附加信息

When creating geometry objects via ArcPy, the spatial reference object must be set to enable high precision coordinates. For the code samples provided, adding `spatial_reference = WGS84` accomplishes this and allows the geometries to be interacted with as expected. Geometries created without a spatial reference are stored in a low precision mode which collapses geometries within short distances of one another. Note that properties like the area are rendered in the non-existent unit of 'square decimal degrees', and for real calculations a projection should be applied before calculation at this time.

解决办法

Create polylines from arcpy.Polygon with an array of points.
Create a polyline feature class using Create Feature Class (Data Management) tool.
Create a polygon feature class from polylines with the same Create Feature Class (Data Management) tool.
