->GEOJSON
geo
The ->GEOJSON function translate the given GeoShape into a GeoJSON.
The resulting GeoJSON is a string representing a MultiPolygon geometry. By default, it defines the boundaries of the covered areas and any holes it these areas, if any.
It is also possible for this function to return a GeoJSON representing all the cells in the GeoShape.
GeoJson could be visualized on the map, if you let a special object on the map. See example.
