Virtual Earth Mobile Application System
Virtual Earth Mobile is an innovative application in the field of computers. When the Microsoft Networks Virtual Earth website was launched a few months ago, the first thing many people did was they tried it on the Windows Mobile device. This website was very advanced. It pushed the envelope of what you are allowed to do with a pure browser based application using DHTML, AJAX as well as JavaScript. The Windows Media Application can access for the maps of the program Virtual Earth.
The working of the website is rather simple. There is no SDK, but through the Virtualearth.com, you are able to gain the important information regarding how to make use of the Virtual Earth’s JavaScript control for displaying a map. The Virtual Earth servers can perform better rather than map tiles. They are also able to carry out a number of flavors of searches. The most simple of all the searches is the searching for a particular address.
For example, you can even consider particular address string (e.g. “418 Hampster Avenue, Toronto, North York”) and then do the HTTP POST request to Virtual Earth server. You will also receive a JavaScript string like “SetViewport (latitude 1, longitude 1, latitude 2, and longitude 2). These four co-ordinates imply a rectangle on the planet Earth where the address is being located. Nevertheless, for a Street address like, which is fundamentally a point, a rectangle would not give any sense. However, if you are searching for a particular location, you will definitely require a rectangle. Therefore, the JavaScript function of the program Virtual Earth has a SetViewport Control, which only need you to assess the JavaScript string, which can cause the map control for displaying the rectangle as specified by the 4 co-ordinates.
Another type of search you can do making use of this software application is searching for a business. Supposing you are searching for the restaurants in Toronto, you require doing the similar type of HTTP POST request to the Virtual Earth server. The only exception would be that now you will pass in restaurants as well as the four latitude, longitude co-ordinates will cover the area you wish to search. You will receive a string that includes almost 10 search results. Every search result will include the name of the business, its address, phone number as well as latitude or longitude. You will also obtain a Boolean, which indicates if there are any more search results. If so, then you are able to make another request for seeing the next group of ten search results.
The new Virtual Earth Windows Mobile 5.0 has made it easier for adding two novel features. The first being the “Find a Contact” that can show you the address out of your contact list as well as maps. The second feature is the GPS (Global Positioning System). This feature reads out your current position from the GPS device as well as maps it down for you. You will find more about the Virtual Earth Mobile application, its source code, and even its help file on the website.
