Secondly , apart from the spatial character , the operational data of sea area use management are characterized by multi - source , multiple scale , and coordinate , complex type and large quantity , etc , so this paper has laid emphasis on studying the spatial data model and the data framework related to the management of sea area use , solved a series of key technical problems such as check and correction , organization and structrue , quality management and standard norms for the geographical sapce data associated with the management of sea area use , proposed various practical and effective ways of storing and managing spatial and non - spatial data and established the spatial data base system for the management of sea area use 其次,由于海域使用管理业务数据除空间特性外,还具有多源、多尺度、多坐标、类型复杂、数据量大等特征,因此,本文重点研究了与海域使用管理相关的空间数据模型与数据框架,解决了海域使用管理相关地理空间数据的复合与订正、组织与结构、质量管理与标准规范等一系列关键技术问题,并提出了切实有效的空间数据和非空间数据的不同的存储、管理方式,建立了海域使用管理空间数据库系统。
The main research work are summarized : geographic spatial data storage and sharing in gml format , svg format encoding and visualization ; geographic spatial data organization and conformity with object - oriented relation database ; the data parsing and format transforming among gml , svg and shape file ; a general framework establishing and a prototype development of web gis server software system in a multi - tiered distribute structure utilizing soap / web service 主要研究内容包括:地理空间数据的gml编码存储与共享和svg格式编码与地理信息的可视化表达;地理空间数据的组织以及它与关系对象数据库的整合; gml 、 svg和shape格式的解析与转换;用soap / webservice技术构建分布式多层体系的webgis服务器端软件系统的总体架构和原型系统的开发实现。
With the development of gis and knowledge and rules joined , gis is destined to develop from a computer system that only gathers , disposes and analyzes geographical data to an intelligent system that provides experts " knowledge and services for spatial decision and support . after analyzing deeply current application data models of streetlight management gis , this thesis points out their disadvantage and necessity and importantness of using knowledge and rules in application data model of streetlight management gis 知识与规则是人类活动中所总结和归纳出高层次的内涵,随着gis的发展,在知识与规则逐渐融入的情况下,形成基于知识与规则的gis应用数据模型,使gis由原来的单纯采集的、处理和分析地理空间数据的单一应用系统,逐渐发展为向提供专家知识、为空间决策支持服务的智能化服务系统。
