Tin生成等高线

private void Tin2Contour (ITin pTin, IFeatureClass pFeatureClass)

{

  ITinSurface pTinSurface = pTin as ITinSurface;

  //不要启动编辑,因为这个接口会在要素类中添加字段 
  pTinSurface.Contour(0, 2, pFeatureClass, "Height", 0);

}

private void 等高线ToolStripMenuItem_Click (object sender, EventArgs e)

{

  ITinLayer pTinLayer = GetTINLayer (@"E:\arcgis\Engine\IDW数据\dvtin");

  IFeatureClass pFeatureClass = GetFeatureClass (@"E:\arcgis\Engine\IDW数据", "TinContour");

  IFeatureLayer pFeatLayer = new FeatureLayerClass ();
  pFeatLayer.Name = "等高线";

  pFeatLayer.FeatureClass = pFeatureClass;
  axMapControl1.Map.AddLayer (pFeatLayer as ILayer);
