Hello,

I'm curious how geomason handles geographic references. I'm importing a 
shapefile with  polygons in the WGS84 reference system. All the points 
have values like 52.03N 7.63E. When I measure the polygon area with a 
gis then I get different values than using the getArea on the polygons 
geometry.
Even when I accept that getArea gives me the area in degrees it isn't 
the same mē after I convert the value.

I found nothing in the api or the other doc sources where this part is 
described.
Now I'm not sure what to do. Am I making a mistake or do I miss something?

thanks in advance,
Norman Langner
