摘要
结合目前GIS数据在不同软件之间交换以实现共享的需求,选择国内用户较多的GIS软件(MapGIS、MapInfo Professional)为研究对象,在剖析MapGIS坐标系统定义理论的基础上,通过分析MapGIS不同坐标系统数据转为MapInfoMIF交换格式的特点,发现了由于坐标系统定义不一致而导致的转换坐标存在的若干问题,并提出了MapGIS不同坐标系统数据的正确转换方案,为MapGIS数据向MapInfo转换提供了方法保障,也为其他GIS软件之间的数据交换提供了思路。
Combine with the requirement of data share that could be done in exchanging mass data in different software, the author select MapGIS and MapInfo software as research subjects, which have nots of users at home. Based on studying the coordinate system definition of MapGIS, by analyzing the character when MapGIS data are translated into MIF exchanged format of MapInfo, the author found that the exchanged result has some matters in different coordinate system definitions, so we offer a correct way and a practicable project for exchanging data of different coordinate systems. It is not only offer a way to exchange data from MapGIS software to MapInfo, but also offer an idea for data exchanging in other GIS softwares.
