void JunSuMFCDialogDlg::OnFileImporttif()
{
    // TODO: 在此添加命令处理程序代码
    UGWorkspace* pWorkspace = (UGWorkspace*)m_pMapControl->GetMapEditWnd()->m_mapWnd.m_Map.GetWorkspace();
    UGDataExchange exchange = UGDataExchange();
    UGDataSource* ds = pWorkspace->GetDataSource(0);
    if (!ds)
    {
        return;
    }
    int issu = exchange.AttachDataSource(ds);
    
    UGGTiffImportParams importparams = UGGTiffImportParams();

    UGString NAME = ds->GetUnoccupiedDatasetName(_U("TIF"));
    importparams.SetDestDTName(NAME);
    importparams.SetFilePathName(_U("C:\\Users\\86182\\Desktop\\c++导入数据测试数据\\data\\tif\\dsm_4.tif"));
    UGint ii = importparams.GetFileType();
    int ss = UGExchangeParamsManager::IsValidImportParams(ii, importparams);

    UGint issucceed = exchange.Import(importparams);

    if (issucceed == 1)
    {
        
        UGDatasetRaster* dataset = (UGDatasetRaster*)ds->GetDataset(NAME);
        dataset->BuildPyramid(false);
        UGLayer* layer = m_pMapControl->GetMapEditWnd()->m_mapWnd.m_Map.m_Layers.AddDataset(dataset, true);
        m_pMapControl->GetMapEditWnd()->m_mapWnd.m_Map.SetViewBounds(layer->GetBounds(), true);
        m_pMapControl->Refresh();
    }
    else
    {
        //QMessageBox::information(NULL, QString::fromLocal8Bit("导入shp"), QString::fromLocal8Bit("导入失败"), QMessageBox::Close, QMessageBox::Close);
