Estimating the Area of Colombia

Your browser does not support Java, so nothing is displayed.

Estimate the area of Colombia from the map above. This map is "live." You can move the cursor to any point on the map by clicking at the desired point. You can fine tune the cursor's position by clicking on the arrows above, below, to the right, and to the left of the map. You can mark any box in the grid by moving the cursor within that box and clicking the Mark point button. Notice the applet keeps count of the number of boxes you have marked.
