Introduction to the GPS software of G1 and how to enable the GPS module We still use G1 as an example. G1 is equipped with a hardware GPS chip. However, most of the available GPS maps in G1 currently do not support offline image libraries, that is to say, you must ensure that you have a cmnet or Wi-Fi connection

The odd solution to the intersection of two polygon in the GPS fence and the odd solution to the gps fencePreface The area of the origin area measured by the GPS measuring instrument is then submitted to the system. The system needs to check whether the origin area overlaps with other regions. If the overlap exceeds 10%, it is necessary to warn that the origin ar

GPS is converted into a hundred degrees longitude and latitude, and gps is converted into Baidu longitude and latitude Recently, Baidu's api is used for map positioning. Baidu's background sometimes stops to obtain the longitude and latitude, and the results are written by Apple. CLLocationManager is used to obtain the longitude and latitude in the backend. However, the latitude and longitude errors obtai
