An Investigation of the Accuracy of Multiquadric Equations of Topography.
Abstract
A new technique has been developed in representing topography by the summation of equations of quadric surfaces having unknown coefficients. This study tested the conic multiquadric equation of topography for eight geomorphologically diversified areas. Data points were selected for two modes of operation; significant points on a surface and a grid pattern. The criterion for evaluating the accuracy of the computed surfaces was the United States National Map Accuracy Standards. Four hyperboloid multiquadric equations were also tested to show their justification as one of the many possibilities for computing multiquadric surfaces. (Author)
