About
Second Look teaches you to see the creek damage people usually miss, then tests you on it. Your score travels with every observation you make, so a city knows how much to trust it.
Professional stream surveyors pass a test before their data counts. Some volunteer programs certify people for a method, such as water chemistry. None we know of measures how well each volunteer sees each feature, or keeps that score with every observation. Second Look gives volunteers a short lesson and a sixteen-photo test on four kinds of creek damage, and saves the score with every observation they make.
The test is a usability study with a pre-registered analysis plan. Half the people see the lesson first and half see it after. We publish the result either way.
Built for the OneAquaHealth hackathon, track 3, AI-Supported Assessment. It is set up for Berkeley the way a follower city would set it up, though the city has not adopted it and no volunteer has used it at a creek yet. Strawberry Creek is the creek we worked through.
