MarkLogic 9 Product Documentationgeojson.toGeojson
geojson.toGeojson( regions as cts.region[] ) as Sequence
Summary
Convert cts:region values into GeoJSON object nodes.
| Parameters | |
|---|---|
| regions |
Zero or more cts:region values to convert to GeoJSON.
|
Usage Notes
The GeoJSON Point node includes additional information that is not retained in the cts:point value. In particular, the altitude part of the point value will be dropped. Therefore two GeoJSON points at the same latitude and longitude with different altitude will nevertheless have equal cts:point values.
The return Sequence contains JSON object nodes
conforming to the GeoJSON representation.

Example
var geojson = require("/MarkLogic/geospatial/geojson");
geojson.toGeojson(
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 Sequence containing a JSON object node that represents a
GeoJSON polygon similar to the following:
{ "type": "Polygon",
"coordinates": [
[[1.0, 5.0], [1.0, 8.0], [6.0, 8.0], [7.0, 5.0], [1.0, 5.0]]
]
