浮雕地图

创建三维浮雕地图，将数据覆盖在地形上，自定义阴影和照明效果

浮雕地图通过阴影和光照效果来表现地形或其他地表纹理。使用这些函数可从网格化数据创建地形晕渲图，调整阴影和光照效果，夸大地形特征，并应用颜色图。您还可以将数据覆盖在高程图上。

Add Light Source to Terrain Map
Add a light source to a terrain map, then set surface reflectance properties.
Surface Relief Shading
A shaded-relief map models illumination over a surface to highlight the texture of the surface.
Colored Surface Shaded Relief
This example shows how to illuminate surface texture over colored elevation data using shaded relief computations.
Relief Mapping with Light Objects
This example shows how to illuminate surface texture over colored elevation data using a light source.

Drape Data on Elevation Maps
You can drape satellite data over a grid of elevations in order to see the topography of the surface.
Drape Geoid Heights over Topography
This example shows how to drape the figure of the Earth, shown as an attribute (color) data grid, on topographic relief.
