Design and implementation of roadway geological sketch picture drawing system based on MapGIS

This paper analyzes the components of roadway geological sketch pictures (RGSP) and designs the drawing flow of RGSP based on MapGIS and the component modules of the drawing system, according to the management business requirements of the metal mining and survey data. The object-oriented thought is used in this thesis to analyze the component spatial entities of RGSP and the topological relations of these spatial entities, and then the spatial data model and logic model of RGSP drawing system are established. RGSP drawing system is realized based on MapGIS platform and component based development technology, which provides application basis and practical experience for the information construction of mine geological map (MGM).
