You can also choose to delete the polygon feature once it has been converted to a point. If the Delete Polygon check box is checked, the polygon feature is deleted once the point is created. If the check box is not checked, the polygon feature is not deleted. ...

你要素存在几何问题，先用复制要素，然后在把复制后的要素进行几何修复就能解决问题了
Polygons can be created from points to determine the distribution pattern of point features. For example, creating soil maps based on irregular point samplings of soil types, simulating the cellular c

可以把面数据转换成点数据，转换时选择质心。点数据的属性信息自带xy坐标，可以通过属性添加到属性表中。默认属性表不显示坐标信息
下面是arcgis help里的讲解: Adding the x,y coordinates of the centroid of a polygon layer to a new field 1. Optionally, start an edit session in ArcMap. Calculating a field is faster outside of an edit session, but you won't be able to undo the calculation. ...
Output = pPoint. X To add the x coordinate of polygon centroids: Dim Output As Double Dim pArea As IArea Output = pArea. Centroid. X 4.Type the variable Output into the second text box. Do not enclose it in quotes or brackets. 5.Click OK The units of the calculated values will be...
1.建表 2.添加GIST索引 3.插入数据 3.1 点(POINT) 或使用多点(MULTIPOINT) QGIS中显示几何如下: 3.2 线(LINESTRING) 或使用多线(MULTILINESTRING) QGIS中显示几何如下: 3.3 多边形(POLYGON) 或使用多边形集合(MULTIPOLYGON) QGIS中显示几何如下: 3.4 几何集合 arcmap 创建方形缓冲区 思路:先构建圆形缓冲区,在...
