GeoHIVE: A DigitalGlobe Community DigitalGlobe Proprietary and Business Confidential 19 Q. How can we prevent submission of false data? Redundancy (“Coverage”) Refers to the number of users who must work on a task before it is “complete”. The greater the coverage level specified by DG, the greater the accuracy of the final dataset produced. Agreement (CrowdRank) CrowdRank measures agreement between a participant’s submissions and the submissions of the rest of the community. Instances of <80% agreement are reviewed manually. Vetting Generate metrics like features created against images reviewed. GeoHIVE: A DigitalGlobe Community DigitalGlobe Proprietary and Business Confidential 20 Who are GeoHIVE Participants?
