类名称：GeoCoding

GeoCoding介绍

[英]The GeoCoding interface provides geo-spatial latitude and longitude information for a given X/Y position of any (two-dimensional) raster.

Note: New geo-coding implementations shall implement the abstract class AbstractGeoCoding, instead of implementing this interface.

All GeoCoding implementations should override the Object#equals(Object) and Object#hashCode() methods.
[中]GeoCoding界面为任何（二维）光栅的给定X/Y位置提供地理空间纬度和经度信息。
注：新的地理编码实现应实现抽象类AbstractGeoCoding，而不是实现此接口。
所有GeoCoding实现都应该重写Object#equals（Object）和Object#hashCode（）方法。
