Abstract
A description of HIFI, a general minicomputer program package, is presented along with a review of the experience gained with height interpolation by finite elements. The examples refer to the accuracy of DEM (Digital Elevation Model) interpolation and to the operational use of HIFI. Main applications are the derivation of digital profiles for orthophoto production with the Zeiss Orthocomp Z 2 analytical orthoprojector and the derivation of digital contours for automatic plotting. The required computing times are reasonable and the resulting computing costs are low.
