附加信息

ArcGIS Pro 2.7 has resolved some issues with Acres unit conversion. This issue compares Geodesic area calculated by Calculate Geometry Attributes tool with Planar area calculated by Measure Features interactive tool, which is inappropriate and the values will almost always be different (the planar area does not represent real area on the Earth or geoid rather a Cartesian approximation based on a projected coordinate system). The Calculate Geometry Attributes tool in ArcGIS Pro 2.7 supports Planar area computation for the supplied data, and produces a value that matches exactly the Measure Features interactive tool. The Geodesic area calculation is different from the Geodesic option of the Measure Features interactive tool, as the Calculate Geometry Attributes tool uses a Shape-preserving geodesic method to more accurately represent the shape while calculating the area by including additional vertices, as described conceptually in the links below: https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/project.htm https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/calculate-geometry-attributes.htm https://pro.arcgis.com/en/pro-app/latest/arcpy/classes/geometry.htm

解决办法

Run the Calculate Field tool with the following expression '!shape.area@acres!' to get correct results that match the Measure tool. The following documentation describes the Calculate Field tool examples for calculating geometry unit conversions: https://pro.arcgis.com/en/pro-app/tool-reference/data-management/calculate-field-examples.htm.
