Design and Implementation of Underground Pipeline Outdoor Data Collection Mobile System Based on Android
Guo Pen · 2014
Urban underground pipeline which was called city lifeline is an important part of urban public infrastructure. How to maintain and upgrade these underground pipeline networks rapidly and timely is the most fundamental of all undertakings for urban pipeline management. Field investigation of underground pipeline still depends upon the pencil and paper notebook for data collection. This method is labor-intensive and susceptible to recording and georeferencing errors during transcription. The paper aims to demonstrate how to design and implement a mobile GIS based on android for underground pipeline information investigation. We describe an integrated system developed for data acquisition that is intended to streamline the collection process. Functions of this system include spatial data operation module, data collection module, and communication module. Android 4.0 and Java are employed to develop the system, and key technologies and skills of application developing are introduced. The prototype system has been tested in field trials in Tianjin and the field study demonstrates the noticeable gains in efficiency and precision achieved with the use of the system.
