GlobeControl中设置图层基本高程

ILayer pLayer = new MapOperationClass().GetLayer(MyGlobe, "市区道路L");

IGlobeDisplayLayers pGlobeDisplayLayers = MyGlobe.GlobeDisplay as IGlobeDisplayLayers;

IGlobeLayerProperties pGlobeLayerProperties = pGlobeDisplayLayers.FindGlobeProperties(pLayer);

IGlobeHeightProperties pGlobeHeightProperties = pGlobeLayerProperties.HeightProperties;

pGlobeHeightProperties.BaseOption = esriGlobeLayerBaseOption.esriGlobeLayerBaseSelf;

pGlobeHeightProperties.Offset = slider1.Value+500;       // 500为与地球相叠加

pGlobeHeightProperties.Apply(MyGlobe.Globe, pLayer);

MyGlobe.GlobeDisplay.RefreshViewers();
