Enclosed is an example of a shapefile containing 1 polygon with a hole in it. It is taken from the 2000 Census data of Norfolk, VA.

Thanks, Mary ---------------------------------------------------------------------- >Comment By: James Macgill (jmacgill) Date: 2002-03-15 15:35 Message: Logged In: YES user_id=9731 Sorry this one has taken a while to fix. The area code was only calculating the area for the main part of the polygon. This has been fixed so that all parts are calulated, including holes. One odd thing with the sample though is that the first part of the polygon in the shapefile is the hole followed by the outer shell. This is why the area was negative as you were only getting the area of the hole. I'm not sure, but I think this may be illigal in shapefiles. Anyway, the code is now fixed and gives a +ve area. You can get the new code from cvs or download the nightly build from the files section of the sourceforge site. Let me know if there are any problems.
