As an example, the above execution body may make an application for acquiring the information of target distance from the typhoon to the target position to the maritime map software through network; the maritime map software transmits the information of target distance to the above execution body through network after receiving the application. The information of target distance may include but is not limited to at least one of the follows: a target distance value and a target direction.
Step 203: obtaining typhoon time difference information based on the above information of target distance and the typhoon wind speed information.
