【摘要】 GPS基线网数据处理系统包括基线网优化设计、基线数据提取与检核、三维无约束平差、三维基线向量向二维基线向量的转换、二维约束平差、高程拟合、坐标系统转换和数据库管理系统等子系统,系统还附加地面三角网、三边网、导线网、边角网、水准网和二十种常用测量计算程序。本系统基于Windows 98 操作系统,采用面向对象的程序设计语言,具有良好的人机界面,使用方便,可直接处理多种基线处理软件的基线文件。系统的平差程序采用压缩存储技术,在现有微机内存条件下,可一次处理成千上万个控制点。系统采用了图象技术,在图上可以选取基线进行检核、选取独立基线进行平差、平差后显示控制网图和误差椭圆图,在图上还可以进行查询各种平差成果。更多还原

【Abstract】 The system includes many subsystems such as baseline network design optimizing、data access and check、unbinding adjustment in 3-D 、baselines in 3-D transforming to that in 2-D 、binding adjustment in 2-D、elevation fitting 、coordinates transforming and database management system and more that 20 calculating programs in surveying of triangulation、trilateration、traversing、leveling . Based on Windows 98,the system in designed with objective oriented programming language which has the features of good man-machine boundary and convenient uses ,so it can process multi-types of baseline files .The system employed packed storing and visual techniques to process thousands upon thousands of control points、and to check、select、draw、adjust the baselines graphically . Meanwhile , the results can be inquired from charts.更多还原
