基于嵌入式GIS的管线外业调查系统的开发

Development of pipes fieldwork system based on embeded GIS

为了改变传统的地下管线外业调查流程,将探查和测量合为一步,实现数据采集的数字化,降低管线外业调查的复杂度,本文使用Arcpad软件的二次开发工具ArcPad Application Builder开发了基于嵌入式GIS的管线外业调查系统。文章在系统分析设计的基础上重点阐述了系统功能的实现,通过内置功能的定制和VBScript编程实现自定义功能的方法开发了系统的各个功能。在应用实例的分析中使用上海外高桥区域管线数据进行了验证,结果系统运行稳定,界面显示清晰,较好地满足了PDA环境下地下管线外业调查的需求。

In order to change traditional process of underground pipes fieldwork, incorporate ascertainment and survey, digitize data collections and reduce complexity of pipes fieldwork, pipes fieldwork system based on embeded GIS is developed by ArePad＇ s secondary development tool -ArcPad Application Builder. The paper mainly illustrates how to realize system functions based on system＇ s analyse and design, all the system functinns are realized by customizing built-in commands or making use of VBScript to programme for user-defined commands. The system is validated using Shanghai Waigaoqiao Area pipe datas as an example. Research results show that system runs steadily and interface displays clearly, which can properly satisfy the need of underground pipes fieldwork based on PDA.
