ITinSurface Interface

Tin 的表面分析得益于 ITinSurface 接口，而 ITinSurface 继承了 ISurface 接口，我们知道空间分析和 3D 分析在栅格表面分析有部分重合，但是 Tin 的表面分析只能在 3D 分析下进行.Tin 是一个用来模拟地表的组件类以便进行相应的分析。

打开Tin

public ITinLayer GetTINLayer (string pPath) //打开TIN文件

{

  ITinWorkspace pTinWorkspace;
  IWorkspace pWS;

  IWorkspaceFactory pWSFact = new TinWorkspaceFactoryClass ();
  ITinLayer pTinLayer = new TinLayerClass ();

  string pathToWorkspace = System.IO.Path.GetDirectoryName (pPath);
  string tinName = System.IO.Path.GetFileName (pPath);

  ITin pTin;

  pWS = pWSFact.OpenFromFile (pathToWorkspace, 0);
  pTinWorkspace = pWS as ITinWorkspace;

  if (pTinWorkspace.get_IsTin (tinName))

  {

    pTin = pTinWorkspace.OpenTin (tinName);
    pTinLayer.Dataset = pTin;
    pTinLayer.ClearRenderers ();

    return pTinLayer;

  } else

  {

    MessageBox.Show ("该目录不包含Tin文件");
    return null;

  }

}

或者下面的代码

ITinAdvanced2 pTin = new TinClass ();
pTin.Init (@"E:\arcgis\Engine\IDW数据\dvtin");

ITinLayer pTinLayer = new TinLayerClass ();
pTinLayer.Dataset = pTin;

axMapControl1.Map.AddLayer (pTinLayer as ILayer);
