发布时间：2018-08-09 18:12
【摘要】：本文是在辽宁省辽阳市第二次全国土地调查项目的支撑下，以太子河区为对象进行研究，在GIS和土地调查的理论技术支持下，系统研究了建设县一级的农村土地利用数据库的理论方法，探讨了如何利用已有土地更新调查数据，并且研究了数据库建设过程中的几项关键技术。具体内容包括： （1）分四个阶段探讨了县级农村土地调查数据库建设的方法，即：内业数据采集、外业实地调绘、内业数据整理、数据库建设； （2）以土地更新调查数据库为基础，设计了一套数据库建设技术路线，对原有技术路线分别进行了数据源、属性数据采集、数据库结构、数据入库等几个方面的改进； （3）为了更好的利用已有地籍信息，，本文通过实例研究了第二次土地调查与土地更新调查数据衔接的关键技术，包括坐标系转换、属性继承以及数据格式转换； （4）探讨了本次数据库建设的关键技术，主要包括影像解译、椭球面积计算以及数据拓扑； （5）详细介绍土地调查中的误差来源，具体分析每个过程中数据质量问题的来源，并提出质量控制方法。
[Abstract]:Supported by the second national land survey project in Liaoyang City, Liaoning Province, this paper takes the Taizi River District as an object of study, with the support of GIS and the theory and technology of land survey. This paper systematically studies the theory and method of constructing the rural land use database at the county level, discusses how to utilize the existing land renewal survey data, and studies several key technologies in the process of building the database. The specific contents are as follows: (1) the methods of constructing rural land survey database at county level are discussed in four stages, that is, data collection, field mapping, data collation and database construction; (2) on the basis of land renewal survey database, a set of technical route of database construction is designed, and the original technical route is improved in several aspects, such as data source, attribute data collection, database structure, data input and so on. (3) in order to make better use of the existing cadastral information, this paper studies the key technologies of the data connection between the second land survey and the land update survey, including coordinate system transformation, attribute inheritance and data format conversion. (4) the key technologies of the database construction are discussed, including image interpretation, ellipsoid area calculation and data topology. (5) the error sources in land survey are introduced in detail. The source of the data quality problem in each process is analyzed, and the quality control method is put forward.
