Where Leafsnap Washington, 20560 DC 20560

Leafsnap is a series of electronic field guides developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. The free mobile apps use visual recognition software to help identify tree species from photographs of their leaves, and contain beautiful high-resolution images of leaves, flowers, fruits, petioles, seeds and bark. Leafsnap turns app-users into citizen scientists, automatically sharing images, species identifications, and geo-coded stamps of species locations with a community of scientists who will use the stream of data to map and monitor the ebb and flow of flora. The Leafsnap family of electronic field guides aims to leverage digital applications and mobile devices to build an ever-greater awareness of and appreciation for biodiversity.
