City probe: The crowdsourcing platform driven by citizen-based sensing for spatial identification and assessment

Abstract

In this paper, we introduce the City Probe, a participatory sensing system that can quantify citizens’ perception of places. City Probe recruits citizens to participate in the spatial identification and assessment. It includes the smartphone APP that allows citizens to photo and rate their locational characteristics according to some issues. Their contributions, with latitude and longitude coordinates, would be uploaded and quantified in the City Probe cloud platform and visualized into a weighted map that reveals the collective out-come based on citizens’ cooperation. Pilot studies in the campus have been accomplished. The collected geospatial data is represented in terms of the weighted map for disclosure of Information and decision-making supports.
