- The system stores spatial data and characteristic data into central database , and provides services to users in server / client mode . as the research emphases of this thesis , several key sub - systems are designed and realized . the digital map input and maintenance subsystem performs format conversion , editing and updating of spatial data ; the rail - track video playing subsystem uses video recording as reference data , then plays , inquires and traces the corresponding frames in synchronous to the scaled mileage , realizing the query of the active picture frames ; the digital map query subsystem fulfills the map query , preview and spelling of digital map orthograph
其中，地形图输入与维护实现了数字地图的格式转换、编辑处理以及空间数据的更新操作，解决了不同格式空间数据的互相转换问题；线路录象播放将线路录像数据作为系统的一种索引数据，活动影像的画面与里程相对应，实现了基于线路录像的播放、查询和检索的功能，实现了基于活动画面的查询检索功能；数字地图子系统完成了图形查询、数字地图与线路正射图像浏览、图幅拼接等功能。 - Thus using gis technique to manage the debris flow hazard ' s spatial data would be a suitable method . based on the wholly design of the debris flow hazard database , this thesis begins with setting up the debris flow hazard graph database with mapgis tool . following the work flows , i . e . vectorization , graphic edit , error adjustment and map collection
探讨了在mapgis中如何快捷有效地建立泥石流灾害图形数据库，即按照矢量化、图形编辑、误差校正、图幅拼接等流程进行；选用microsoftaccess建立泥石流灾害属性数据库；通过在图形数据库和属性数据库中设立主关键字来实现图形数据和属性数据的无缝连接。 - First , the thesis designs a whole geo - spatial data bank . generally , it involves in fundamental information preparation , writing standards , graph layer division , graph digitizing , collection of attribute data , edition , topological treatment , pretreatment , graph splicing , incorporation of attribute data and the final establishment
论文首先对研究区地学空间数据库进行了整体设计，大体经过基础资料准备、制定数字化图层及属性文件格式标准、划分图层、数字化图形与采集属性数据、编辑修改与拓扑处理、进行预处理、图幅拼接与属性数据合并，到地学空间数据库建立。
