topic Difference in area calculation geometryService vs ST_AREA in ArcGIS JavaScript Maps SDK Questions https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/difference-in-area-calculation-geometryservice-vs/m-p/233265#M21763 <HTML><HEAD></HEAD><BODY><P>Hi all, I keep getting&nbsp;small differences in calculating the area of a feature. Using the geometryservice (with a geometry from FeatureService) from the esri API (3.17), the result of an area calculation differs slightly&nbsp;from&nbsp;running ST_AREA(SHAPE) directly on my Oracle database. Parameters used (spatial reference, polygons etc.) are all the same. Any ideas what could be causing this?</P></BODY></HTML> Wed, 05 Jul 2017 08:58:49 GMT ArjanLuchies 2017-07-05T08:58:49Z Difference in area calculation geometryService vs ST_AREA https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/difference-in-area-calculation-geometryservice-vs/m-p/233265#M21763 <HTML><HEAD></HEAD><BODY><P>Hi all, I keep getting&nbsp;small differences in calculating the area of a feature.

Do both actually do a calculation with the same numeric representation?</P></BODY></HTML> Wed, 05 Jul 2017 10:12:24 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/difference-in-area-calculation-geometryservice-vs/m-p/233266#M21764 DanPatterson_Retired 2017-07-05T10:12:24Z
