Google Maps
Google Maps is a free, online map service provided by Google. It offers a draggable map, route planner and business locator for the U.S. and Canada, the UK and Ireland. It is currently in beta testing.
Development
Google Maps was first announced on the Google Blog on February 8, 2005. It originally only supported users of Internet Explorer and Mozilla web browsers, but support for Opera and Safari was added on February 25, 2005.
Like other Google web applications, a large amount of JavaScript was used to create Google Maps. As the user drags the map, the grid squares are downloaded from the server and displayed to the user. When a user searches for a business, the location is pin-pointed with a red pin, which is actually a transparent PNG placed over the map. A complete explanation of the technical side of Google maps can be found here [1].
Features
Google Maps features a draggable map that can be zoomed in to show detailed street information. The user can control the map with the mouse or the arrow keys to move to the desired location. To allow for quick movement, the "+" and "-" keys can be used to control the zoom level. Users may enter an address, intersection or general area to quickly find it on the map.
Search results can be restricted to a certain area, thanks to Google Local. For example, someone can enter a query such as "Waffles in Toronto" to find restaurants serving waffles near the city. This can be used to find a wide variety of businesses, such as theatres, restaurants or hotels.
Like many other map services, Google Maps allows for the creation of driving directions. It gives the user a step by step list of how to get to their destination, along with an estimate of the time required to reach it and the distance between the two locations.
The "link to this page" link on each Google Maps map puts a long URL on the clipboard which contains the latitude and longitude. The latitude and longitude can be used as input to TerraServer-USA, which in some cases has higher resolution imagery.
Interesting Satellite Images
In early April 2005, an alternate view to see satellite imagery of the area displayed, was activated. Notably, and unlike other satellite services which provided images in the past, it is possible to overlay directions which are correctly positioned on the satellite image [2].
Full zoom dimension is only available for relatively populated (urban) regions.
