A new feature is ready for use by all Citizen Science projects running on the SPOTTERON platform: Spot Statistics. The observation of change over time plays an important role in many Citizen Science projects, from hydrology, land coverage or phenology. In the CitSci project "Crowdwater", running on SPOTTERON, Citizen Scientist observe the change of water levels in streams and rivers. As an extension to the Citizen Science smartphone apps, we just released a new feature which introduces a new statistic panel in the detail view of a spot.
