Functions

geoMultiPolygon()

Build a GeoJSON MultiPolygon geometry.

geoMultiPolygon(array<string|int, mixed>|string $polygons) : string

This helper wraps the ArangoDB AQL function GEO_MULTIPOLYGON(polygons) which constructs a valid GeoJSON MultiPolygon from an array of polygons. Each polygon is itself an array of linear rings of [longitude, latitude] pairs, following the GeoJSON longitude-first convention.

Example AQL usage:

GEO_MULTIPOLYGON([ [ [ [0,0],[1,0],[1,1],[0,0] ] ] ])
Parameters
$polygons : array<string|int, mixed>|string

An array of polygons, or an AQL expression.
