Remarks

A basemap layer is a user-defined group of layers that are drawn continuously during navigation. BasemapLayer implements IGroupLayer, and in many ways it behaves the same as GroupLayer. BasemapLayer draws with a high-performance drawing engine that can significantly improve the display speed and responsiveness of your map. ArcMap is the primary consumer of BasemapLayer; however, the MapControl and ArcReader also have the same performance benefits when working with BasemapLayer. Components using the output pipeline of the ArcGIS 2D drawing engine, such as ArcGIS for Server and the 3D applications drawing draped content, will not see a benefit from using BasemapLayer. Optimized map services in ArcGIS for Server use the same drawing engine as BasemapLayer and should be used to achieve fast map services.
