Islands and lakes

Syrett Global Mapper UserTrusted User

I have two datasets dating back to the 90s or so, depicting lakes and islands in Canada. (One shapefile for islands, one for lakes, mutually exclusive.) I would love to be able to punch the islands out of the lakes, because I'm creating a map in Illustrator that will have a relief background image, which I want to "show through" the islands. GM can subtract islands from *one* background object very nicely, but in this situation there are hundreds of lakes. Suggestions? Thanks!!
