EcoHack is a global event that aims to improve our environment using technology and great ideas, where participants build tools, create visualizations, and tell stories about the environment and science. The event has grown into a global phenomenon happening in multiple locations worldwide, including New York, San Francisco, São Paulo, and Madrid, on May 9-10. Past events have featured diverse projects, such as creating data visualizations, building kites, and mapping forest loss, showcasing the flexible format and meaningful outcomes of the event. This year, CartoDB will provide free resources to participants, including a free workshop on how to use their platform for hackathons, further enhancing the experience.
