PDA环境下的地下管网GIS数据结构的研究

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,本文提出了将PDA用于地下管线外业调查的研究思路。文章首先介绍了PDA用于管线外业调查的优势,然后针对PDA的特点和地下管线专业要求,设计了一种适用于PDA环境下的地下管网GIS数据结构,最后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,数据处理迅速,界面显示清晰,实践证明该数据结构较好地达到了系统要求。

GIS data structure research of underground pipes net for PDA

In order to change traditional process of underground pipes fieldwork,incorporate ascertainment and survey,digitize data collections and reduce the complexity of pipes fieldwork,research of underground pipes fieldwork based on PDA is put forward.Advantages of pipes fieldwork based on PDA are introduced firstly.Then according to requirement of PDA speciality and pipes field,one GIS data structure of underground pipes net for PDA is designed.At last,it is validated using Shanghai Waigaoqiao Area pipe data.Research results show that the system runs steadily with rapidly data processing and clearly interface displaying,which proves that the data structure can satisfy the system requirement.
