Examine default layers in ArcGloba and add more layers
Segment 1 of 7

Navigating in ArcGlobe lets you explore your data and teaches you how to accomplish fundamental tasks that you’ll use later. ArcGlobe starts and its default layers are loaded. Notice which layers are loaded in the globe by looking at the list in the table of contents.
ArcGlobe categorizes layers according to their type. Layers are classified as elevation, draped, or floating. Elevation layers are raster sources with height information. They give the globe surface terrain. Draped layers are features or rasters that use the elevation layers as a source of their base heights. These layers appear draped over the globe surface. Floating layers are features or rasters that float independently of the terrain surface. They appear offset from other layers, either draped on discrete surfaces or set to some constant elevation. Note the way the default layers are categorized. Notice the default layers listed in the Type page of the ArcGlobe table of contents. Both layers are draped layers and, therefore, appear draped on the globe surface.
Default layers serve as a background to any data that you want to add to ArcGlobe. The image layers are added to ArcGlobe as draped layers.
