Abstract：Making of the wide-area electronic sand table deals with several techniques,such as aviation remote sensing,geographic information system and computer 3D image simulation display and so on.The making method of the electronic sand table and its application for large seismic exploration area were mainly discussed in this paper.The remote image correction which determines the space location accuracy of the electronic sand table and the DEM data acquiring method were also introduced in this paper.At the same time the exact application and important effects of the technique in seismic exploration were analyzed and summarized in this paper.
