ArcGIS Editor for OSM 10.6.x Desktop
OpenStreetMap ArcGIS编辑器允许你使用ArcGIS工具为OpenStreetMap数据工作。这个桌面工具ArcMap 10.6.x允许你加载OpenStreetMap数据并将其存储在地理数据库中 。你可以使用ArcMap熟悉的编辑环境的创建,修改,做网络分析,或者更新数据。一旦您完成编辑后,你可以回到编辑修改OSM使它们提供给所有相关用户。
此下载有两个设置。一是利用ArcGIS 10.6兼容。X,其他兼容ArcGIS 10.6与64位背景处理安装;即,它是在“为OpenStreetMap 10.6 ArcGIS编辑(64位)”的文件夹。安装后,推出ArcMap,你应该看到一个“工具箱”安装你的系统工具箱OpenStreetMap在目录浏览窗口。有关如何使用工具的文档。
注意:如果你在过去使用这种工具,一定要看到变化的发行说明,特别是关于数据上传回OSM的工作流程。

XMIExprt.dll
Visio 2003 Professional Edition和ArcGis关联的安装方法
1.复制ArcGIS安装文件夹(\Program Files\ArcGIS\CaseTools\Utilities)下的ESRI XMI Export.vsl到Visio 2003安装文件夹(\Program Files\Microsoft Office\Visio11\2052)下。
2.复制XMIExprt.dll到Visio 2003安装文件夹(\Program Files\Microsoft Office\Visio11\DLL)下。
3.启动Visio 2003 Professional
4.选择 工具——〉选项,在弹出的“选项”对话框中,选择“高级”标签,在高级标签中点击“文件路径”按钮,在弹出的“文件路径”对话框中,点击“加载项”右边的“ ”按钮,选择Visio 2003安装路径(Program Files\Microsoft Office\Visio11\)下的2052文件夹,单击“确定”按钮关闭“文件路径”和“选项对话框”。
5.选择工具——〉选项,在弹出的“选项”对话框中,选择“安全性”标签,在该面板中点击 按钮,在弹出的安全性对话框中将“安全级”标签下的安全性级别设置为“低”。
6.关闭Visio 2003。
7. 重新启动Visio 2003,打开ArcGIS安装文件夹(\Program Files\ ArcGIS\ CaseTools\Uml Models)下的模板ArcInfo UML Model (Visio 2003).vst,Visio就是通过ESRI提供的该模板才与ArcGIS关联起来的。也只有在该模板下绘制的UML模型才能最终导成数据库模式。
XMIExport.dll就可以执行该文件后得到
如果你是visio 2002 需要用XMIExport.dll
