geo functions (GEO)
The Geo module provides support for geospatial queries using GML, KML, GeoRSS/Simple, Metacarta or GeoJSON Geospatial markup.
To use this module in your Server-Side JavaScript code, include a
require statement similar to following line in your code:
var geo = require('/MarkLogic/geospatial/geospatial');
The library namespace prefix geo is not predefined
in the server.
