【摘要】：数字城市建设是空间信息基础设施的重要组成部分，是经济社会信息化发展的基础平台。基础地理信息数据库作为数字城市的重要空间信息模块，通过不同模型结构对城市的多源数据进行有效、合理的整合，为各类与地理位置有关的应用部门提供统一的、多种尺度的空间和时间维度上的地理信息，，从而服务于多种领域。本文以某市数字城市建设项目中1：1000和1：10000两种比例尺四种类型数据为源数据，根据地理信息数据的分层方式、分类编码、图形的表现形式的不同，研究了数据入库方法和内容。内容包括原始数据收集、对比例尺和类型不同的原始数据分别进行检查分析，源数据数据预处理，数据库结构设计，地理信息要素的编辑和属性录入、数据的质量检查以入库及MDB成果导出。基于以上研究的内容，根据项目的实际应用，研究基于图层和基于厚度的两种数据导入方法以及数据预处理后入库编辑和直接入库编辑等入库方法，为数字城市的基础数据库建设提供方法论。
[Abstract]:The construction of digital city is an important part of spatial information infrastructure and a basic platform for the development of economic and social information. As an important spatial information module of the digital city, the basic geographic information database can effectively and reasonably integrate the multi-source data of the city through different model structures, and provide uniform information for all kinds of application departments related to geographical location. Multiple scales of spatial and temporal dimensions of geographic information, thus serving a variety of fields. This paper takes four types of data of scale of 1: 1000 and 1: 10000 as source data in a digital city construction project of a certain city. According to the layering of geographic information data, the classification and coding, and the different expression forms of graphics, The methods and contents of data storage are studied. The contents include raw data collection, checking and analyzing raw data of different scales and types, preprocessing of source data, design of database structure, editing of geographical information elements and input of attributes. The quality of the data is checked and exported to the database and MDB results. Based on the above research content, according to the practical application of the project, two data import methods based on map layer and thickness are studied. To provide the methodology for the basic database construction of the digital city.
