2018–2021 · Street tree inventory tool design

Treetective is a web app that lets municipal and community foresters remotely inventory street trees. The work was funded by a USDA SBIR grant.

City view — Customers divide their geography into arbitrary survey areas, each assigned to an individual surveyor

Survey area — The survey area map indicates known trees and surveyed/unsurveyed locations

Step one of the tree inventory flow — Surveying a location begins by clicking a tree in the panorama viewport

Step two of the tree inventory flow — Clicking the same tree in an adjacent panorama viewport then triangulates its location

Step three of the tree inventory flow — The surveyor then fills in genus and other observable characteristics

Step four of the tree inventory flow — Onscreen calipers make measuring diameter a breeze

Step five of the tree inventory flow — And canopy size as well

Location done — Once a location is surveyed, its trees can still be edited

A screen from the admin site — Admins can customize their installation to regional patterns, including genus and species
