多媒体技术在地理信息系统中的应用 of multimedia technology in geographic information system target=_blank）

多媒体技术在地理信息系统中的应用 target=_blank（Application of multimedia technology in geographic information system target=_blank） Application of multimedia technology in geographic information system Guo Jiyuan Zeng Wen (School of information engineering, China University of Geosciences, Wuhan 430074) The key problem in the application of multimedia technology in geographic information system is: how to effectively manage multimedia data and spatial data; secondly, in the process of, how to realize the function of multimedia. It is pointed out that with the extended relational data model as a multimedia data model is more appropriate; multimedia function depends on the multimedia data format - RIFF, and the application of multimedia data. And finally shows the application of multimedia technology in geographic information system. Key words multimedia technology, geographic information system, spatial data, attribute data, regional analysis, data model CLC number TP391.4 The first author Guo Jiyuan, female, lecturer, born in 1956, 1982 graduated from Huazhong University of Hankou branch, with a bachelors degree, is mainly engaged in computer graphics and multimedia technology in the teaching and research work. Nowadays due to the rapid rise of multimedia technology and the rapid development of the application software, more and more extensive use of multimedia technology. If the application of multimedia technology in geographic information system (geographic information system, referred to as GIS) software, will greatly enhance the GIS information expression ability, enlarge the application fields of GIS. So how will the multimedia technology the application in the GIS software. We think that two aspects should be: one is how to design multimedia data to be dissolved in the GIS database, and to ensure two-way analysis of retrieval and GIS software can provide a variety of power; the second is in the application process, how to realize the multimedia playback functions. The follow
