Abstract: The drawing and printing program of earth resistivity was designed and implemented, on the basis of observational data of Tongzhou seismic station in 2008.The discussion focused on the object-oriented programming, double buffering drawing technology and WYSIWYG(what you see is what you get) printing realization.The program was integrated with SODE database seamlessly.It was easy to operate and well interactive, with a lot drawing styles.Consequently, it was successfully applied in several seismic stations.
