【摘要】：政府各部门的业务一般都涉及到各种地理信息数据,其业务管理系统通常需要集成地理信息系统(Geographic Information System,GIS),用于组织、管理、分析和处理各类数据。地理数据来源于地理实体,而在政府管理的过程中对地理实体进行颗粒划分正是顺应了这种社会需求。然而目前的地理信息共享结构仅重视了基于基础地理数据的地理实体的分类表达,较少顾及政府部门的管理需求,造成了基础地理数据成为“背景数据”,支撑政府部门管理的专题地理数据的能力严重不足,成为“信息孤岛”和信息资源大量浪费的重要根源。因此,顾及政府需求的地理信息数据共享模型的研究变得极为重要。本文提出的地理信息共享模型顾及基础地理数据成果和各政府部门的需求,首先通过分析政府的公开信息,研究政府部门的管理内容,提出顾及政府管理部门间的地理实体信息共享中地理实体分类体系,进而得到各部门对地理实体管理的最小颗粒。随后在传统基础测绘数据中引入地理实体的基本信息,构建适用于政府部门间地理信息数据共享的概念模型,从而实现基础测绘数据高频更新的目的,真正完成政府部门间地理信息数据的共享。本文的研究内容和结论主要包括:(1)顾及政府部门管理的地理实体分类体系构建分析政府各部门的行政职能信息,得到本部门管辖的地理实体种类。研究部门内管理地理实体的手段和方式,揭示各部门对地理实体信息的需求,提出顾及政府管理需求的地理实体分类体系,支撑地理实体粒度的划分。(2)政府管理中地理实体基本信息提取首先引入地理实体六要素概念,确定地理实体内涵。然后基于政府管理部门对地理实体的管理需求,探索各政府专业管理部门在管理各类地理实体中所需的地理实体信息。通过分析比较同一地理实体在不同部门中被管理的信息,得到各类地理实体被各政府部门管理的基本信息及特殊信息,服务于地理信息共享模型。(3)顾及政府管理的地理信息数据共享模型建立研究政府部门信息共享机制,分析现有共享机制中存在的问题,探索政府部门对共享数据的需求,建立政府专业管理部门间地理信息数据共享模型。跨越基础地理数据生产部门与政府其他管理部门在基础地理实体和专题管理地理实体之间的鸿沟,假设不同地理实体颗粒之间的桥梁。研究结果表明,基于政府公开信息的地理实体分类体系更能适用在政府间的地理信息共享,结合各部门的管理内容并引入约束不仅顾及到政府部门的需求,同时大幅度加强了各政府管理部门间地理信息数据共享的有效性。
[Abstract]:The business of government departments generally involves various kinds of geographic information data, and its business management system usually needs to integrate GIS (Geographic Information system) for organizing, managing, analyzing and processing all kinds of data. Geographical data comes from geographical entities, and the classification of geographic entities in the process of government management conforms to this social demand. However, the current structure of geographic information sharing only pays attention to the classification and expression of geographic entities based on basic geographic data, and pays little attention to the management needs of government departments, resulting in the basic geographic data becoming "background data". The ability to support the special geographic data managed by the government is seriously inadequate, which is an important source of "information island" and a large amount of waste of information resources. Therefore, it is very important to study the geographic information sharing model which takes into account the government's needs. The geographic information sharing model proposed in this paper takes into account the achievements of the basic geographic data and the needs of various government departments. Firstly, by analyzing the public information of the government, the management content of the government departments is studied. The classification system of geographical entities in the sharing of geographic entity information among government management departments is proposed, and the smallest grain of geographic entity management by each department is obtained. Then the basic information of geographical entities is introduced into the traditional basic surveying and mapping data, and a conceptual model suitable for geographic information sharing among government departments is constructed, so as to realize the purpose of high frequency updating of basic surveying and mapping data. Truly complete the sharing of geographic information data between government departments. The research contents and conclusions of this paper mainly include: (1) considering the classification system of geographical entities managed by government departments, the administrative function information of various government departments is constructed and analyzed, and the types of geographical entities under the jurisdiction of this department are obtained. To study the means and methods of managing geographical entities within the department, to reveal the needs of the departments for the information of geographical entities, and to propose a classification system of geographical entities that takes into account the needs of government management, The basic information extraction of geographical entity in government management firstly introduces the concept of six elements of geographical entity and determines the connotation of geographical entity. Then, based on the management demand of the government management department to the geographical entity, the paper explores the information of the geographical entity that each government professional management department needs in the management of the various geographical entities. By analyzing and comparing the information that the same geographic entity is managed in different departments, the basic information and special information of all kinds of geographic entities are obtained. In view of the geographical information data sharing model managed by the government, the paper studies the information sharing mechanism of government departments, analyzes the problems existing in the existing sharing mechanisms, and explores the needs of government departments for sharing data. A model of geographic information sharing among government professional management departments is established. Bridge the gap between the basic geographic data production department and other government management departments in the basic geographic entity and the thematic management geographic entity, and assume the bridge between the different geographic entity particles. The results show that the classification system of geographical entities based on the open information of the government is more suitable for the geographical information sharing among governments, combining the management content of various departments and introducing constraints not only to the needs of government departments. At the same time, the effectiveness of geographic information data sharing among government management departments has been greatly strengthened.
