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。
We research how to construct a spatial data model on oracle spatial ( database ) , and then construct our object - oriented spatial data model . we provide a webgis system which introduce the technology of j2ee , distribute componet , muti - layer and oracle spatial data storage ; the user can use it with vector spatial data 本文从理论上研究和探讨了基于oraclespatial (简称spatial ) ,怎样建立空间数据模型,在所建立的空间数据模型基础上,构建适合于webgis应用环境,为用户提供矢量空间数据操纵并满足用户需求的分布式组件化webgis系统。
