The ArcPy module is used to script these ArcGIS analyses, providing a productive way to perform geo-analyses and automate map production. Likewise, a multipart feature can be created from an array of arrays of points as shown below using the same cursor. Since the point geometry already includes these properties in itself and you already defined the new point geometry correctly with all of these properties, you shouldn't have to set them explicity one by one. If you always go clockwise around the polygon, and always subtract the. da و Cursor ها کارکردن با Geometry ها از جمله Point، Polygon، Polyline. Spatial Reference.
