A tree tour with radio frequency identification (RFID) and a personal digital assistant (PDA)

摘要

A popular tree tour at the University of Washington campus has been automated via RFID and a PDA. The previous 81-tree hardcopy tour has also been updated to include more information on each tree, including digital photos. A survey conducted demonstrates the updated, electronic tree tour is easier to navigate, full of better visuals, and results in less false identifications.
