Q: A Polygon is constructed in the iClient for Javascript. How do you know the sphere surface area and perimeter on the geographic coordinate map?

A: You can use getGeodesicArea and getGeodesicLength methods of the SuperMap.Geometry.Collection which is the parent class of SuperMap.Geometry.Polygon to get the approximate surface area and perimeter.
