摘要
测量控制成果管理系统是基础地理信息系统的重要组成部分 ,许多单位通常采用一般的关系数据库技术来组建 ,但因缺乏地形图作背景 ,致使查询结果很不直观。为达到图、文、表并茂的效果 ,以方便外业测量查找控制点位 ,本文提出了利用组件式GIS与MIS无缝集成技术管理测量控制成果的原理与过程 ,并着重阐述了所涉及的空间数据格网索引、符号化、数据变焦显示、查询等方面技术方法。实际应用表明 ,该技术方法不仅能实现对测量控制成果良好的管理功效 ,而且与采用独立的GIS平台相比 ,具有开发快捷。
Surveying Controlling Results Management System(SCRMS)is an important part of fundamental GIS.It is often constructed by general RDBMS, which,however leads to the inquired results not intuitional because of the lack of cartography. For overcoming that, the principles and procedures to manage the surveying controlling results based on seamless integration of MIS with ComGIS are presented, in which some methods such as spatial data grid-index,symbolization, data multi focuses display,inquiry and so on are described. The applications in engineering practice testify that these methods can realize the SCRMS efficiently and economically.
