Abstract:

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.
