地学综合信息图库管理系统的进一步开发应用

Further Development and Application of Geosciences Synthetic Information Maps Database Management System

为使原设计的图库管理系统达到管理和利用资源评价中海量图形和数据的目的,从实际需要出发进一步开发完善了本库管理系统。阐述了地学综合信息图库管理系统的空间数据来源,以及图库系统需要管理的图形及数据文件内容。在原有综合信息图库管理系统基础上,开发完善以下4方面功能:(1)系统中采用Access数据库存放元数据的路径,程序通过文件名查找元数据文件存放路径,读取元数据文本文件中的内容并显示;(2)利用MapGIS SDK二次开发库函数实现图形文件还原显示,以及利用VC++编程实现图库的目录及文件的在线删除功能;(3)利用MapGIS SDK库中的单类文件转换函数,开发了选定目录下多类(点、线、面)文件的批量转换功能,实现与其他GIS软件的资源共享;(4)使用Smart Install Maker实现图库管理系统的软件标准化安装,使该系统进入实用阶段,完成了'内蒙古东乌珠—额仁高比一带中大比例尺综合信息成矿预测'项目中的建库任务。

In order to manage and utile the maps and data in the older maps database management system,it＇s necessary to further develop this system.The authors introduced that where the spatial data sources about synthetic information mineral resources assessment come from,and what the contents of the maps and data files is.Based on the old design of synthetic information maps database management system,there are four new functions had further implemented.（1） Make use of access database to record the path of metadata file,and then search the path and read its connect according to the related file name;（2） Restore the display of the map using MapGIS SDK＇s function,and add a on-line delete function about the directories and files using VC ＋＋ programming;（3）Convert the MapGIS point,line and plane files to GIS Standards Format-SHP format in bulk according to single class translate function;（4） Implement software standardization installment of map storage management system taking advantage of Smart Install Maker.Now,this system had entered practical stage.It has been used to build the database perfectly for the project of metallogenic prediction of medium and large scale at region of the Dong Wuzhu-Erengaobi in Inner-Mongolia.
