CitSci.org (short for 'Citizen Science') provides the training and tools to allow anyone to participate in research on species distributions. For starters, we are focusing on engaing citizen scientists to help map invasive species. We are funded by National Science Foundation (NSF) under grant OCI-0636213. The web site is based on the Global Organism Detection and Monitoring (GODM) system, a joint effort by Colorado State University's Natural Resource Ecology Laboratory, the National Aeronautics and Space Administration (NASA), and the United States Geological Survey (USGS) under the supervision of the National Institute of Invasive Species Science. Technical assistance and map images have been provided by Information Integration and Imaging, LLC (i3).
