Spatial Crowdsourcing: Challenges, Techniques, and Applications
Summary: Survey of spatial crowdsourcing (SC) highlighting spatio-temporal data challenges in task assignment, quality control, incentive design, and privacy. Emphasizes integrating SC with spatial data processing, with case studies and open questions for scalable, privacy-preserving, incentive-compatible platforms.
