A framework of quality assessment methods for crowdsourced geographic information : a systematic literature review

Collaboration is the foundation to strengthen disaster preparedness and for effective emergency response actions at all levels. Some studies have highlighted that remote volunteers, i.e., volunteers supported by Web 2.0 technologies, possess the potential to strengthen humanitarian relief organizations by offering information regarding disaster-affected people and infrastructure. Although studies have explored various aspects of this topic, none of those provided an overview of the state-of-the-art of researches on the collaboration among humanitarian organizations and communities of remote volunteers. With the aim of overcoming this gap, a systematic literature review was conducted on the existing research works. Therefore, the main contribution of this work lies in examining the state of research in this field and in identifying potential research gaps. The results show that most of the research works addresses the general domain of disaster management, whereas only few of them address the domain of humanitarian logistics.

Flood Citizen Observatory: A Crowdsourcing-Based Approach for Flood Risk Management In Brazil

The number and intensity of floods have increased worldwide due to climate change, causing more damage, deaths and economic impacts than any other natural disaster. Coping with this type of disaster requires up-to-date, complete and accurate information about the current state of environmental variables. To make a contribution in this context, this paper proposes a crowdsourcing-based approach for obtaining useful volunteer information for the context of flood risk management. Furthermore, an experimental evaluation was performed in order to verify the effectiveness of this approach

The Use of Volunteered Geographic Information and Crowdsourcing in Disaster Management: A Systematic Literature Review

The number of crisis events around the world has been increasing in the last years and suggests there is a real need to make communities more resilient to them. In addition to providing conventional authoritative data, ordinary citizens and residents in the affected areas are also voluntarily supplying information about the affected areas, in what has been called Crowdsourced or Volunteered Geographic Information (VGI). This paper conducts a Systemic Literature Review aimed at assessing the current state of research in the use of VGI as a source of information to aid the management of disasters. The results suggest there is an increasing body of knowledge of VGI and the way it can improve disaster management. It also reveals gaps in the use of VGI in the research areas of 'preparedness' and 'recovery', as well as the need for more robust case studies and experimental research to support this promising field

Using Wireless Sensor Networks in The Sensor Web for Flood Monitoring in Brazil

Flood is a critical problem that will increase as a result of climate changes. The problem of flooding is particularly challenging over the rainy season in tropical countries like Brazil. In this context, wireless sensor networks that are capable of sensing and reacting to water levels hold the potential of significantly reducing the damage, health-risks and financial impact of events. In this paper, we aim to outline our experiences with developing wireless sensor network for flood monitoring in Brazil. Our approach is based on Open Geospatial Consortium's (OGC) Sensor Web Enablement (SWE) standards, so as to enable the collected data to be shared in an interoperable and flexible manner. We describe the application of our approach in a real case study in the city of São Carlos/Brazil, emphasizing the challenges involved, the results achieved, and some lessons learned along the way
