虚拟旅游的意义有哪些呢？
1.首先当然是可以足不出户地通过互莲网技术游览全世界，如今Google EARTH和Google MAP的出现使这个需求成为现实。而GOOGLE 当然会继续趁热打铁，持续投入，继续自己的开发工作。下面的这个消息似乎来的比较

Volkswagen and Google are working together to develop a revolutionary new navigation system.
Together with the graphics card manufacturer nVidia, a revolutionary new navigation system is being developed in Volkswagen's Electronics Research Laboratory (ERL) in Palo Alto, California. This new system uses data from Google Earth to generate 3-dimensional images of the route. Moreover, the navigation system can gather online data to provide the driver with important real-time information, for example about the traffic situation or weather.
Volkswagen, Google and nVidia have been working on developing this new navigation system since October 2005. In January 2006 at the Consumer Electronics Show (CES) in Las Vegas, the partnership was able to present its first prototype, which comes closer to "virtual reality travel information" than any other system seen to date.
The central element is a touch-screen interface linked to Google Earth. Precise 3-dimensional maps, real-time traffic and route guidance updates and a search function set new standards in navigation technology. This so-called "open system" integrates the internet to meet the individual requirements of the driver and his passengers.
The prototype enjoys three important advantages over today's systems. Firstly: the 3-dimensional, photorealistic display of the surrounding area makes intuitive orientation easier for the driver and his passengers.
Secondly: important real-time data are fed into the system through a link to the internet. This means that, for example, traffic data and weather reports, but also any other information relevant to planning the journey such as filling stations, their opening times and current fuel prices are available, enhancing comfort, safety and reliability for the journey.
Thirdly: a further online link coupled to the search function allows the driver and his passengers to receive specific information about special features en route and at the destination – hotels, restaurants, cinemas and theatres are feasible examples. The driver and his passengers can even receive shopping data, right down to current prices, through the innovative navigation system. All such data is shown on the display.
At present, this innovative system is still in the development phase – no decision has yet been made about a possible series production launch.
Based in Palo Alto, California, the ERL is the Volkswagen Group's central research centre in the USA. In the heart of Silicon Valley, it is able to work directly with globally leading high-tech and start-up companies. The close working relationship between the ERL and these partners facilitates the design and development of innovative features and applications, which are then applied to test vehicles of the Volkswagen Group brands for further analysis.

2.缓解旅游景区人满为患的压力？
其实，很多人到了目的地才发现自己的出行决定是错的，这个地方也根本不是自己理想中的那样，如果在出行之前对景点进行详细的了解，这个委屈是可以避免的。
3.更多……，是否和可以缓解全球变暖呢，开玩笑吗，来看看国外论坛的观点。
Consider if you will for a moment the fact that cars, buses and airplanes put out CO2 into the atmosphere. If we are to prevent the (pollution) CO2 from entering the air, that means we cannot drive at our vehicles or fly our aircraft. If we are to cut down on the human emissions of CO2 people will have to do less traveling.
