摘要
虽然GIS软件在努力地追赶IT主流技术的发展,取得了许多有意义的进展,但相当一部分现代软件技术至今没有在GIS软件实现中得到有效的使用。GIS发展至今,虽然已经存在各种类型的GIS平台和应用软件,但要像搭积木一样组装成满足自己需求的GIS应用软件及实现各种GIS系统之间的集成仍然很困难。采用组件式软件方法开发组件式软件GIS是一种解决思路。详述了GIS开发的历史、组件技术、组件式GIS开发的基本原则及组件式GIS的缺点。
Though GIS has been endeavoring to adopt new information technology and thus made great achievements, technology-gaps donot hesitate to hinderperfection. There is stillsome difficulties in building GIS applications with the existing GIS platforms like playing with toy bricks. Components geographic information systems present a new solution. History of GIS development and component tech- nology, and also ComGIS 's principles and demerits are detailed.
