The Lab O'Evil

Drop by the data drive and grab a copy of the data for this lab. Then make a copy of that folder, just so you have a nice, clean, copy to go back to once you mess things up.

I've provided 6 GIS layers. 5 of them have messed up coordinate systems and/or datums. The one that is correct is the Ellensburg North topo sheet.

Your goal is to get all 6 to properly overlay with no spatial errors. You'll need to use both the define projection and reproject command.

A few hints:

• remember, the firstlayer you open into an arcmap window defines the coordinate system and datum from which the others try to reference. So, you will want to open each layer individually into its own window to see what you've got. Or at least your starting point.
• You will be doing a lot of opening windows and turning things on and off....
• And trying and trying and trying, and failing. And deleting what you did and grabbing a clean copy and trying again.

You will hand in This Document - all filled in. Typed, not handwritten.

3 points. Due next tuesday.
