现势大比例尺地形图在城镇地籍调查中的应用

Application of current large-scale topographic map in urban cadastral inventory

在第二次全国土地调查和地籍数据库建设的背景下,必须在规定时间内完成全国地籍数据库的建设工作,急需一种切实有效的方法提高城镇地籍调查工作的效率和质量。本文分析了现行城镇地籍调查流程存在的问题,提出了在城镇地籍调查中应用现势大比例尺地形图的方法,同时提出了准界址点的概念。解决了历史底图现势性差、非独立宗地和大面积宗地指界困难、指界人无法现场指定界址点的问题,改进了地籍调查流程,经实际工程验证,该方法可以大幅度提高地籍调查工作的效率和质量。

To meet the second national land inventory and the construction of cadastral database, the national eadastral database has to be completed within the stipulated time. Therefore, it is necessary to use a method to improve the efficiency and quality of urban cadastral inventory. This paper analyzes the problems in the present urban cadastral inventory process, introduces a method on how to use current large scale topographic map in this work, and points out the concept of quasi-boundary. Moreover, the problems in historical base maps, such as poor in current situation, non-independent, large parcels and boundaries hard at identification on site, can be solved. The related project cases have been proved that this method can improve the mentioned work significantly.
