附加信息
Geometry in a shapefile is stored differently than a file geodatabase. The perfect circle is stored as a curve and mathematical circle definition in the database, whereas in shapefile it is densified coordinates that resemble a circle. The geometry difference between a mathematical curve definition and a densified polygon stored in shapefile is responsible for the area difference in Calculate Geometry Attributes. Learn more about shapefile limitations here: https://pro.arcgis.com/en/pro-app/tool-reference/appendices/geoprocessing-considerations-for-shapefile-output.htm#GUID-B845DF9F-78C9-439F-9674-2BFEEFF8D58E Refer to the following section: Parametrically defined curves (also known as circular arc curves) are not supported on shapefiles. Parametric curves are created by editing geodatabase feature classes, as described in Create circular arcs. Circular arc curves use a mathematical formula to draw the curve. If you export a geodatabase feature class containing circular arc curve features to a shapefile, the curved features are transformed to simple line features with closely spaced vertices to capture the curved shape.重现步骤
