I'm currently working on an internship at my university creating home range maps with squirrel data that's been collected in one of my classes. I've been having some issues with some of the data; when I import the data from Excel into ArcMap and project the points to WGS 1984, sometimes it will show up either in Europe or South America instead of on my campus. I've had multiple GIS teachers here try and help me out with this issue and nobody has been able to tell me why this is happening. I've even used the "define projection" tool to try and get the layers on the same projection and even that hasn't helped.
If anyone has any ideas on why this is happening, I could really use some advice.
Thanks in advanced!
