随着遥感、地理信息系统与全球定位系统等各项技术的成熟,对遥感、地理信息系统与全球定位系统的集成的要求变得越来越迫切,有关这种集成系统的理论、技术和方法逐渐成为地理信息学的重点,有关这种集成系统的开发、研制和应用逐渐成为诸多与之相关的学科发展中的重中之重。不同专业背景的研究者从各自的需要、背景出发纷纷发表不同的见解,作者从地理信息流本身的特点出发,分析了遥感、地理信息系统与全球定位系统各自的特点,阐述了集成的可能性和必要性。

With the development of remote sensing,GIS and GPS,their integration become a hot point of geoinformatics. Because the integration of RS,GPS and GIS has involved in many academic areas and researchers,their conceptions and ideas about the integration are introduced with different academic background On the basis of the characteristics of geoinformation stream,the authors have analyzed the features of GIS,RS and GPS respectively and discussed the possibility and necessarity of their integration After two years'developing a real integration system the authors introduce the conception,model and problems to which more attentions should be paid.
