附加信息

This is expected behavior. True curves or circular arcs are stored in a blob field inside the enterprise geodatabase (any RDBMS type). Densified or simple features are stored in the shape column instead to represent the true curve. As a result, querying the area or length of the shape column returns a different measurement than querying the true arc or curve itself (there is a slight difference). This is the same for other data like 3D length (querying the shape column only gives the 2D calculations).

解决办法

A user maintained attribute column can be created. Either the Add Geometry Attributes or Calculate Geometry Attribute tools can be used to populate the field. Refer to https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/add-geometry-attributes.htm or https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/calculate-geometry-attributes.htm for more information.
Arcade can also be used to obtain the values and then automatically populate a user-maintained field that stores the area and length via an attribute rule.
