ArcObjects Library Reference (GlobeCore)

IGlobeHeightProperties Interface

Provides access to members that manipulate the height properties of a globe layer. Note: the IGlobeHeightProperties interface has been superseded byIGlobeHeightProperties2. 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

	Name	Description
	Apply	Apply to the corresponding layer.
	ApplyFeatureProperties	Obtain feature geometry with the correct properties.
	BaseLayer	The base layer.
	BaseLayerName	The base layer name persisted.
	BaseOption	The base option.
	ElevationExpression	The elevation expression for features, in globe units.
	ElevationExpressionString	The elevation expression string for features, in globe units.
	ExtrusionExpression	The extrusion expression object.
	ExtrusionExpressionString	The extrusion expression string.
	ExtrusionType	The extrusion type.
	HasElevationValues	Indicates whether the feature layer has elevation values.
	Offset	The constant elevation offset in meters.
	UseElevationValues	Indicates whether elevation values in the feature layer are used.
	ZFactor	The z factor.

[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();
}
