Features

Coordinate Convert is the process of transforming from one coordinate system to another coordinate system, which is achieved by establishing a one-to-one correspondence between the two coordinate systems. The coordinate conversion service realizes the function of mutual conversion between 4D AutoNavi coordinates, Baidu coordinates, Sogou coordinates and other coordinates.

Note: This service does not support the conversion of offset GPS coordinates (such as Baidu coordinates, Gaode coordinates, etc.) to unoffset GPS coordinates. Coordinate conversion service does not currently support international services, and address resolution is limited to China.

Applicable Situation

• Realize the conversion from the existing coordinate system to the required coordinate system as required.
  For example: In order to use the Gaode map, the user needs to convert other coordinates to Gaode coordinates.
