Abstract

Developing a method for interpolation of data points for forming DTM involves thousands of complicated computations. Checking of such computations requires errorless and well-defined input data and end results from a large number of DTM points. Measured, or actual, DTM data points may not be available or invariably have errors which affect the course of the computations and analysis. Most of these problems can be overcome by mathematically generating DTM data points.  This paper focuses on developing software, called MathDTM, for generating mathematical (simulated) DTM data at desired specifications. An overview of the development and capabilities of MathDTM software platform based on Windows system is presented. The developed software was used for testing the performance and accuracy of different interpolation methods of Surfer software. The results of these tests were then discussed and evaluated.
