Teach you how to get user location data

Recently, the U.S. Science and Technology blog affiliated Research Institute BI FDI published a report that analyzes how geographical data is collected and how geographic data will change the entire mobile industry.

Now that the number of smartphones with GPS is over 770 million, geographic data has begun to penetrate the entire mobile landscape. In addition to consumer applications like Foursquare and Shopkick, location-based services have many applications in the mobile arena. It can support advertising and many other services, such as weather, tourism applications.

The report specifically analyzes how mobile ads based on location-based data stimulate consumer interest, how location-based data functions improve application usage, and uncover the mysteries of basic technology and privacy issues.

The pure GPS solution and the latitude and longitude labels it generates are recognized standards for geographic data. But there are at least 4 ways to get geographic data:

1, cell phone signal Tower data: When the mobile device's GPS chip can not receive the GPS signal, the mobile device needs to communicate with the cell phone signal tower It is connected with and estimate the distance between it and the signal Tower to continuously report its geographical location. Geographic data obtained by this method is not as accurate as pure GPS data.

2. WiFi connection: This is a way to obtain accurate geographic data, but it requires a valid WiFi hotspot. WiFi addresses are one by one corresponding to GPS coordinates. It can accurately mark the location of the user, so many retailers are willing to offer free public WiFi services, so they can release the store mobile ads.

3. IP Address: Geographic location can also be obtained by the IP address related to the data connection. The accuracy of this method varies by operator and is less reliable than the above method.

4, User reports: When users register e-mail or mobile applications and services, they usually enter their geographical location and postal code. These data can be converted to GPS coordinates to establish a user base location file.
