Open Quadrat makes open-source, offline-first apps for fieldwork; its Plants Map app records plants and measures trees, and is in public beta.

Landing page captured for the 2026-11-11 issue.

For: Field ecologists, foresters, NGOs, students, and landowners
Worth noticing: Tree measurements can use a phone, stride, arm spans, or a bank-card photo; exports include CSV, KML, GeoJSON, and Shapefile.

Field notes

Plants Map's listed record fields include species, location, height, canopy, girth, health, and photos; users can walk a site boundary or import one as KML. The homepage lists exports to CSV/Excel, KML, GeoJSON, Shapefile, and Plan Studio, and says exports are free in every edition. For its free cloud edition, the site says data stays on the phone and in the user's Google Drive, with sync waiting for a connection.
