Mobile Pollution Mapping in the City
نویسندگان
چکیده
Mobile computing has the potential to allow both experts and the public to collect and understand environmental data such as pollutants in urban areas. We describe an experimental system—eGS—that allows users to explore a city area while collaboratively visualising a common atmospheric pollutant— carbon monoxide—in real-time. Users carry a networked tablet PC. Using GPS and an attached sensor, a map shows pollutant values as a colourcoded trail as the user moves around the city. Users may take photographs of pollution-significant situations that are referenced against their current map location. Pollutant readings and photographs appear on all users’ maps as shared information for potential collaboration. We report on lessons learned and design issues arising from the implementation and us of this research prototype. In particular, we question some assumptions regarding the use of map-based representations with transient environmental information.

Mapping of Environmental Pollution in Urban Areas with Gis
Environmental pollution in urban areas has resulted in the design of monitoring and decision-making systems. These systems are supported by the information systems that can manage spatial dynamics of pollution processes. Due to a wide range of data, which are necessary for modeling of spatio-temporal phenomena, new methods of data collection and management have to be created. This paper describ...
متن کاملEstimating Urban Ultrafine Particle Distributions with Gaussian Process Models
Urban air pollution have a direct impact on public health. Ultrafine particles (UFPs) are ubiquitous in urban environments, but their distribution are highly variable. In this paper, we take data from mobile deployments in Zürich collected over one year with over 25 million measurements to build a high-resolution map estimating the UFP distribution. More specifically, we propose a new approach ...
متن کاملA Mobile Crowd-Sensing Platform for Noise Monitoring in Smart Cities
Modern cities are moving towards novel approaches for urban sustainability for improving citizenship’s life quality, thus aiming at the Smart City model. Environmental and mobility issues represent two key areas where policy makers address their interventions and, amongst them, noise pollution is one of the most significant causes of public concern. However, noise monitoring campaigns are expen...
متن کاملEar-Phone: A context-aware noise mapping using smart phones
A noise map facilitates the monitoring of environmental noise pollution in urban areas. It can raise citizen awareness of noise pollution levels, and aid in the development of mitigation strategies to cope with the adverse effects. However, state-of-the-art techniques for rendering noise maps in urban areas are expensive and rarely updated (for months or even years), as they rely on population ...
