Description
The IGlobeHeightProperties interface can be used to manage the height properties of a data layer in globe.

The code below illustrates how we can use IGlobeHeightProperties set the base height of a draped layer, present in the TOC, to a raster elevation surface.
public void Drape_Layer_On_ElevationRaster(IGlobeDisplay pGlobeDisplay, ILayer pLayer)
{
IGlobeDisplayLayers pGlobeDispLyrs = (IGlobeDisplayLayers) pGlobeDisplay;
//Create elevation raster layer
IRasterLayer pElevLayer = new RasterLayerClass();
pElevLayer.CreateFromFilePath("C:\\temp\\elev_raster");
//Create and add the GlobeLayerProperties extension
//with the Type set to ElevationData
IGlobeLayerProperties pLyr_GlobeLayerProps = new GlobeLayerPropertiesClass();
pLyr_GlobeLayerProps.Type=esriGlobeDataType.esriGlobeDataElevation;
ILayerExtensions pLyrExt = (ILayerExtensions) pElevLayer;
pLyrExt.AddExtension(pLyr_GlobeLayerProps);
//Set the base option for pLayer to be esriGlobeLayerBaseLayer
//and its base layer to be pElevLayer
IGlobeLayerProperties pDrapeLyr_GlobeLayerProps;
pDrapeLyr_GlobeLayerProps = pGlobeDispLyrs.FindGlobeProperties(pLayer);
IGlobeHeightProperties pDrapeLyr_GlobeHeightProps;
pDrapeLyr_GlobeHeightProps = pDrapeLyr_GlobeLayerProps.HeightProperties;
pDrapeLyr_GlobeHeightProps.BaseLayer = pElevLayer;
pDrapeLyr_GlobeHeightProps.BaseOption=esriGlobeLayerBaseOption.esriGlobeLayerBaseLayer;
//Apply the height properties of the pLayer
pDrapeLyr_GlobeHeightProps.Apply(pGlobeDisplay.Globe, pLayer);
pGlobeDisplay.RefreshViewers();
