This tool works in conjunction with the button accessed by expanding the "Show/Hide Map Tools" link. For help with this map tool please see Find lat/long.
Follow these steps to use the function.
1.) Use the button to get the lat/longs for two or more points.
2.) After selecting the lat/longs for multiple points click the button. A pop-up window will appear with all the lat/longs listed.
Note: If you cannot get the Accumulated Lat/Long pop-up window to appear you might want to check your system for pop-up blockers or hold the control key down on your keyboard while simultaneously clicking the button.
