**QUICK REFERENCE**

The best way to learn to use the GLOBE tools for looking at data is to
use the tutorials available from the main GLOBE Maps and Graphs page.
From the GLOBE homepage (http://www.globe.gov/) select \"Maps and
Graphs\" from the navigation bar at the left, and then follow the links
to the tutorials.

**CREATING A MAP**

1.  Start at the GLOBE Homepage http://www.globe.gov/ and select \"Enter
    the GLOBE Site\"

2.  Select \"Maps and Graphs\" from the navigation bar at the left.

3.  Select \"GLOBE Maps\".

You will now see a map of the whole Earth, displaying GLOBE student
maximum air temperature data for the current day.

**To Change Map Center Location and Map Magnification (Zoom)**

-   ![](media/image2.png){width="0.4027777777777778in" height="2.1in"}Be
    sure the \"Click on map to:\" control (shown below) has the small
    circle next to \"\[+\]zoom\" filled in with a dark spot. If this
    circle is not filled in, click in the small circle one time.

schools whose name contains Lycee. If you specify the school name Lycee
and the country Benin, you will only get GLOBE schools whose name
contains Lycee that are located in Benin.
