namespace | A GML namespace URI that indicates the GML version of the output elements. Defaults to GML v3.2 (http://www.opengis.net/gml/3.2). |
Example
xquery version "1.0-ml";
import module namespace geogml = "http://marklogic.com/geospatial/gml"
at "/MarkLogic/geospatial/gml.xqy";
geogml:to-gml(
cts:polygon((
cts:point(5.0,1.0), cts:point(8.0,1.0),
cts:point(8.0,6.0), cts:point(5.0,7.0)
))
)
==> A GML v3.2 polygon element similar to the following:
<gml:Polygon gml:id="n9a22cfd1385cc751" srsName="ML:wgs84"
xmlns:gml="http://www.opengis.net/gml/3.2">
<gml:exterior>
<gml:LinearRing>
<gml:posList srsDimension="2">5 1 8 1 8 6 5 7 5 1</gml:posList>
</gml:LinearRing>
</gml:exterior>
</gml:Polygon>
Example
xquery version "1.0-ml";
import module namespace geogml = "http://marklogic.com/geospatial/gml"
at "/MarkLogic/geospatial/gml.xqy";
(: Explicitly specify the GML namespace URI :)
