The Origin of Building GIS Software Development Model

AbstractThe current situation and causes of software crisis are first introduced in this paper, and then software engineering and software reuse technology used for solving software crisis are presented. GIS software development is continuously developing with software reuse technology, but it has its own industrial characteristics. The current software architecture and GIS software development techniques cannot meet the requirements of application development. Thus, a new generation of service-oriented GIS software architecture and GIS software development model are proposed. Superiorities of building-type GIS software development model are also briefly analyzed
