> perhaps I have missed some basic info in some of the gshhs discussion, but I have a problem that islands seem to disappear when using cgmap_gshhs (newest library release of data and procedures). This is a code example. There should be lots of small islands here. Am I doing something wrong?

This seems to be a problem in calculating the area of the polygon
(always turning out to be 0). I have to do something else right now, but
I'll get back to this when I can.
