IGlobeHeightProperties Interface

Provides access to members that manipulate the height properties of a globe layer. Note: the IGlobeHeightProperties interface has been superseded by IGlobeHeightProperties2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

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

Members

[C#]

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();
