User Requirements and a High Level Design of the Hydrographic Software/Data Processing Subsystem of an Airborne Laser Hydrography System

摘要

The requirements for the Hydrographic Software/Data Processing Subsystem of an Airborne Laser Hydrography System were documented. A timing analysis of the automated processing determined that a 10 million-instruction-per-second computer would be needed to satisfy the requirements and meet the other constraints. A timing analysis of the required interactive data processing determined that 50-60 man hours of interactive processing would be needed for each hour of data collection. A high-level software design was produced from which the expected number of lines of code was estimated to be 20,000. A conceptual hardware configuration and a development plan were produced. Using the results of the timing and hardware analyses, changes in the requirements and constraints were recommended which make the HS/DP Subsystem feasible while preserving its technical performance.
