AN EXPERIMENT ON THE INTEGRATION OF MAP, REMOTE SENSING AND GISTAKING THE DYNAMIC MAPPING OF THE DELTA AREA OF CHANG JIANG (YANGTZE RIVER)AS AN EXAMPLE

地图学、遥感、地理信息系统是三门独立的科学技术，但它们又存在着紧密的关系。本文以１９９１年太湖流域及南京地区洪涝灾害评估和１９９２年长江三角洲地区城镇扩展与开发区调查的动态制图为例，阐述地图－遥感－地理信息系统融合组成的技术系统，并讨论三者一体化的接口问题。

Map, Remote Sensing and GIS are three independent sciences. But there is a close relationship among them. Not only from the view of the development of diciplines, but also from the view of application, people recognize that they must be combined and become an integrated one.The works of the dynamic mapping of the delta area of Chang Jiang (Yangtze River) include the flood damage assessment of the central Tai Hu Lake watershed in 1991 and the investigation on the urbanization and Eco and Tech Development zone of the area in 1992. All the works require expedient and accurate mapping products. The paper begins with the technique flowing charts of two examples, illustrates its key technology, and makes their contents and relationship clear. The deeply understanding of the technology system of the combination of map. RS and GIS can meet the users′ requirements.If you want to design a good integrated system of Map. RS and GIS. you must deal better with their port, use general microcomputer or littlecomputer and their outside supply as hardward base,design a set of relative softwares, implement the input and output of the maps. construct the map base of remote sensing image and the geographic coordinate of GIS. and make the information flow fluent in the integration of them.
