The invention belongs to the field of computer application and in particular discloses a network-based satellite cloud picture positioning method. The method is characterized by building a corresponding mathematical model and an algorithm according to the geographic information data in the preset area, obtaining the real-time user mouse position, matching the real-time user mouse position with the satellite cloud picture coordinate, displaying the corresponding geographic information and the real-time meteorological information and finally providing detailed and objective satellite cloud picture data information to a user. The PHP (hypertext preprocessor), JavaScript and the like are used to realize collaboration of a server and a client, a special wide band network is adopted as the transmission medium and the collaboration of different programs is realized by calling relevant standard functions, thus finally ensuring the method to be efficiently and stably carried out.
