Research Of Transmorming Each Other Between Map And Database

The map of the mining area is the important part in constructing mining GIS. Not only it include 2D and 3D information, but also include all kinds of attribute information of object. Management data in map by database system is important to realize the communication from mining map to mining digital information system or 3D physical exploring information system. It will also deeply influence the researching of mining GIS.According to the feature of mining GIS ,the feature and organizing approach and constructing style of mining data were analyzed deeply in this paper .The constructing of data model and the designing of database were completed through OPP of database .How to organize and save and maintain the object attribute data in AutoCAD were given in this paper. The bridge between map and database were constructed in this paper. The data in map were updated while the data in database were updating ,on the other hand , the data in database were updated while the data in map were updating.According to the theory and approach of software project, the collective designing and detailed designing of the transformation between map data and database data were given in this paper .The probable problem in original map were researched and the approach of how to resolve was given .How to add and delete object attribute have been resolved .The approach of transforming between map and classifying information in map .At the same time ,data were checked by the approach of direct checking and indirect checking while the data were inputted or outputted.In a word, it is a deeply theory and practical researching to the transformation between map data and database data form designing of database to checking of data. It will make a large advance in development and revolution of constructing mining GIS.
