ArcGIS Pro 3.4| |帮助归档 摘要 Polygon对象是由 x,y 坐标对的连接序列定义的闭合形状。 说明 在许多地理处理工作流中,您可能需要使用坐标和几何信息运行特定操作,但不一定想经历创建新(临时)要素类、使用光标填充要素类、使用要素类,然后删除临时要素类的过程。可以使用几何对象替代输入和输出,从而使地理处理变得更...
// use the ConvexHull method from the GeometryEngine to construct the polygon geometry var newPolygon = GeometryEngine.Instance.ConvexHull(polylineBuilder.ToGeometry()) as Polygon; // queue the polygon creation createOperation.Create(polygonLayer, newPolygon); // execute the edit (polygon create) o...
Polygon autocomplete construction tools automatically sketch boundary segments that are shared with other polygon features. The shared boundary is inferred between the first and last vertex where they touch or cross other polygon features and form a trac
The image below shows four polygons created from points located within a maximum distance of 250 kilometers from one another. The two points (outliers) located beyond the aggregation distance are not included in any polygon. A stand-alone one-to-many relationship table is created to link the ...

This article describes how to create a polygon feature template with a predefined geometry using a preset template to enable creating features with the same geometry repetitively in different locations without using the copy and paste functions. 过程 In ArcGIS Pro, add the feature class to the map...
