球体显示

在三维球体上绘制数据，应用高分辨率或自定义底图，应用自定义地形

使用球体显示函数，可将三维数据可视化呈现于地形、高缩放级别的底图及其他表面之上。交互式浏览球体显示，或通过设置相机位置和旋转角度来程序化地改变视角。

使用地理球体显示飞行轨迹等数据，这些数据可叠加在地形和底图之上。您可以针对大地水准面、地形或 WGS84 参考椭球绘制高度数据。有关详细信息，请参阅 geoglobe。
使用球体投影法将海面温度和风速等数据以表面形式显示。您还可以使用球体投影来建模各种参考椭球体，包括非地球行星体的椭球体。有关详细信息，请参阅 globe。

Access Basemaps and Terrain for Geographic Globe
The geographic globe plots data over basemaps and terrain. Download some of these basemaps or add custom basemaps and terrain.
Use Basemaps in Offline Environments
Display data over basemaps when MATLAB^® has temporary or no internet access.
Create Interactive Basemap Picker
Interactively change the basemap of a geographic globe by using a drop-down menu.
从正高推算椭球高
通过使用正高和大地水准面模型，求解某点的椭球高。

Compute and visualize line-of-sight visibility of an aircraft from a ground location over terrain.

Simulate an unmanned aerial vehicle (UAV) flight using synchronized geographic axes and a geographic globe.

Define an L-band radar system in the presence of heavy clutter and visualize its three-dimensional vertical coverage over terrain.
