摘要
计算机技术的发展促进了图形图像技术的发展,由此出现了各式各样的图形图像数据格式,但不同格式之间存在数据共享的问题,计算机图元文件(CGM)是国际标准化组织制定的标准,具有科学性和可共享的优点.MAPG IS是集图形图像、计算机技术、地理信息系统于一体的软件,在国内G IS领域占据重要地位,在石油、房产、测绘、管网等领域发挥着重大作用,但是目前CGM数据在MAPG IS中还不能有效地读取,影响了一些数据的使用.通过对CGM数据格式的研究分析,找到了CGM与MAPG IS之间沟通的桥梁,实现了与MAPG IS软件的集成,并通过实例进行了验证,证明能够使CGM数据更好地应用于G IS领域.
The development of computer technology promotes the development of graphic technology, and there appear many kinds of graphic data formats. But the problem of data sharing arises due to the different formats. CGM （computer graphic metafile） is a standard of ISO, and it has the advantage of being scientific and sharable. MAPGIS is a type of software, which combines graphic technology, computer technology and GIS technology. And it occupies an import position in GIS field, such as oil, house property, mapping, pipe network and so on. But CGM data can not be read effectively in MAPGI, thus affecting the data use. This paper investigates and analyzes the CGM data format, finds a bridge between CGM and MAPGIS, and realizes the integration of the two. Furthermore, it is proved by a sampie test that CGM data could have better application in GIS area.
