A photo taken in the field helps scientists and citizens to document changes in landscape, wildlife habitats, impacts of drought and flood and fire, and so on. This Geo-referenced Field Photo Library is a citizen science and community remote sensing data portal, where people can share, visualize and archive field photos in the world. Users can upload, edit, query and download geo-referenced field photos in the library. All photos are also linked with satellite image series images (MODIS), so that people can see the changes over time.
