Cos4Bio is one of the eleven services that the Horizon2020 project is developing to boost citizen science technologies. It is a service that integrates biodiversity observations from multiple citizen observatories in one place. This means that you will save time in the species identification process and get access to an enormous number of observations. We would like to know if you find that Cos4Bio is easy to use and how you would improve it! That is why we invite you to do a short exercise to test the prototype and share your feedback on our Miro board! We will take into account your comments in Cos4Bio development. You do not need to have previous knowledge. This activity is open to everyone interested in citizen science, experienced or not. Find all the information on this link:
