In most scenes, the elevation surface represents the ground: the topography of the earth's surface. Map layers will use the elevation values of the high-resolution layer where they are available. The Kelburn suburb at a resolution of 1 meter. In this section, you'll add a second ground elevation layer. For example, a high-resolution layer may provide elevation values for a small area of interest, while a low-resolution layer provides elevation values for surrounding areas. You can add more than one layer to an elevation surface. WorldElevation3D/Terrain3D is a fairly low-resolution surface. Surfaces that cover large areas generally have lower resolution (less detail) than surfaces that cover small areas. The resolution of the surface-the amount of elevation detail it contains-may be high or low. In the next section, you'll add another elevation surface to the scene to provide more detailed elevation values for the Kelburn suburb.Īdd another elevation surface to the sceneĪn elevation surface is a raster or TIN dataset (or a web elevation layer created from a raster dataset) that stores elevation values for a continuous geographic area. Alternatively, use the on-screen navigator in the lower left corner of the scene.
In the Contents pane, the map layers have been copied to the scene. They use the WGS 1984 geographic coordinate system. Global scenes don't support projected coordinate systems. Local scenes support projected coordinate systems. You can view any scene as a global scene or a local scene by clicking Global or Local in the View group on the View tab.
