| 摘 要： | 光栅数据经过分层失量化形成点、线、面文件,在建立地图库之前要进行误差校正,以满足精度要求。地图库管理系统采用层类的概念,以图幅为单位来管理地图数据。图幅对接时,接边处数量少、误差不大时,采用自动接边;反之,则采用交互式接边或半自动接边功能。

| Abstract: | Through stratified vectorialization,raster datas can form spot,line and plane documents Before establishing map database,errors should be corrected.By using stratified idea and chart as unit,mapbase is managed.When charts are juncting,if the amount of juncting part is small and has little mistake,automatic juncting method can be used;otherwise,inter-juncting or semi-automatic juncting method can be used. |

| Keywords: | Geographical information system mapbase chart juncting |
