If you want to draw a Landscape Map for each object in different backgrounds (such as snow and grass), it is a redundant resource and a waste of space! Make it transparent and put it on the top, because the transparent effect is automatically displayed and the scenery is not better. In fact, this is generally something that everyone can think.

subclass. RasterMap is a subclass of MapLayerContainer and can be used to manage multiple map layers.

This article is from E liangshi Yiyou. Today's Mind Map course teaches you how to create layers and categories. Basic sequence ideas in any mind map are the simplest and most obvious sequence generators. They are all key concepts and contain the largest number of associations.

In Map 3D, you can use APIs to connect to various data sources such as SHP and Oracle. If you are not familiar with this process, refer to the BuildMap example in Map 3D ObjectARX SDK, however, BuildMap does not demonstrate how to disconnect from these data sources. If you have read the BuildMap implementation code, you will find that connecting to the data source is actually the process of creating the Fea
