Abstract

A general minicomputer program package for height interpolation is presented. It is written in FORTRAN and interpolates a digital height model (DHM) from arbitrarily distributed reference points and breaklines, using the Finite Element Method. From the DHM digital profiles can be derived for orthophoto production and digital contour lines can be interpolated and plotted. The paper describes the principles of interpolation and the structure of the programs. Finally the efficiency of the package is demonstrated by the results of processed practical examples. -ITC Bibliography
