Cognitive Surplus Citizen The Urban Forest Map

摘要

For 15 years, thousands of amateur ornithologists throughout North America (60,000 in 2011) have participated in the Great Backyard Bird Count, providing researchers with data about the survival rates, migration paths, and secret lives of birds they would never have been able to gather on their own.. Similarly, Galaxy Zoo, an interactive and multi-project resource for enterprising astronomers, engages amateur stargazers around the world when classifying galaxies from images taken by the Hubble SpaceTelescope.
