How to add a terrain dataset as an elevation layer to ArcGlobe

Steps:

1. Click the Add Data button on the Standard toolbar.
2. Click the Look in drop-down arrow and navigate to the folder that contains the terrain dataset.
3. Click the terrain dataset.
4. Click Add.

Note:

It is recommended to convert the terrain dataset or a portion of the terrain dataset that you want to work with in ArcGlobe to a raster dataset using the Terrain To Raster 3D Analyst geoprocessing tool. This conversion is to improve performance as a terrain will be rasterized on-the-fly in ArcGlobe.
