The Ecological Atlas communicates the seasonal changes of the natural world and serves as a comprehensive design and visualization tool. It bridges art, science, design, and technology, and connects the power of data and technology to help designers, planners, and anyone interested in better understanding and transforming the environment. By using intuitive, graphic mappings that can convey changes in bloom times, deciduous tree patterns, produce seasonality, animal migrations, and other time-dependent phenomena, the EcoAtlas facilitates a comprehensive understanding of the environment.
