Build flow

01 · Problem
Planting drives report trees planted, but nobody knows how many are alive a year later.
02 · Solution
Volunteers geotag each sapling with a photo, revisit on reminders, and a vision model checks if the plant looks alive; dashboards show survival rate.
03 · Build
  1. 1Build the planting capture flow
  2. 2Store points with photos
  3. 3Schedule revisits
  4. 4Chart survival
04 · Demo
Show a map of 50 saplings with survival colours and a revisit photo.
