Theweathernetwork.com uses Microsoft Virtual Earth’s interactive maps to display cloud cover (satellite) and precipitation (RADAR) information. The interactive maps give you, the user, a number of choices when viewing imagery. You can customize the map to your liking by: turning cloud cover and precipitation layers on and off; search for and centre any part of the world; zoom-in and zoom-out; loop images from the past; and adjust layer speed and layer transparency.
This function allows you to start your interactive experience by searching for the city you would like weather information for. Simply type the name of the city you are looking for. Make sure the spelling is correct. A city not in our data base will give you a "no matches found" message. If you are not sure of the spelling, type in the first three letters of the city or town to pick from a list.
The Weather Network gives you access to three types of sky cover information. You can control turning each layer on or off by simply clicking the check boxes provided.
Once you have chosen a location and the layers you want to see, you can view the most recent snapshots of the weather over your location. The animation controls let you play snapshots for at least 2 hours, taken every 10 minutes. This gives you a good idea of where the cloud, rain, or snow has fallen and generally where it’s headed. The controls are: Oldest Frame; Rewind; Pause; Play; Stop; Fast-Forward; and Newest Frame.
The time displayed below the map shows you when the weather snapshot was taken. It will display your local time and also display the timezone acronym (example: NST, EST, AST, CST, MST, PST, NDT, EDT etc.).
To make sure you can properly see the names of cities and towns on the map, use the transparency slider. This control allows you to adjust the transparency of the layers on top of the map.
You can also use the speed slider to control how fast the animation plays on top of the maps. If you play the maps at a slower speed, it will be easier to see precipitation approaching your location and read the time display below the map.
The Zoom In tool lets you see a specific area on the map in more detail, such as cities, towns, and roads. Currently, we do not provide cloud cover and precipitation data at all zoom levels.
The Zoom Out tool will allow you to get an overall picture of weather across one or many provinces, but with less geographic detail.
The compass wheel is a tool that lets you pan/move the map. Click on this tool in the direction you want to move. By holding down the left-click on your mouse over the compass wheel, you can move the map in a continuous motion.
You can view cloud cover and precipitation imagery on three types of maps. "Road" view gives you a graphic based map with all roads and highways labeled. "Aerial" view will show you a terrain shot of a region, but no road or place names will be labeled. "Labels" will let you see both road labels and terrain on the same map. Try all three to see which one you like.
All layers on the map update every 10 minutes. If you have been viewing the same images for more than 10 minutes, the interactive maps will let you know that it is time to “Refresh Map”. To do this, simply hit the Refresh Map button on the right hand side below the map.
