  3. First, the author makes the waihuan road in tianjin as the study object. through analyzing of system target and user ' s demands, the author designs the spatial database and attribute database on the base of webgis software selected. the author connects the two kinds of data by the road section number and constructs the professional module not only to realize the management of waihuan road but also to evaluate and predict the pavement performance

    為提高公路管理工作的效率,本文將人工神經網路技術應用於路面性能預測中,進行了基於webgis的路面管理系統的結構和功能設計,研究內容分為以下兩個方面:首先,以天津市外環線為研究對象,通過對系統的目標、用戶的業務需求分析,進行空間數據庫和屬性數據庫的設計,選擇適當的webgis軟體,在此基礎之上通過路段編碼進行空間數據和屬性數據的動態鏈接,建立路面管理系統專業模塊,在實現對外環線路面信息管理的同時,利用這些信息對路面性能做出評價和預測。
  4. On the base of the relative theories above, we design a spatial data mining prototype system based on j2ee, which includes three functional modules : spatial data management and interactive module based on web - gis, sdm ( spatial data mining ) module, and database service module

    在相關理論研究的基礎上,設計了一個基於j2ee的空間數據挖掘原型系統。系統是以通用空間數據庫為核心,包含三個功能模塊:空間數據管理和人機交互模塊;空間數據挖掘模塊( spatialdatamining , sdm ) ;數據庫服務模塊。
  5. 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,由於海域使用管理業務數據除空間特性外,還具有多源、多尺度、多坐標、類型復雜、數據量大等特徵,因此,本文重點研究了與海域使用管理相關的空間數據模型與數據框架,解決了海域使用管理相關地理空間數據的復合與訂正、組織與結構、質量管理與標準規范等一系列關鍵技術問題,並提出了切實有效的空間數據和非空間數據的不同的存儲、管理方式,建立了海域使用管理空間數據庫系統。
