This article shows you the positioning and application of Geolocation in HTML 5. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

HTML5 web technology is increasingly reflected in some mainstream popular websites. Many website technicians pay more and more attention to HTML5, especially in recent years, with the popularity of mobile Web App, Web-based applications become more popular and mature, at the same time, HTML5 is also hot. Although the standard of HTML5 is still in the process of being developed and formed, the special effects and charm shown by HTML5 have long conquered many outsiders.

In recent years, LBS has shown explosive growth with a variety of network applications. By the end of December 2011, the cumulative number of accounts in China's LBS market has reached 30.62 million. However, LBS still has some technical problems, such as the inability to accurately determine the geographical location of users. Now, with the penetration of HTML5 web technology in the technical development of electronic map, among its new functions, there is a Geolocation geographic positioning technology, which can provide a solution to the problem of inaccurate user location in LBS. This technology can locate the geographic location information of the user through some third-party wireless signals, such as IP, GPS, WI-FI and so on, and present the location on the electronic map.

Geolocation location technology does bring us a pleasant surprise, but for HTML5, the current pc and mobile browsers and developers do not fully support it. Geolocation location technology has only presented some LBS services on a small number of electronic maps. With the popularity of technology and the spread of new web standards, Geolocation location technology will certainly shine in the future. Through some current LBS applications, we can find that Geolocation can bring more freshness and vitality to location services.

1. The value of life: accurate climate broadcast anytime, anywhere

Last year, Pew Research Center, a US data research firm, surveyed a certain number of users of LBS location-based services, 46 per cent of whom were used to using the weather warning function. This shows that weather-related location services account for a very large share of LBS. In general, when we want to query the weather through the Internet, we always need to constantly enter keywords through the search engine to query the local weather. Although many navigation websites have introduced the function of opening the page to display the weather, sometimes the corresponding geographical location of ip is not your real location, so we have to search for weather information manually. The uncertainty of ip positioning makes weather LBS should adopt better positioning technology, or when you are away from home, convenient weather LBS may be more useful to you.

Let's take a look at what convenience Geolocation technology brings to weather services.

For example, if you are away from home today and do not know what the weather is like, you can use a browser that supports HTML5 mobile terminals to query the weather in a place where you can receive public Wi-Fi signals. Geolocation can accurately analyze the specific location of the area by receiving Wi-Fi signals, and finally quickly feedback the weather conditions of the area by connecting to the weather forecast. In addition, Geolocation can also use GPS and Wi-fi hybrid positioning to make a more accurate location of your location, so as to obtain more accurate weather information.
