At Pro 2.6.0 the calculated geometry of a feature class attribute is incorrect. A rectangle 66’ x 660’ is 1 acre (43,560 sq. ft.), although, the calculation by right-clicking the attribute and calculating...
Area Unit: Acres
Coordinate System: Current Map
produces an incorrect calculation. The same procedure was worked in a 2.5 version and the calculation is correct.
(The map measure tool calculates accurately in both versions.)
Attribute calculation same feature class in v. 2.6 and 2.5
GDB Feature class
Spatial ref: NAD 1983 HARN StatePlane Florida West FIPS 0902 (US FEET)
v. 2.6 of polygon feature 66’x660’ = 10.7639 ac. (468,875 sq. ft.) incorrect
v. 2.5 same polygon = 1.0 ac. (43,559.93 sq. ft.) correct
See image capture. The two attributes far right are in v.2.5
Image: screen capture attribute table shows area calculations using Pro 2.6 and 2.5. The two attributes far right are in v.2.5
Let me know if you need additional information.
I get the same problem calculating Acres in NAD_1983_2011_StatePlane_California_IV_FIPS_0404_Ft_US and NAD_1983_California_Teale_Albers_FtUS but not NAD_1983_UTM_Zone_11N. The test polygon is 19.198 Acres calculates as 206.564 acres.
Re case number requested by Dan Patterson,
Esri Case #02608276 - ArcGIS Pro 2.6 \\ Calculate Geometry Values Incorrect; Different from Pro 2.5
"...that this defect has been approved through our review process, and is now in the hands of the Product Team."
Good afternoon y'all,
We've got the following defect for this issue in our systems right now:
BUG-000132660 - Incorrect values of the area calculated from the 'Calculate Geometry Attributes' tool in ArcGIS Pro.
This is being fixed for Pro 2.6.1. If you're currently utilizing Pro 2.6, you can work around this behavior by using the 'Field Calculator' in lieu of the 'CGA' GP tool with the following expression: !shape.area@acres!
That expression will provide the correct area measurement and will avoid the necessity to backtrack to Pro 2.5.
