You can also use the 'area_thresh' keyword to control the minimum size of coastline features that are drawn. area_thresh=1000000 makes the Great Lakes disappear, at the expense of making all the islands except Greenland disappear too. If that's unacceptable, you'll have to do as Scott suggests and create a shapfile without the lakes. -Jeff ------------------------------------------------------------------------------ Come build with us!
