Display KMZ loaded file is not the same as original file in Google Map API v3

Question

I have loaded a KMZ file in Google Map API v3 which has detail polygons but the system doesn't show detail polygons and just display one polygon.

Original KMZ file in Google Earth:

Displayed KMZ file in Google Map API v3:

KMZ File

Does anybody know how can I solve this problem?

Thanks in advance!

Answer 1

All your polygons have the same winding direction.

To make holes in a polygon the innerBoundaryIs needs to wind in the opposite direction of the outerBoundaryIs that contains it.
