AutoCAD数据在基于Imagis建模中的预处理与质量控制

The AutoCAD data preprocessing and quality control based on imagis

本文根据Imagis建模需要与AutoCAD格式的城市全要素地图数据特征,提出对已有多源数据进行共享,并对此过程进行数据质量控制。通过MapBasic编写程序进行二次开发,实现了数据的预处理过程,生产出符合建模要求的地图数据,极大的减少了人工工作量,提高了生产效率。

According to the needs of key element map data characteristic of city in AutoCAD format the authors propose a methed to share data resources and to control the data quality.Data preprocessing is finished with secondary development of MapBasic.The production efficiency is greatly improved
