I run the intersect tool (analysis) in ArcMap and the geometryEngine.geodesicArea on the WAB for the same pair of polygons.
It seems to be a significant difference in the calculated area. I already converted both outputs to Acres.
Are there any known issues on the calculation of areas, or which way is provides the accurate results?
Thanks.
Update: The difference is due to the fact that ArcMap uses the planarArea to calculate areas. For small sized area it won't make a difference. However, the calculation of areas with long length, Arcmap results are not accurate.
