【摘要】：目前，数字城市是城市信息化建设的主要热点，数字城市是社会生产力跨越式发展和城市可持续发展的重要方法，是一个城市提高综合竞争力的必然选择，是不断推进城市信息管理体系改革，，优化城市资源配置，节约基础设施建设资金，健全信息资源的市场化建设机制，实现城市信息资源充分有效地融合的新型有力的工具。于此同时作为数字城市的数据支持体系的基础地理信息系统的应用研究引起了GIS学者的高度关注。如何使数字城市和基础地理信息系统这两者有效地结合起来成为各国学者研究的焦点。因此，如何建立基础地理信息系统成为本文研究的一个重点，在此基础上进行数据管理的研究。由于基础地形数据库、框架要素和地理实体数据库、地名地址数据库是基础地理信息数据库中比较关键的数据库，所以成为本文研究的另一个重点。本文围绕数字金华基础地理信息系统的项目建设，首先探讨了数字金华的相关技术，包括GIS技术、RS技术、GPS技术、LBS技术、SIG技术、空间数据库技术；接下来分析了基础地理数据采集技术，包括采集技术体系、加工技术体系、采集流程；然后再对基础地理信息系统开发的关键技术进行了分析，包括组件式GIS技术、WebGIS技术、空间数据引擎技术、空间数据互操作技术。通过对项目建设的基础情况的分析，提出了目前的数据现状、数据存在的问题，对数据需求进行了调研和分析。介绍了基础地形数据库、框架要素和地理实体数据库、地名地址数据库，介绍了了金华市基础地理信息系统。系统为GIS工作者分析数据、提交数据成果提供了有效的方法。
[Abstract]:At present, digital city is the main focus of urban information construction, digital city is an important method of social productivity leapfrog development and urban sustainable development, it is an inevitable choice for a city to improve its comprehensive competitiveness. It is a new powerful tool to continuously promote the reform of urban information management system, optimize the allocation of urban resources, save capital for infrastructure construction, perfect the market-oriented construction mechanism of information resources, and realize the full and effective integration of urban information resources. At the same time, the application of GIS as the data support system of digital city has attracted great attention of GIS scholars. How to effectively combine digital city and basic geographic information system (GIS) has become the focus of scholars all over the world. Therefore, how to establish the basic Geographic Information system (GIS) has become a focus of this paper, and on the basis of this, data management is studied. Because of the basic topographic database, frame elements and geographic entity database, the toponymic address database is the key database in the basic geographic information database, so it becomes another focus of this paper. This paper focuses on the construction of Digital Jinhua basic Geographic Information system (DGIs). Firstly, it discusses the related technologies of Digital Jinhua, including GIS technology, RS technology, GPS technology, LBS technology, SIG technology, spatial database technology. Then it analyzes the basic geographic data acquisition technology, including the collection technology system, the processing technology system, the collection process, and then analyzes the key technologies of the basic GIS development, including the component GIS technology and WebGIS technology. Spatial data engine technology, spatial data interoperability technology. Based on the analysis of the basic situation of the project construction, this paper puts forward the current data situation, the problems existing in the data, and makes an investigation and analysis of the data demand. This paper introduces the basic topographic database, frame elements and geographic entity database, toponymic address database and Jinhua basic geographic information system. The system provides an effective method for GIS workers to analyze data and submit data results.
