I need to add a X,Y coordinate grid as a layer to be put on top of my geological map. I couldn't find an easy way to do this in the forums, so I hope someone here can help me. I do NOT have a lot of experience with ArcGIS, so I would need a step-by-step tutorial on how to do this. The map I have already has coordinate data (sample points and so on that I've added to the map are based on GPS coordinates) but I am not sure how to visualize the coordinates as a grid.
Any help is greatly appreciated.
Edit: Forgot to add version, I'm running ArcGIS 10
Not sure if it is what you need, but since I cannot get why would you need to draw coordinate lines (furthermore, you said "not necessarily between the individual points"), I guess you might need just usual grids one can generate in ArcMap.
