My map has various data sources. Sometimes I get the following error:
"This coordinate system has a geographic coordinate system that differs from one or more data sources in the map.
Use the Transformations button to set or change these transformations"
For example, when I view the properties for the Data Frame, I get the error. I understand that I can use the Transformation tool as shown in the attached image, but I'm not sure which settings to select. I don't understand how to use the tool in general.
Any guidance or advice you can offer is greatly appreciated.
