TOPOG: A Computerized Worldwide Terrain Elevation Data Base Generation and Retrieval System
Kenneth P. Spies; S. Jean Paulson
Abstract: TOPOG is a computerized worldwide terrain elevation data base generation and retrieval system. It consists of software to generate TOPOG tapes from Defense Mapping Agency (DMA) standard terrain elevation data tapes, to create auxiliary random–access disk files containing TOPOG data for a user defined area, and to extract path profiles from the auxiliary disk files. The data base and software are designed for a CDC 6000 series computer with a NOS or NOS/BE operating system.
Keywords: computer software; data base; terrain elevation data; TOPOG
