Troubleshooting

Error message: Your browser has JavaScript turned off.
The map viewer page uses JavaScript to send map requests to the map server.
To change your settings open your browser Preferences or Options and enable JavaScript. In Internet Explorer you'll find this in the security settings. You do not have to restart your browser or your computer after you enable JavaScript. Simply click the Reload button.

Why does it take so long?
If you are using a modem it can seen to take a while for each new map to load. Each time you make a selection you request is sent back to the map server. Be patient, if you keep clicking you'll just send more requests back to the server and it will take even longer.
