基于ArcGIS的基础测绘成果DLG数据入库

摘要

为了解决DWG格式数据不能在空间地理信息数据库中发挥作用的问题,利用ArcGIS的Spa-tial ETL Tool工具实现DWG到SHP的数据格式转换,按照国家技术规范和招标文件要求,实现了DWG数据生产到数据入库,解决了由地形数据到空间地理信息数据的转换,扩展了DLG数据在数字城市等领域的作用.对数据库结构设计,数据库预处理,数据格式转换、入库、质量控制、融合等技术环节进行了阐述.%In order to solve the problem of DWG format data in spatial geographic information database,this paper used ArcGIS Spatial ETL Tool to implement DWG to SHP data format conversiori,as well as storage the DWG data into database according to the national technical specifications and the tender document.This study converted the terrain data to spatial geographic information,extended the DLG data in the field of digital city,etc.Furthermore,the paper elaborated the techniques of database structural design,database pretreatment,data format transition,storage,quality control,data fusion etc.
