Digital resources for conducting virtual street tree surveys with street-level photography

These digital resources can be used to facilitate virtual street tree surveys. Four files are included: (1) GSV_overview_document – a user manual describing the data collection process using Google Street View to inventory trees; (2) DBH_reference_guide – reference material for visually estimating tree diameter at breast height (DBH); (3) Tree_ID_guide – identification guide for the most common street trees in the Midwest U.S.; and (4) Tree_Data_Collection_Form – a spreadsheet for recording street tree data.
