Method Summary

double	getArea() The operation "area" shall return the area of this GM_GenericSurface.
GM_Envelope	getEnvelope() returns the bounding box of the surface
double	getPerimeter() returns the length of all boundaries of the surface in a reference system appropriate for measuring distances.

Method Detail

getPerimeter

public double getPerimeter()

returns the length of all boundaries of the surface in a reference system appropriate for measuring distances.

getArea

public double getArea()

The operation "area" shall return the area of this GM_GenericSurface. The area of a 2 dimensional geometric object shall be a numeric measure of its surface area Since area is an accumulation (integral) of the product of two distances, its return value shall be in a unit of measure appropriate for measuring distances squared.

getEnvelope

public GM_Envelope getEnvelope()

returns the bounding box of the surface
