geojson.parseGeojson

geojson.parseGeojson(
   $geojson as objectNode()[]
) as Sequence

Summary

Convert GeoJSON object nodes into cts:region values.

Parameters
$geojson Zero or more JSON object nodes conforming to the GeoJSON specification.

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 returned Sequence contains cts:region values.

Example

var geojson = require('/MarkLogic/geospatial/geojson.xqy');

geojson.parseGeojson(
  { type: 'Polygon', 
    coordinates: [
      [[1.0, 5.0], [1.0, 8.0], [6.0, 8.0], [7.0, 5.0], [1.0, 5.0]]
  ] }
)

==> A Sequence that contains a cts.polygon equivalent to the input region.
