合并与修改地图

用 Show 合并地图并修改其选项.

取两个地图，每个都包含一个彩色多边形.

In[1]:=

spain = GeoGraphics[{GeoStyling[Red, Opacity[0.5]], Polygon[Entity["Country", "Spain"]]}]

Out[1]=

In[2]:=

italy = GeoGraphics[{GeoStyling[Green, Opacity[0.5]], Polygon[Entity["Country", "Italy"]]}]

Out[2]=

合并地图然后做些修，这里是加入了地理网格线.

In[3]:=

Show[spain, italy, GeoGridLines -> Automatic]

Out[3]=

进一步修改地图，现在来改变地理背景的样式.

In[4]:=

Show[spain, italy, GeoGridLines -> Automatic]; Show[%, GeoBackground -> "Satellite"]
