Citizen-based sensing of crisis events: sensor web enablement for volunteered geographic information

Citizens as Sensors for Crisis Events: Sensor Web Enablement for Volunteered Geographic Information

A set of developments within the field of geosensors is to engage citizens to act as sensors, thus providing so-called Volunteered Geographic Information (VGI). There is a long tradition of non specialists contributing to the collection of geo-referenced information. Furthermore thanks to recent convergence of greater access to broadband connections, the availability of Global Positioning Syste...

Digital Earth's Nervous System for crisis events: real-time Sensor Web Enablement of Volunteered Geographic Information

Crowdsourcing, Citizen Science or Volunteered Geographic Information? The Current State of Crowdsourced Geographic Information

Citizens are increasingly becoming an important source of geographic information, sometimes entering domains that had until recently been the exclusive realm of authoritative agencies. This activity has a very diverse character as it can, amongst other things, be active or passive, involve spatial or aspatial data and the data provided can be variable in terms of key attributes such as format, ...

A Framework for Web and Mobile Volunteered Geographic Information Applications

This paper proposes a framework to be used in the creation of various volunteered geographic information applications, incorporating both Web-based tools and mobile applications (apps). The framework includes the elements required to customize the information collection, while using a unified structure and interface across Web and mobile platforms. We demonstrate the use of the proposed framewo...

Validation of Volunteered Geographic Information Landuse Change Using Satellite Imagery

Land use change monitoring is one of the main concerns of managers and urban planners due to human activities and unbalanced physical development in urban areas. In this paper, a combination of remote sensing data and volunteered geographic information was used to assess the quality of volunteered geographic information on land use and land cover changes monitoring. For this purpose, the ORBVIE...
