The Design and Analysis of a High-Production Mini-Computer System for Regridding Digital Terrain Elevation Matrices.

Abstract

This report studies a new algorithm for the regridding and transformation of Digital Terrain Elevation Matrices. The new algorithm uses sequential accesses to mass storage devices rather than the random methods used by the software system currently installed at the Defense Mapping Agency. Due to the simplicity of the new algorithm, minicomputers can be used in place of a larger mainframe computer. Four potential minicomputer systems are examined. Benchmark test results are given which show the feasibility of minicomputer use. Recommendations are made concerning the minicomputer to select if the new algorithm is to be implemented. (Author)
