摘要
CAD软件和GIS软件对于数据的处理方式有很大的不同之处,使得两种软件对于同一地理对象的描述方式不同,解决CAD数据转换成GIS数据过程中出现的属性或者空间位置信息丢失问题,是两种数据能否转换成功的关键。本文以长春某学校的CAD图为研究对象,通过对CAD数据与GIS数据进行对比分析,将CAD数据转换为GIS数据,对数据进行检查与分析等,利用FME软件实现CAD中DWG数据格式到GIS中Shapefile数据格式进行转换的具体过程,最后完成了CAD数据到GIS数据的无损转换。本次研究充分利用了现有的数据资源,减少了数据整理过程的重复投入,有助于数据成果的及时更新,以期能够促进空间信息产业的不断发展。
There are great differences between CAD software and GIS software in the way of data processing,which makes the two softwares describe the same geographical object differently.The key to successful conversion of the two types of data is to solve the problem of attribute or spatial location information loss in the process of converting CAD data to GIS data.This paper takes the CAD drawing of a school in Changchun as the research object,through the comparative analysis of CAD data and GIS data,converts CAD data into GIS data,checks and analyzes the data,and uses FME software to realize the specific process of converting DWG data format in CAD to Shapefile data format in GIS,and finally completes the lossless conversion of CAD data to GIS data.This research makes full use of the existing data resources,reduces the repeated investment in the data sorting process,and helps to update the data results in a timely manner,so as to promote the continuous development of the spatial information industry.
