In HTML5, a new geolocation property has been added to the Window.navigator object, which can be accessed using the Geolocation API. The Geolocation property of the Window.navigator object has the following three methods.void GetCurrentPosition (onsuccess,onerror,options);This method is used to obtain the user's current geo-location information.Navigator.geolocation.getCurrentPosition (function (position) {

How to use the HTML5 geo-location feature The positioning function (geolocation) is a new feature of HTML5, so it is only available on modern browsers that support HTML5, especially handheld devices such as the iphone, which is more accurate in geolocation. First we want to check whether the user device browser supports geo-positioning, and if so, get geographic

WINDOWS8 new Geo-location geo-positioning function. WINDOWS8 based on IP address positioning, accuracy of about 25-kilometer, system positioning services do not provide orientation, height, speed, address and other data. When you need to use the positioning feature, you need to display the prompt user, and you can turn the positioning service on or off in Control

In the previous section we obtained longitude and latitude values by positioning, but it is difficult for the average person to understand these figures.Geo-Information anti-coding: is based on these latitude and longitude to return the location of the relevant text description information , these text description information is encapsulated in the Clplacemark class , we call this class "Landmark" class.Geo-Information anti-coding is implemented using

First of all, the failure of this attempt belongs to the kind of death on the way to the hospital. Based on the augmented reality of geo-positioning, AR holographic Reality, is a tall on the argument that the straightforward point is a cottage similar to casually go such applications. Open the app, search for surrounding information, and then overlay the information on what the camera has captured. Idea: Use mobile phone to control the Camrea in un
