ArcGIS离线数据编辑【一】

ArcGIS GeoDataBase支持离线数据编辑，通过与ArcPad、ArcMobile等移动GIS（可用于外业数据采集）相配合为国土、测绘、管线、规划等众多行业提供一套完整的数据更新解决方案。
离线编辑：先将要更新的数据从数据库下载到本地，然后通过其他的软件或工具对下载的数据进行编辑，最后上传到数据库完成对服务器数据的更新。
本篇主要说明功能本身的实现，至于复合数据类型（拓扑、几何网络、…）的处理、SDE版本编辑冲突等问题将在后续篇章中陆续介绍。
数据下载时在当前数据访问的SDE版本下创建一个临时的子版本，在上传更新时提交并回收子版本。
主要代码如下：

 public void DataCheckOut(IMap pMap, enumDataCheck eDataCheck,IGeometry pGeometry, bool bUserZone)

        {

            try

            {

               string sPath = “”;

               IWorkspaceFactory pWorkspaceFactory = null;

               if (eDataCheck == enumDataCheck.GDB)

               {

                   pWorkspaceFactory = newESRI.ArcGIS.DataSourcesGDB.FileGDBWorkspaceFactoryClass();

                   SaveFileDialog pDialog = new SaveFileDialog();

                   pDialog.Filter = “数据库名(*.*)|*.*”;

                   if (pDialog.ShowDialog() != DialogResult.OK) return;

                   sFile = pDialog.FileName;

                   sPath = sFile.Substring(0, sFile.LastIndexOf(“\”) + 1);

                   sFile = sFile.Substring(sPath.Length);

               }

               else
