USING AHTD's ROAD CONDITIONS MAP |
The routes on the map are intelligent features. These features within the map will react to your passing the cursor over them by changing from your normal pointer (usually an arrow pointing up and to the left) to a hand with a pointing finger. They may also change color when the cursor is positioned over them. This tells you that the graphic element has some intelligence built in to it. Hovering over the feature will "activate" it, and provide further information about the route (ie. route number, route description, and related conditions).
The viewer module has several capabilities that are not evident in the normal browser user interface.
If you click the right mouse button anywhere inside the map itself, you will be presented with a "pop-up" menu of commands. The standard commands are as follows and are activated by clicking the command with the LEFT mouse button:
Click this command to see all of the graphics that have been downloaded in this particular session.
Click this command , then drag a box over the area you wish to zoom in to. To drag a box, click and hold down the left mouse button at the top left corner of your desired area, move to the bottom left corner, and release the mouse button.
Click this command to zoom in around the center of the map - a 2X zoom factor
Click this command to zoom out around the center of the map - a 2X zoom factor
Click this command to create a magnifier window. Then as you move your cursor over the map, a magnified view at your cursor position will be displayed in the magnifier. In Netscape Navigator, click on the "Close" button to remove the magnifier. In Internet Explorer, a single click the right button anywhere will remove it.
