MITAB doesn't expose any area calculation function (well, I don't remember putting one in or seeing one added), but polygon area calculations are easy to implement. For an example, see question "HOW DO I FIND THE AREA OF A 3D POLYGON?" in the comp.graphics.algorithms FAQ at http://www.faqs.org/faqs/graphics/faq/. The first part of the answer deals with 2-D polygon area calculations. Daniel -- Daniel Morissette http://www.mapgears.com/ Yahoo!
