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.
There is a Note in there that not all geographic transformations are installed and if one isn't offered, you can download it
And if you want to get everything into a common coordinate system, then use the Project tool and provide the transformation there
Thank you very much Dan! I will look through the information at the links you provided. I do want to get everything into a common coordinate system and the Project tool sounds like the way to do it.
I am not familiar with the Project tool. I tried searching ArcMap but I didn't find anything. Where do I find the Project tool?
Also, I'm not 100% sure which coordinate system to use but I think I should use NAD83(CSRS98) ?? Is that correct, the map is for the area along the border of Minnesota and Ontario, Canada
I don't use arcmap any more, but if memory serves
Arctoolbox, Data Management tools, Projections and Transformations, Project
The NAD83 thing with CSRS98 rings a bell, but as long as they are in the same one
Sorry for the delay in responding. I will need a few days to study the information at the links provided. I'm still trying to figure out which projection (or whatever) to use. I will reply back with either more questions or to mark as answered. Thanks again.
