admin.databaseGeospatialRegionPathIndex(
   pathexpr as String,
   coordinate-system as String,
   geohash-precision as Number,
   invalid-values as String,
   [units as String?]
) as element(db.geospatialRegionPathIndex)

Summary

This function constructs a geospatial region path index specification.

Parameters
pathexpr The path expression for the index. The path should return true from cts:valid-index-path.
coordinate-system The coordinate system. Must be one of wgs84, wgs84/double, etrs89, etrs89/double, raw, raw/double.
geohash-precision Specify the precision of the geohashes to use in the index. Higher numbers result in a more precise index and faster queries, at the expense of increased index size and slower ingestion speed. Value must be between 2 and 6 (inclusive) if using a single precision coordinate system; between 3 and 6 if double precision. Ignored for raw and raw/double coordinate systems.
invalid-values Specify how to handle values that cannot be parsed as regions. Must be one of: reject or ignore.
units Measure distance and the radii of circles in the specified units. Allowed values: miles (default), km, feet, meters.

Example

const admin = require('/MarkLogic/admin.xqy');
admin.databaseGeospatialRegionPathIndex(

    "//kml.LinearRing/kml.coordinates", "wgs84", 2, "reject", "miles")
 //A geospatial region path index specification
