geom.MultiPolygon()

class geom.MultiPolygon(coords)
Arguments

  • coords (Array) – Coordinates array.

Create a new multipolygon geometry. The items in the coords array may be polygon coordinates or geom.Polygon() objects.

Example Use

Sample code to new multi-polygon:

>> var {Polygon, MultiPolygon} = require("geoscript/geom");
>> var p1 = Polygon([
..   [[-180, -90], [-180, 90], [180, 90], [180, -90], [-180, -90]],
..   [[-90, -45], [-90, 45], [90, 45], [90, -45], [-90, -45]]
.. ]);
>> var p2 = Polygon([
..   [[-60, -30], [-60, 30], [60, 30], [60, -30], [-60, -30]]
.. ]);
>> var mp = MultiPolygon([p1, p2]);

Alternate method to create the same geometry as above:

>> var mp = MultiPolygon([
..   [
..     [[-180, -90], [-180, 90], [180, 90], [180, -90], [-180, -90]],
..     [[-90, -45], [-90, 45], [90, 45], [90, -45], [-90, -45]]
..   ], [
..     [[-60, -30], [-60, 30], [60, 30], [60, -30], [-60, -30]]
..   ]
.. ]);
