【gis插件】arcgis插件界址点编号工具、C#实现思路(附插件下载链接)

数据：界址点图层、宗地图层

要求：找出宗地对应的所有界址点号，对这些界址点号以J1开始按顺序排列

        要找出宗地所对应的所有界址点号，这里只要执行一个标识 即可得到这样得到的结果。

难点在于对界址点的编号，经过检查，这些界址点存在明显的乱序，比如这样：132564 

 图形复杂，太复杂了，这种图形，用arcgis无论怎么排序、编号，它编号都得乱哇。 

不得已只能动用C#的神秘力量

第一步做一个标识的操作，让所有的界址点有了归属，标记了每一个界址点属于哪一个宗地。

接下来的任务就是对宗地的界址点进行编号，每个宗地的界址点都从J1 开始编号。

宗地内遍历每一个界址点，找到距离这个界址点最近的宗地点，然后给这个界址点赋予这个宗地点的这个序号。遍历完界址点之后，对这个界址点进行排序就会得到我们想要的结果了。

    public void aaaa222(IFeatureClass fc_jzd, IFeatureClass fc_zd,string fieldname){string txtfile = "";SaveFileDialog save = new SaveFileDialog();save.Filter = "文本|*.txt";if (save.ShowDialog() != DialogResult.OK) return;txtfile = save.FileName;int jaindex = fc_jzd.FindField(fieldname);if (jaindex < 0){MessageBox.Show("界址点图层不包含"+ fieldname+"字段，请先做标识操作。");return;}jaindex = fc_zd.FindField(fieldname);if (jaindex < 0){MessageBox.Show("宗地图层不包含" + fieldname + "字段，修改输入字段名称。");return;}List vsdata = GetUniqueValue(fc_jzd, fieldname);ISpatialFilter spatialFilter = new SpatialFilterClass();List dataitem_result = new List();dataitem_result.Add("序号,"+fieldname+",界址点编号,X,Y");//+ "\r\n";int index = 1;//spatialFilter.WhereClause = fieldname + " = ";foreach (string str in vsdata){spatialFilter = new SpatialFilterClass();spatialFilter.WhereClause = fieldname + " = '" + str + "'";IFeatureCursor fcur_zd = fc_zd.Search(spatialFilter, false);IFeatureCursor fcur_jzd = fc_jzd.Search(spatialFilter, false);List jzd_ps = new List();List presult = new List();IFeature feature_zd = null;IFeature feature_jzd = null;mPoint mp = null;List zd_points = new List();while ((feature_zd = fcur_zd.NextFeature()) != null){IGeometryCollection geoCol = feature_zd.Shape as IGeometryCollection;  while ((feature_jzd = fcur_jzd.NextFeature()) != null){mp = new mPoint();mp.X = (feature_jzd.Shape as IPoint).X;mp.Y = (feature_jzd.Shape as IPoint).Y;jzd_ps.Add(mp);}IPoint pp = null;IPointCollection h1 = geoCol.Geometry[0] as IPointCollection;                    for (int a = 0; a < h1.PointCount; a++){pp = h1.get_Point(a);mp = new mPoint();mp.X = pp.X;mp.Y = pp.Y;mp.index = a;zd_points.Add(mp);   }IPolygon4 p4 = feature_zd.Shape as IPolygon4;IGeometryBag interbag = p4.get_InteriorRingBag(geoCol.Geometry[0] as IRing);IGeometryCollection interCol = interbag as IGeometryCollection;int neihuan = 1;for (int c = 0; c < interCol.GeometryCount; c++){IPointCollection inth = interCol.get_Geometry(c) as IPointCollection;for (int a = 0; a < inth.PointCount; a++){pp = inth.get_Point(a);                           mp = new mPoint();mp.X = pp.X;mp.Y = pp.Y;mp.index = h1.PointCount+ neihuan;zd_points.Add(mp);neihuan++;}}List temppp = new List();foreach(mPoint ppitem in jzd_ps){mPoint pi = GetDirect2(ppitem, zd_points);//zd_points.Where(x => GetDirect(ppitem, x));//mPoint pi= zd_points.FirstOrDefault(x => GetDirect(ppitem, x) == true);if(pi!=null)temppp.Add(pi);                      }temppp = temppp.OrderBy(x=>x.index).ToList();int reallyjzd = 1;temppp.ForEach(x=> {if(x!=null)dataitem_result.Add((index++) + "," + str + ",J" +( reallyjzd++) + "," + x.X + "," + x.Y);//+ "\r\n";});}  }File.WriteAllLines(txtfile, dataitem_result);MessageBox.Show("执行完成！");}

这一个方法需要界址点、宗地图层有一个相同的字段，也就是先必须进行标识操作。

后来想了想，如果直接用代码执行按位置进行选择，也能得到和宗地对应的界址点。于是就能把标识这一个步骤省略掉了。 勾选上 “按位置进行编号” 即可。

   public void aaaa_position(IFeatureClass fc_jzd, IFeatureClass fc_zd, string fieldname){string txtfile = "";SaveFileDialog save = new SaveFileDialog();save.Filter = "文本|*.txt";if (save.ShowDialog() != DialogResult.OK) return;txtfile = save.FileName;int jaindex = fc_zd.FindField(fieldname);if (jaindex < 0){MessageBox.Show("宗地图层不包含" + fieldname + "字段，修改输入字段名称。");return;}List dataitem_result = new List();dataitem_result.Add("序号," + fieldname + ",界址点编号,X,Y");int index = 1;IFeature feature_zd = null;IFeatureCursor fcur = fc_zd.Search(null,false);while ((feature_zd = fcur.NextFeature())!=null){IGeometryCollection geoCol = feature_zd.Shape as IGeometryCollection;string strJAvalue = feature_zd.get_Value(jaindex).ToString();ISpatialFilter spatialFilter2 = new SpatialFilterClass{Geometry = feature_zd.Shape as IGeometry,   //SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects,   //相接};IPoint point1 = (feature_zd.Shape as IArea).LabelPoint;IFeatureCursor featureCursor2 = fc_jzd.Search(spatialFilter2, true);IFeature feature_jzd = null;//List jzd_ps = new List();//界址点点集存放List zd_ps = new List();//宗地点集存放mPoint mp = new mPoint();while ((feature_jzd = featureCursor2.NextFeature()) != null){mp = new mPoint();mp.X = (feature_jzd.Shape as IPoint).X;mp.Y = (feature_jzd.Shape as IPoint).Y;jzd_ps.Add(mp);}#region 获取宗地的点集IPoint pp = null;IPointCollection h1 = geoCol.Geometry[0] as IPointCollection;for (int a = 0; a < h1.PointCount; a++){pp = h1.get_Point(a);mp = new mPoint();mp.X = pp.X;mp.Y = pp.Y;mp.index = a;zd_ps.Add(mp);}IPolygon4 p4 = feature_zd.Shape as IPolygon4;IGeometryBag interbag = p4.get_InteriorRingBag(geoCol.Geometry[0] as IRing);IGeometryCollection interCol = interbag as IGeometryCollection;int neihuan = 1;for (int c = 0; c < interCol.GeometryCount; c++){IPointCollection inth = interCol.get_Geometry(c) as IPointCollection;for (int a = 0; a < inth.PointCount; a++){pp = inth.get_Point(a);mp = new mPoint();mp.X = pp.X;mp.Y = pp.Y;mp.index = h1.PointCount + neihuan;zd_ps.Add(mp);neihuan++;}}#endregionList temppp = new List();foreach (mPoint ppitem in jzd_ps)//遍历每一个界址点{mPoint pi = GetDirect2(ppitem, zd_ps);//zd_points.Where(x => GetDirect(ppitem, x));//mPoint pi= zd_points.FirstOrDefault(x => GetDirect(ppitem, x) == true);if (pi != null)temppp.Add(pi);}temppp = temppp.OrderBy(x => x.index).ToList();//从新排序int reallyjzd = 1;temppp.ForEach(x =>{if (x != null)dataitem_result.Add((index++) + "," + strJAvalue + ",J" + (reallyjzd++) + "," + x.X + "," + x.Y);//+ "\r\n";});}File.WriteAllLines(txtfile, dataitem_result);//输出TXT文件MessageBox.Show("执行完成！");}

结果

为了程序执行的效率以及稳定性，不生成图层、不存储字段信息，插件把处理的结果按

"序号,宗地代码,界址点编号,X,Y"

把所有信息输出到TXT。

直接把TXT文件拖到arcgis里边，展点，就是我们想要的结果了。
