The instructions for this chapter and the accompanying screenshots were developed using a Macintosh computer. You will notice slight differences if you are working on a computer that uses a Windows operating system. Screen shots that show how to install and launch the GIS software are provided for both operating systems.

You may want to adjust the size of this window to make it tall and thin, then drag it to one side of your screen. This will allow you to keep the instructions visible on one side of your screen while you work with the data on the other side.
