Example Embodiment

[0027] The GIS application system of the present invention is divided into three parts: a GIS platform, a plug-in and an application system interface.

[0028] 1. GIS platform

[0029] The GIS platform implements the core functions of the GIS application system, and at the same time has the functions of calling, managing and coordinating external plug-ins, as well as the function of transmitting standard messages and events to the external plug-ins.

[0030] 2. Plug-in, which performs a specific function.

[0031] 3. GIS system interface

[0032] The GIS system interface includes two standard interfaces, one is the platform interface implemented by the GIS platform, and the other is the plug-in interface implemented by the plug-in.

[0033] The platform interface is completely implemented by the platform, and the plug-in is just called and used. The platform interface realizes the one-way communication of the plug-in to the platform. The plug-in can obtain various resources and da...

Abstract

GIS application system includes GIS platform, plug in modules and system interface. The said system interface includes platform interface and interface for plug in modules. Plug in modules implements specific service logic related tasks. Realized by the platform, platform interface is called and utilized by plug in modules. Realized by modules, interface for plug in modules is called and utilized by GIS platform. Through technique of GIS platform, the invention builds multiple self-defined interfaces in program to make plug in modules able to access each resource in program. Meanwhile, GIS platform is able to carry out specific function through calling plug in modules. After interface of plug in module is opened to public, any company and personal can develop own plug in modules to solve inconvenient operations or add new functions so as to increase expandability of software and prolong life cycle of software system.

Description

technical field [0001] The invention relates to a GIS (Geographic Information Technology) application system and a development method thereof, in particular to a GIS application system and a development method thereof which execute specific functions by calling plug-ins. Background technique [0002] In recent years, geographic information technology (GIS) has developed rapidly and has been widely used in many fields such as traffic monitoring, urban planning, and traffic navigation. For these applications, many manufacturers have developed corresponding software systems, but these GIS application systems are generally developed for a specific application alone, and different application systems lack scalability at the binary level. [0003] The realization of a large-scale GIS system usually requires the collaboration of multiple people for software development and design. At this time, a difficult problem is how to seamlessly integrate the software codes written by several...
