Is it possible to split multipolygon into smaller polygons?

Question

i have a multipolygon geometry like this: Gray area is the area where is no rivers, roads, villages and etc.

I need somehow to split this geometry to smaller polygons, to gray ones. So, i would like to ask if it is possible and how i could do that. Thanks.

What is your implementation/framework you are using to display/handle you ploygons? — Brett Walker, May 23 '15 at 09:34
Geometry in the picture is a result of two layers symmetrical difference. Therefore, it is a single geometry object. Although, i think @Brett Walker's answer should be what i needed. I am going to check his suggestion. — Vytaus, May 23 '15 at 09:56

Depending upon the implementation you are using, a multi-polygon is a collection of polygons. If you can obtain a list of the polygons comprising the multi-polygon via you implementation's API then you are a large way to doing what you need.

Thanks, I have tried casting geometry to MultiPolygon type and then i was able to retrieve list of polygons. – Vytaus May 23 '15 at 10:04
