Now this is a PERFECT application for land surveyors everywhere.  Identify trees while surveying, using just your phone!!

 Leafsnap is a new free app that identifies trees.

The next time you are out on a survey identifying trees, take a shot of a leaf and this little wonder will identify its tree and give all kinds of information about it.

Leafsnap is the first in a series of electronic field guides being developed by researchers from Columbia University, theUniversity of Maryland, and the Smithsonian Institution. This free mobile app uses visual recognition software to help identify tree species from photographs of their leaves.

Leafsnap contains beautiful high-resolution images of leaves, flowers, fruit, petiole, seeds, and bark. Leafsnap currently includes the trees of New York City and Washington, D.C., and will soon grow to include the trees of the entire continental United States.

This website shows the tree species included in Leafsnap, the collections of its users, and the team of research volunteers working to produce it.

very useful..thanks Jobber

Hello Justin,

very worthwhile app...I take photos of all evidence found. Recently in Oklahoma I was searching for corners. The record from 1940s showed ties to an elm tree,can't remember the diameter...the trees were gone,nothing but fields and section line roads. There was an overgrown area near record bearing and distance. Inside that area I found a stump with a clean cut and branches growing out of it. Took pictures of the stump and close ups of the leaves. An app would certainly add to real time information.


Thanks, Paul
