Study on Automatically Plotting Contours Method Based on MapInfo and Surfer

摘要

Contour is a powerful tool of analyzing spatial characteristics of geographical factors. The traditional hand-drawing style had been eliminated and much professional mapping software had its own flaws and shortcomings as well. So, how to integrate the functions and advantages of various mapping software together so as to improve the efficiency of contour mapping is an issue which is worth of studying. This paper introduced a new method of plotting contours that adopts VB as developingplatform and utilizes OLE technology to carry out integrated development with Maplnfo and Surfer. This method had been applied widely during the protection and administration of ecological environment of mining area. The contours plotted in this way are relatively precise and it has greatly improved the efficiency of plotting actions.
