    Agenda

    Participatory sensing

    Our activities in the field

    Challenges and approaches

  • Participatory Sensing

  • 24/09/2015 4

    People with their devices as sensors

    Measuring enables meaningful actions.Are people good as sensors?

    We are everywhere, carrying powerful mobile devices.

    What is participatory sensing?

    Citizens providing environmental observationswith the help of mobile technologyNew, emerging paradigm in environmental monitoringCrowdsourcing

    Spectrum: experts / trained volunteers / ordinary citizens

    Related: Citizen ScienceScientific work undertaken by members of the general public,often in collaboration with or under the direction of professionalscientists and scientific institutions (Oxford English Dictionary)

    Citizen Science: A few examples

    Benefits of participatory sensing

    Cost-efficient extension of spatial and temporal data coverageNear real-time situation awareness for improved decision makingCombining with other sources, finding correlations (validation)Example:

    Remote sensing techniques have already proven their efficiency inforest monitoring.However, they lack adequate ground reference data, because of thehigh costs of the required field work, the lack of field personnel andlegislative restrictions relating to data privacy.Moreover, data is often obsolete since acquisition of frequentobservations is not realistic for economic and practical reasons.

    Forest Biomass Analysis Pilot

    55 plots visited over 10 sites in NovemberDecember 2014Basal area measured with Relasphone

    The collected data was compared to reference forest inventorydata for accuracy assessment

    Comparison of Relasphone measurements to reference data over55 plots showed a good agreement (R2 = 0.94)

  • Challenges and approaches

  • 24/09/2015 23

    Primary Challenges

    Citizen Engagement: Generating and sustaining citizen engagementand motivation.Upscaling: Responding to the requirement for sufficient data volumeswith adequate geospatial and temporal distribution, and supporting alsodynamic needs for observation data from specific area and time, forexample aligning with satellite overpasses.Data Quality: Ensuring data accuracy and reliability; Learning aboutthe actual data quality, reaching the desired data quality level, andproving and showing the achieved data quality.Commercial Sustainability: Achieving commercial sustainability forthe Citizen Observatory activity, through the capability to provide end-users benefit and added value.Legal Framework: Ensuring compliance with legislation, regulationsand other boundary conditions. Managing issues of observer privacy,data ownership and forest owners data privacy.

    Citizen engagement

    Sustained motivation: incentive for the observation workreward: recognition, status, contribution visibility, information,service value, money etc.socializing: involve people, let people connectparticipation: let users feel part of a big common effort, offerbackground info and motivationreminders: ask people for certain types of observations in limitedareas; offer motivation

    GAMIFICATION!Reporting observations needs to be simple, easy and fast

    Minimize startup effort, offer easy setup. Do not require registrationfor basic features. Provide smooth mobile user interface.

  • 24/09/2015 25

    Onwards

    Participatory Sensing: Vision for 2020?Citizen Science is a widely accepted method forcollecting in-situ data with good quality as asupplementary data source for multiple purposes.

    Leap towards professional andeconomically sustainable operations.
