【摘要】：數(shù)字城市建設(shè)是空間信息基礎(chǔ)設(shè)施的重要組成部分，是經(jīng)濟(jì)社會信息化發(fā)展的基礎(chǔ)平臺�；A(chǔ)地理信息數(shù)據(jù)庫作為數(shù)字城市的重要空間信息模塊，通過不同模型結(jié)構(gòu)對城市的多源數(shù)據(jù)進(jìn)行有效、合理的整合，為各類與地理位置有關(guān)的應(yīng)用部門提供統(tǒng)一的、多種尺度的空間和時間維度上的地理信息，，從而服務(wù)于多種領(lǐng)域。 本文以某市數(shù)字城市建設(shè)項目中1：1000和1：10000兩種比例尺四種類型數(shù)據(jù)為源數(shù)據(jù)，根據(jù)地理信息數(shù)據(jù)的分層方式、分類編碼、圖形的表現(xiàn)形式的不同，研究了數(shù)據(jù)入庫方法和內(nèi)容。內(nèi)容包括原始數(shù)據(jù)收集、對比例尺和類型不同的原始數(shù)據(jù)分別進(jìn)行檢查分析，源數(shù)據(jù)數(shù)據(jù)預(yù)處理，數(shù)據(jù)庫結(jié)構(gòu)設(shè)計，地理信息要素的編輯和屬性錄入、數(shù)據(jù)的質(zhì)量檢查以入庫及MDB成果導(dǎo)出。基于以上研究的內(nèi)容，根據(jù)項目的實際應(yīng)用，研究基于圖層和基于厚度的兩種數(shù)據(jù)導(dǎo)入方法以及數(shù)據(jù)預(yù)處理后入庫編輯和直接入庫編輯等入庫方法，為數(shù)字城市的基礎(chǔ)數(shù)據(jù)庫建設(shè)提供方法論。
[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.
