I used GDA2020 coordinate system.</P><P>I calculated some statistics inside grids. It seems like grid cell areas are slightly different. Can somebody explain this to me?</P><P>Thanks</P> Tue, 09 Apr 2024 06:51:09 GMT https://community.esri.com/t5/arcgis-pro-questions/fishnet-grid-cell-sizes-not-uniform/m-p/1407412#M81602 cskari 2024-04-09T06:51:09Z https://community.esri.com/t5/arcgis-pro-questions/fishnet-grid-cell-sizes-not-uniform/m-p/1407429#M81607 <P>If you used geographic coordinates to specify the cell dimensions then projected it or used a projected area to get its planar dimensions, then the cell sizes will be different because of the fact that that the EW extent of a cell decreases as you head poleward becoming a point at the poles</P><P><A href="https://en.wikipedia.org/wiki/Geographic_coordinate_system" target="_blank">Geographic coordinate system - Wikipedia</A></P><P>&nbsp;</P> Tue, 09 Apr 2024 08:33:13 GMT https://community.esri.com/t5/arcgis-pro-questions/fishnet-grid-cell-sizes-not-uniform/m-p/1407429#M81607 DanPatterson 2024-04-09T08:33:13Z
