Plugin-based GIS application framework: Research and implementation

Traditional GIS software faces some hot potato, for example, industrilization, specialization and high cost. In order to popularize GIS software, and reduce its cost, construct a plugin-based GIS application framework, which not only provides a nice reusable and flexible develop environment, but also supports special application fields faced developers when they put in practice some application project. After dissecting the essential and implementation mechanism of platform and plugin model, we present the object model, message mechanism and hierarchy of a plugin-based GIS application framework model, and apply this theory into the development and practice of large-scale GIS platform (MAPGIS7.0), which significantly promotes the extension platform function and GIS application.
