基于EPS三维测图系统制作DLG的优势分析及成果数据格式转换研究

Advantage analysis of DLG production based on EPS 3D mapping system and research on format conversion of results data

基于EPS三维测图系统制作DLG,相比传统作图方式有着数据规范、入库简单的优势。为提高数据利用率,实现测绘成果信息化,减少数据之间转换的丢失,本文分析了EPS三维测图系统制作DLG的优势,研究了EPS三维测图系统的EDB格式数据与目前测绘行业流行的数据格式转换的过程以及转换过程中发现的问题。

Making DLG based on EPS 3D mapping system has advantages of data specification and simple warehousing process.In order to improve the data utilization rate,realize the informatization of surveying and mapping results,and reduce the loss of data transformation,this paper analyzed the advantages of EPS 3D mapping system in making DLG,studied the conversion process from EDB format data of EPS 3D mapping system to the popular data format in the surveying and mapping industry and the problems found in the conversion process.
