Three asks. None require talking to us first.
The platform is proprietary; the data is public.
Report litter on the live map.
Open Grime Ward beta — open it, find litter you pass anyway, and report it: photo, location, reachability tags (could a small ground robot get to this?), optional hazard pins. Each report becomes part of the public CC-BY-SA-4.0 dataset once you explicitly choose to share it. Private journal visits stay on your device.
Sign-in is one tap with your Google or Apple account — no password, and we never send you email.
Log your cleanups — especially if you run one.
Record the date and amount of a completed cleanup. Reports distinguish cleanup activity from observed litter condition; the number of cleanups alone does not establish how fast litter accumulates.
If you organize cleanups, create an organization on the map: volunteers' pickups count toward your org, volunteer hours are recorded, and your history exports in a funder-shaped report.
Cite, mirror, or build on the public dataset.
The observation corpus is published under CC-BY-SA-4.0 as versioned GeoJSON snapshots — observations plus provenance metadata. Download the current snapshot from the map's ⓘ Sources sheet, which also cites every upstream source per watershed (DC 311, OpenLitterMap, EPA ATTAINS, USGS WBD) with fetch dates.
Use it, redistribute it, train on it. Contributor emails are never published.
No email capture. No "join the waitlist." If you want to follow along, read the build log.
