类名称：Point
方法名：altitude

Point.altitude介绍

[英]Optionally, the coordinate spec in GeoJson allows for altitude values to be placed inside the coordinate array. #hasAltitude() can be used to determine if this value was set during initialization of this Point instance. This double value should only be used to represent either the elevation or altitude value at this particular point.
[中]或者，GeoJson中的坐标规范允许将高度值放置在坐标数组中#hasAltitude（）可用于确定此值是否在该点实例的初始化过程中设置。此双精度值仅用于表示此特定点的高程或高度值。
