Research And Realization Of Geographic Information System Based On VB And MapX

The present paper states the topic is in the research module type GIS technology foundation, uses tour information system which the MapX module technology development develops, has carried on the analysis and the discussion to the country tour information.(1) through to discovered based on the GIS technical support tour information system comparison and the analysis that, Has the graph data and the attribute data integration based on the GIS technical support tour information system, not only may use the graph direct-viewing to display the data, but also may use the attribute data to indicate merit and so on it more exhaustive characteristic, but the traditional information transmission method manages these data unavoidably to feel lacks the ability to do what one would like. Therefore, proposed unifies the GIS technology and the tour information, the design has developed the tour information system;(2) through carries on the comparative analysis to the geographic information system using the development 3 kind of forms, proposed suits the tour information system by the module type development way the development, and take the VB and MapX combination form, chooses the Liaoning Province Anshan city as the experiment site, develops the Liaoning Province Anshan city tour information system, realizes small practical geographic information system software, the paper detailed introduction system construction of data, the data organization and each main function, has achieved the tour information inquiry, the management, the demonstration and the output integration;(3) the shortest path and the male exchange has carried on the theory discussion to the tour information system in while the question, proposed based on the Dijkstra algorithm public transportation network shortest path question solution, will solve the stand achievement which the shortest path will obtain to search the stand, and will pass through these stands line constitutions these stands to trade while the matrix, the union trades while the number of times request, produced traded while has realized the algorithm, determined feasible trading while the plan.
