侧扫声呐探测数据管理系统设计与实现

     

摘要

侧扫声呐调查获得的数据是一类格式特殊、类型多样、结构复杂、数据量庞大、包含信息丰富的数据,设计和建屯侧扫声呐数据管理系统是数据深层次应用和共享的前提.针对侧扫声呐数据的特点,本文将侧扫声呐获得的完整数据体系规划为原始数据层、标准化数据层、目标数据层和元数据层4个层次,设计并开发了侧扫声呐数据管理系统,整个管理系统包括原始数据管理模块、数据预处理模块、数据处理模块、质量评价模块、数据库管理模块和数据成果集成展示与服务模块.各个模块既町独立运行,相互之间又有关联,形成一个相对完整的管理系统,实现了对侧扫声呐原始数据及备类成果数据多样化有效处理与管理.该系统已经应用于我国近海海洋综合调查与评价专项中的全部侧扫声呐调查数据的管理,并取得了较好的效果.%Side-scan sonar data is characterized by special format, large amount and rich information. It is necessary to design and implement the side-scan sonar data management system for these data's sharing and reusing. Aiming at the characters of side-scan sonar data, the data system is divided into four layers: raw data, standard data, aim data, and metadata. A massive side-scan sonar data management system is designed to manage the data system. There are six modules in this management system. That is, raw data management, data preprocessing, data processing, data assessment, database and data display & service. They can not only operate individually, but also be associated. So a unitary management system comes into being to realize the effective management of both raw data and product data. It has been applied to manage all the side-scan sonar data of Comprehensive Inshore Investigation and Assessment, and good effect has been acquired.
