arcgis二次开发(addin)在三调中的运用(一)

首先小伙伴们，可以参考arcgis开发学习视频。

https://edu.csdn.net/course/detail/25535

最近有小伙伴，有这样的需求，在三调项目制作数据中遇到这样的问题。现在有一份很多的图斑shapefile数据，和一份行政村的shapefile数据。现在要做的工作是，将图斑中的数据每个图斑与行政村叠加，然后将与之相交的行政村的名字字段写到图斑的行政村字段中，如果有多个行政村，其中相交的面积超过一定的值，那么必须将该行政村作为有效值填入到图斑中。

一开始，我想使用python来实现，但想想使用arcpy在arcgis中拓扑分析比较弱，最后使用了c#来开发了这个工具。这里使用的arcgis addin的方式来开发这个工具。设计的思路是，利用图斑图层遍历所有的面，将每个面与图层行政村相交，然后计算出与图斑相交的每一个行政村的相交面积，如果面积大于一定的阈值，那么就取出该行政村的名称字段值填入到图斑的对应字段。

下面来看一下arcgis关于addin方面的开发。首先我使用的是visual studio2012和arcgis object10.2开发，关于安装visual studio和arcgis object大家可以参考相关的网络资料。下面来看一下具体的步骤。

来看一下，整个工程结构如下图所示。

这里要重写Button1里面的Onclick方法，这样才能与之对应响dockwindow

using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Framework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WinDockUpdateProperty
{
    public class Button1 : ESRI.ArcGIS.Desktop.AddIns.Button
    {
        public Button1() { 
        
        }

        protected override void OnClick()
        {
            IDockableWindowManager dockWindowManager = ArcMap.DockableWindowManager as IDockableWindowManager;

            if (dockWindowManager != null)
            {
                UID windowID = new UIDClass();

                windowID.Value = ThisAddIn.IDs.DockableWindow;
                IDockableWindow docWin = dockWindowManager.GetDockableWindow(windowID);
                if (docWin.IsVisible())
                {
                    docWin.Show(false);
                }
                else
                {
                    docWin.Show(true);
                }

            }
            ArcMap.Application.CurrentTool = null;
        }

        protected override void OnUpdate()
        {
            Enabled = ArcMap.Application != null;
        }
    }
}

 

下面来编写一下与本次操作有关的代码。基本上就是Arcengiene的二次开发，实现的思路和前面说过的一样。具体可以参考代码的实现。

                    MessageBox.Show("出现了错误：" + ex.ToString());
                }
            }
        }
    }
}

编写好程序后，现在我就是将编写好的addin放到arcgis里面去调试了，选择【Customize】

然后选择【Customize Mode】,弹出如下框。依次选择【Commands】、【Add From File..】

如下图所示，将开发的批量修改属性拖拽到arcgis的工具栏。

最后添加arcgis里面的图层。如下图所示，然后运行，最后结果如下图所示。
