I used to look forward to the Chinese version of Google Maps in "Application Development and Analysis of Google Maps ".The birth of APIS is expected to create Google map applications for thousands of third-party websites. Today, I accidentally discovered that the Chinese map API has already appeared.
In fact, unfortunately, today I found that a Google Maps satellite map application developed by myself cannot display

Scale and resolution of Remote Sensing Images
The image resolution rate is an important indicator for determining the image accuracy. The image accuracy must meet the image recognition capability and accuracy requirements of the corresponding scale map update, and the map update cost must also be taken into account. Redundant resolutions increase the cost of purchasing weixing im

Recently in the commissioning of the GPS Beidou dual mode, has been debugging now, the following is a few words involved.GPS:GPS is the abbreviation for the English Global Positioning System (GPS). GPS started in 1958 with a U.S. military project, which was put into use in 1964. In the 1970s, the United States Armed Forces jointly developed a new generation of satellite positioning system GPS. The main objective is to provide real-time, 24x7 and globa

Global Positioning System (GPS) is the second generation of satellite navigation system in the United States. It is developed on the basis of the satellite navigation system of the Mer
LBS has been widely used in mobile devices and browsers. Based on APIs, it can easily implement address location-related applications, however, I still don't know how to obtain the user's location information behind these Apis. Today I spent some time studying it:
There are two ways to obtain location information: GPS and Wi-Fi.
1.GPS
The basic principle of GPS is to measure the distance between the satellite at a known position and the receiver of th
Satellite positioning System-gps/glonass/Beidou:About GPS, GLONASS, Beidou, Galileo system of popular Science please Google itself.GPS is the most widely used global positioning network and is standard for almost all smartphones. In a few years, Russia's GLONASS positioning function also gradually joined the smart phone chip, and GPs to form a dual positioning system, positioning speed greatly improved. China's self-developed Beidou navigation system,
