Message	Sometimes in ArcView 9.3 when I attempt to calculate the area (in hectares) of polygons in a layer - using 'calculate geometry' in the attributes table - the area is returned but it is less than the actual area by a factor of 1 million. The data view and layer are both in a UTM coordinate system (Map Grid of Australia, GDA94). Has anyone had the same problem?
