State And Trends In Mobile Observation Applications, Denis Havlik, Gerald Schimak
State And Trends In Mobile Observation Applications, Denis Havlik, Gerald Schimak
International Congress on Environmental Modelling and Software
The stellar growth of the smartphones and nearly gapless mobile network coverage in urban and suburban areas has widely extended the potential of the citizens' observatories. The possibility to easily record observations made by mobile citizens, and to automatically enrich this information using the built-in and external sensors sounds like a dream come true of the scientists and decision makers alike. However, in 2013 only a tiny portion of the potential users really participated in the citizen observation programs and the usability of the received information is often below expectations. The learning curve is often too high, sensor quality too …
Involving Citizens Into Mapping Of Illegal Landfills And Other Civic Issues In The Czech Republic, Miroslay Kubásek, Jiři Hřebíček
Involving Citizens Into Mapping Of Illegal Landfills And Other Civic Issues In The Czech Republic, Miroslay Kubásek, Jiři Hřebíček
International Congress on Environmental Modelling and Software
Today's smartphones can unlock the full potential of crowdsourcing and take eParticipation to a new level. Users are allowed to transparently contribute to complex and novel problem solving. Engagement of citizens is still challenging but the proliferation of smartphones with geolocation have made it easier than before. The paper introduces the environmental project called ZmapujTo.cz. This project is primarily intended to fight illegal waste dumps in the Czech Republic. The idea is to use the potential awareness of the broader public about the environmental and economic drawbacks of illegal landfills. We developed a more efficient version of the web portal …

Crowdsourcing In Early Warning Systems, Ulrich Meissen, Frank Fuchs-Kittowski
International Congress on Environmental Modelling and Software
The use of mobile devices as an effective and targeted way for alerting the public in cases of disasters has become an important part of future infrastructures for early warning and disaster management. In contrast to classical alert approaches such as TV, Radio and sirens that are offering solely a one-directional communication the use of smart phones opens new potentials such as feedback mechanisms that support more precise warnings and adapted response actions. In this context crowdsourcing techniques show a high potential as an effective measure to meliorate the data basis for predictions and augment warnings. This paper discusses the …
A Bayesian Maximum Entropy Scheme For The Assimilation Of Mobile Recordings With Simulations Of Urban Micrometeorological Data, Uwe Schlink, Gabi Fischer
A Bayesian Maximum Entropy Scheme For The Assimilation Of Mobile Recordings With Simulations Of Urban Micrometeorological Data, Uwe Schlink, Gabi Fischer
International Congress on Environmental Modelling and Software
This paper proposes a framework for assimilating urban temperature measurements with simulations of an urban micrometeorological model. Data assimilation, a technique that incorporates observations into a computer model of a real system, is commonly applied in global and regional weather forecasting and an emerging issue in urban meteorological modelling. For that purpose, we suggest applying a novel approach, the Spatiotemporal Epistemic Knowledge Synthesis (SEKS). It combines simulations of a thermodynamic urban climate model, as general knowledge base, with a model output statistics (MOS) of observations, as site-specific knowledge base, by means of Bayesian Maximum Entropy (BME) inference resulting in posterior …
