[udig-devel] Area of a polygon?

[tony.roth@xxxxxx]

Hi list,

how to get the area of a polygon?

 

I draw a polygon roughly covering egypt and both polygon.getArea() and Areafunction.getArea(polygon) return something about 91.4. But what? The Wikipedia tells me that egypt has an area of ~1,000,000km² or 386,000 sq mi. Ok, my polygon is not perfect but 91,4 is neither km² nor sq mi.

 

Where's my fault?
