->GEOJSON

geo

The ->WKB function converts a WKT STRING, WKB BYTES, a GML **STRING, a KML STRING or a SHAPE to a GeoJSON STRING.

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.

->GEOJSON is available since version 2.4.1.
