Network-based satellite cloud picture positioning method

Abstract

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.

Description

(1) Technical field [0001] The invention belongs to the field of computer applications, in particular to a network-based satellite cloud image positioning method. (2) Background technology [0002] With the development of the economy and the advancement of science and technology, the society's demand for weather forecast is getting higher and higher, and the corresponding weather detection methods are also changing with each passing day. The information application based on network technology is also developing continuously. It is far from meeting the needs of meteorological stations at all levels for disastrous weather monitoring and analysis. Satellite cloud images urgently need to provide more detailed and objective information and products for real-time weather forecasting. The development of satellite cloud image product application technologies and methods based on network technology has become an improvement. It is an urgent problem that needs to be solved due to the ...

Problems solved by technology

The problem is: (1) In large-scale weather forecast production software such as MICAPS, the satellite cloud image display is only a small part of its huge functions, and the application is relatively cumbersome, which cannot be well integrated with the monitoring and early warning based on the B / S structure in actual business. (2) In the satellite cloud image applications based on the B / S structure developed by various units, they are generally displayed in simple pictures, without providing fine and dynamic positioning functions for satellite cloud images, and lacking corresponding associated real-time weather Information cannot meet the needs of multi-level users such as provinces, cities, and counties
