Designing an Android-Based Application for Geohazard Reduction Using Citizen-Based Crowdsourcing Data

الملخص EN

Application development based on mobile platform is regarded as one of the major trends in information communication technology.

However, only a few cases of mobile application are available for geohazard reduction using citizen-based crowdsourcing data.

With the development of geohazard informatization and the rapid progress of mobile technology, the design and implementation of phone-based applications that could be used to monitor and prevent geohazards have been received increasing attention.

Aiming at minimizing the threat of geohazards to people’s lives and assets, this paper presents an android-based application named Geohazards Group Measurement and Guards against System (GGMGAS).

Local villagers use the GGMGAS to collect field data, including photos and videos, and transmit them to a database server.

Therefore, the efficiency and stability of the data exchange between the mobile phone and the database server is very important.

A design method and system solution of a data-exchange scheme was designed based on the WebService technology.

Through trial operation, it has been found out that this data-exchange scheme could greatly improve the communication efficiency and the stability of collected field data.

Practice has proved that this method based on citizens’ crowdsourcing data can effectively reduce the losses caused by geohazards.
