https://community.esri.com/t5/geoprocessing-questions/spatial-join-of-two-polygon-layers-where-presence/m-p/1271908#M26780 <P>Hello, I'm relatively new to GIS and am hoping for some guidance!</P><P>I know what I'd like to accomplish in plain language but am not sure how to make it happen in GIS. I have two polygon layers, layer one and layer two. Wherever they overlap, I'd like to modify a column in layer one and change entries from N to Y. I also would like to make sure that all other columns in layer one are un-touched. Is spatial join the right feature for this? Both layers are made from multiple individual polygons.&nbsp;</P><P>That is the simplest way I can phrase it, please let me know if clarification or further info is needed.&nbsp;</P> Mon, 27 Mar 2023 14:05:45 GMT MadisonGiuntoli 2023-03-27T14:05:45Z https://community.esri.com/t5/geoprocessing-questions/spatial-join-of-two-polygon-layers-where-presence/m-p/1271908#M26780 <P>Hello, I'm relatively new to GIS and am hoping for some guidance!</P><P>I know what I'd like to accomplish in plain language but am not sure how to make it happen in GIS.

You will have to create a spatial join every time you open a new project.&nbsp;</P><P>You can try using attribute rules to overlap and update the column fields from N to Y. I found a community article (slightly related to your issue) that might be helpful.&nbsp;</P><P><A href="https://community.esri.com/t5/attribute-rules-videos/using-attribute-rules-with-joined-tables-to-pass/td-p/1008944" target="_blank">https://community.esri.com/t5/attribute-rules-videos/using-attribute-rules-with-joined-tables-to-pass/td-p/1008944</A></P> Wed, 17 May 2023 06:29:42 GMT https://community.esri.com/t5/geoprocessing-questions/spatial-join-of-two-polygon-layers-where-presence/m-p/1289972#M26873 VaibhavS 2023-05-17T06:29:42Z
