1. Once the site has opened, take a moment to look it over. Be sure to look at the tool bars and familiarize yourself with the different tools (at least what they look like)
2. Once you have looked at the different tools, lets use some to get you more familiar with their uses:
a. Select the icon that looks like a magnifying glass with a + sign in it. This is the zoom tool, used for magnifying . To magnify a portion of the viewing window, click and drag the tool around the area that you wish to magnify. Try this on one of the areas of the photo set that looks interesting to you.
b. Now select the icon that looks like a hand. This is the pan tool, used for dragging. The pan tool allows you to drag the photo set so that you can see things in the viewing area that are not there currently. Try dragging the photo set to the left and right.
c. Next you should select the icon that looks like a globe. This is the full extent tool which will allow you to zoom out to see the entire photo set again (a “global” view).
d. Last you need to use the measuring tool. This tool looks look a little ruler. To use it, select the icon and move the cross hairs over one of the objects that you want to select. Single click on that object. Now, move the cross hairs over the other object and single click. A window will appear that tells you the distance between the objects you selected. Also, a line that goes between the two points you have chosen will appear (to ensure you are measuring what you think you are). Now, on your own, measure the distance between any two objects that you find interesting on the photos.
3. You may notice near right side of the viewing window a tool bar that says “layers”. This will allow you to choose different sets of photographs to view. In this case, each layer will be a specific time period that the photographs were taken during. Take a moment to select different layers to view. Do this by adding or removing a check next to the layer that you want to select or deselect.
