Investigation of the Application of 'Array Algebra' to Terrain Modeling.

Abstract

This report investigates the application of array algebra to ETL's terrain modeling procedure in the following manner: analyze array algebra to verify specifically the equivalence of array algebra and the conventional least-squares solutions; analytically and empirically compare the computational efficiency of ETL's terrain modeling algorithm using the current least-squares method and the array algebra technique and investigate the applicability of Rauhala's array algebra to the ETL terrain modeling algorithm. The results showed that the array algebra algorithm is computationally equivalent to the least squares algorithm but has higher implementational overhead. The array algebra algorithm is also less efficient for the ETL terrain modeling problem.
