Hi,

I'm trying to add a spread sheet to my map with xy coordinates.  I have 195 points I want to plot of polling sites in a county.  In the spread sheet I have the ID column (polling site), the X and Y columns.  When I go to add data it tells me I do not have an object ID.  I can get the points to map but can only see them if I "zoom to layer".  At that point I can't see any of the other layers that should be visible.

After reading a few threads it looks like I can either attach this to my precinct layer/shape file....or add it seperately.  However, I haven't been able to make either work.

Can anyone help me?  Please & thank you.

You need to make sure that when you add your XY data to choose the same coordinate system as your other layers.

Thank you.  So how do  I make sure the coordinate system is the same?

Right click one of your other layers and choose properties. There go to the Source tab and scroll down to Coordinate system.

Ok....they were all the same: GCS_North_American_1983.

What else should I check?

Is this the coordinate system you chose when adding your XY data?

If not use the WGS84 system, that usually works.

Geographic Coordinate Systems -> World and there choose WGS 1984

Yes, that's the one I chose (actually it populated automatically).

I don't see WGS84 anywhere.  Where should I be looking for that?
