一种基于ArcGIS的地形图数据库合库方法

A merging method of topographic map database based on ArcGIS

数据库成果是测绘项目最普遍的成果之一。在数字线划图生产过程中,当测图范围较大时,需要划分任务区进行作业,并按任务区存储地形图数据库成果,导致合并处理各任务区数据时流程复杂,采用人工方式不仅耗费大量时间,处理效率也较低。针对此问题,本文提出并介绍了一种基于ArcGIS模型构建器自动、快速分块存储数据库并进行合库的方法,可用于对以数据库形式存储的数字线划图分块库进行合并。经实际使用证明,该方法操作简单,可有效减少人工合库的工作量和出错率。

The database is one of the most popular products from surveying and mapping projects.In the production of digital line graphics in large area,it is very necessary to divide the large mapping area into operation blocks,and store the topographic map database products in operation block,hence,the the merging and processing process is very complex,and too much time is needed but low efficiency when manual method is used.In order to solve the problems above,a method based on ArcGIS Model Builder to automatically and quickly merge the block stored databases is proposed and detailed in this paper,it is mainly used for merging digital line graphic block libraries stored in the databases.It is proved in practice that the method is simple,it can effectively reduce the workloads and error rate from manual database merging.
