摘要
在数字地图的处理工作中,经常需要把DXF文件转换成Shape文件以实现数据的共享。应用现有的转换方法得到的结果往往会出现属性丢失的情况。在ArcGIS中重新添加丢失的属性是一件比较繁琐的事情。因此,掌握DXF文件到Shape文件的无损转换具有实际的意义。深入分析DXF文件和Shape文件的格式,介绍数据的无损转换方法,并讲述如何通过编程来实现数据的无损转换。
Processing in the digital map,convert DXF files to Shape file for data sharing is often need.A pplication of existing methods are the result of the conversion will always be a case of lost property.In the ArcGIS re-add the missing attribute is more cumbersome pieces of things.Therefore,the master file DXF files to lossless conversion Shape of practical significance.This in-depth analysis DXF files and Shape file format,introduced lossless data conversion method,and describes how to programmatically lossless data conversion.
