地形图图形输出系统GOSTM的设计与实现

Design and Implementation of Graphic Output System for Topographic Maps (GOSTM)

摘要: 本文在分析现有数字地形图图形输出的前提下,提出了地形图图形输出系统GOSTM(Graphic Output System for Topographic Maps)的设计原理,并详细介绍了其系统结构,各种模块的基本功能及其数据接口。本系统与地形图数字化系统DSTM(Digtial System for Topographic Maps)联接已成功地实现了地形图图形输出。

Abstract: Based on having analysed current graphic output of digital topographic maps,the design principle of Graphic Output System for Topographic Maps(GOSTM) is proposed in this paper. Fundamental functions of each module, system structure and data interface will be given in detail. This system has implemented graphic output of topographic maps,connect-ing with Digtial System for Topographic Maps (DSTM).
