Need help aligning data in different coordinate systems
Using ArcPro 3.4 (this is a limitation imposed by a custom toolbox I have to use for validating data)
The data I'm dealing with is boundary data used in NextGen 911 situations.
Boundary layer A is a boundary layer controlled by the state, and editing it is not an option. It is maintained in WGS84.
Boundary layer B is a layer from a client that must align, vertex by vertex, with boundary Layer A. Boundary layer B is maintained in UTM15N.
My job is to make layer B align with layer A. The differences between the two boundary layers are slight but noticable.
If I load the state's layer A into my map, it will be displayed in my map's coordinate system, which is currently the same as layer B, UTM15N. Is this okay, or would it be better to change my map coordinate system to WGS84 first? Does it matter what the map coordinate system is set to?
OR...should I bring/project the client's layer B into WGS84 and do the alignment that way, knowing I'd have to bring that layer back to UTM when it's all said and done?
In case it's not obvious, I am looking for a process where I only have to do this one time. I'm worried that projecting the data back and forth will introduce some "projection drift", if you know what I mean. If I submit layer B to the state and it's not 100% aligned with layer A, it will get rejected, and I am going to have to submit data quarterly.
