Leaf Snap
Scientists have developed the first mobile app to identify
plants by simply photographing a leaf. The free iPhone and iPad app, called
Leafsnap, instantly searches a growing library of leaf images amassed by the Smithsonian Institution. In seconds, it returns a likely
species name, high-resolution photographs and information on the tree's
flowers, fruit, seeds and bark. By this summer, it will include all the trees
of the Northeast and eventually will cover all the trees of North
America. Smithsonian research botanist John Kress created the app
with engineers from Columbia
University and the University
of Maryland.
