My geo coordinate system for the map is&nbsp;ETRS 1989 UTM Zone 26N since my AOI is north of Portugal. One layer (see Screenshot) has the correct coordinate system and fits, the other a diff. CS and transformation. No idea how to get that layer to fit properly, can anyone help here?</P><P>Much apprechiated!</P><P>Ferret</P> Sun, 26 Mar 2023 10:43:06 GMT https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271716#M67187 furry_ferret 2023-03-26T10:43:06Z https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271719#M67188 <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2023-03-26 125632.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/66282i9534761EC5455293/image-size/medium?v=v2&amp;px=400" role="button" title="Screenshot 2023-03-26 125632.png" alt="Screenshot 2023-03-26 125632.png" /></span></P><P> </P> Sun, 26 Mar 2023 10:57:59 GMT https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271719#M67188 furry_ferret 2023-03-26T10:57:59Z https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271734#M67191 <P>Did the layer have a coordinate system or did you use</P><P><A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/define-projection.htm" target="_blank">Define Projection (Data Management)—ArcGIS Pro | Documentation</A></P><P>If it was the later, it was defined wrong and you have to determine what it is without defining it to what you want it to be</P> Sun, 26 Mar 2023 13:58:59 GMT https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271734#M67191 DanPatterson 2023-03-26T13:58:59Z https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271887#M67214 <P>If the .tif file has a predefined coordinate system, then the first time you bring it into that map, you have to use that coordinate system. Then you can set the layers coordinate system to the coordinate system you want it to be and export the .tif file out to that coordinate system using the data frame coordinate system.&nbsp;</P> Mon, 27 Mar 2023 13:41:31 GMT https://community.esri.com/t5/arcgis-pro-questions/please-help-with-projection-and-transformation/m-p/1271887#M67214 SLouq 2023-03-27T13:41:31Z
