PDA 的野外数据采集成果预处理系统的设计与开发

摘要

为了适应测绘科学技术的信息化、自动化应用发展的需求，掌上电脑（ Personal Digital Assistant ，PDA）在测绘野外数据采集得到广泛应用，本文运用面向对象的思想设计并开发了野外数据采集成果预处理系统。该系统主要由数据通信、数据记录与检查、测量数据概算、原始成果记录表格自动生成、数据格式转换五个模块组成。将该系统与全站仪结合可实现野外测量数据的高效自动化数据采集及预处理概算，为内外业数据处理一体化奠定基础。%In order to adapt to the requirement of information and automation application development of surveying and mapping sci -ence and technology .PDA is widely used in surveying and mapping field data collection , In this paper , the field data acquisition and data processing system are designed and developed based on the idea of object -oriented.The system is mainly composed of data com-munication , data records and inspection and surveying data estimate , the original records table automatically generate , data format conversion.The system combined with total station can realize automatic data acquisition and preprocessing of the field surveying data estimates and lay the foundation for surveying data automatically processing .
