I get the multypoligon from webservice and I try to calculate area for that poligon with the following code:
var poly = new OpenLayers.Geometry.MultiPolygon(poligon);
var area = geom.getArea();
But that returns me area in square degrees, our projection is EPSG:3243 I was try to use function
OpenLayers.Layer.SphericalMercator.forwardMercator
But that didn't help me alot, is there any other solution or some other hint?
Cheers!
