The Design and Realization of Personal Computer Based Topographic Data Input System
-
摘要: 本文充分利用现有地图和航空象片资料,并借助于联机立体坐标量测仪、数字化桌(仪)和微机等设备,进行了地物、地貌的数据采集。文中叙述了地物、地貌既简单又实用的数据结构,解决了数据采集时的粗差检测、联机编辑和图形监视等难点,从而为数字测图系统提供了正确和完整的原始数据。Abstract: This system,by making use of the digitizing table and the sterocomparator for data input,designs a simple structure for the topographic data,and solves such problems as blunder detection,on-line editing,and graphic monitoring.So,this system can provide the Digital Mapping System with correct and integrated data.
