What's the best way to go about uploading it. I believe ArcGIS doesn't accept .ecw, so how can I resolve this. Any help greatly appreciated.&nbsp;</P> Fri, 09 Aug 2024 13:36:38 GMT https://community.esri.com/t5/arcgis-online-questions/uploading-ecw-imagery-into-arcgis-online/m-p/1517455#M60753 ndrogemuller1 2024-08-09T13:36:38Z https://community.esri.com/t5/arcgis-online-questions/uploading-ecw-imagery-into-arcgis-online/m-p/1588097#M63742 <P>have you tried this?&nbsp;<A href="https://support.esri.com/en-us/knowledge-base/faq-can-ecw-files-be-directly-added-to-arcgis-online-000034280" target="_blank">https://support.esri.com/en-us/knowledge-base/faq-can-ecw-files-be-directly-added-to-arcgis-online-000034280</A></P><P>&nbsp;</P> Fri, 21 Feb 2025 17:39:05 GMT https://community.esri.com/t5/arcgis-online-questions/uploading-ecw-imagery-into-arcgis-online/m-p/1588097#M63742 Laura 2025-02-21T17:39:05Z
