ALGORITHM FOR GENERATING DMA USING INTERPOLATION

摘要

PURPOSE: An algorithm for generating the DEM(Digital Elevation Modeling) using an interpolation is provided to make the grid DEM finally by extracting an elevation point having an elevation value from a national digital map and applying the interpolation method to it. CONSTITUTION: A layer including the information of the elevation value is extracted from the digital map of a DXF(Drawing Interchange Format) file format and converts it into an internal file format. The TIN(Triangular Irregular Network) is generated by using the extracted elevation point. The grid DEM is generated by using the extracted elevation point through the interpolation method.
