Tree Atlas takes a BS 5837 tree survey from site visit to signed-off report, in one app for the surveyor and one web desk for the consultancy. Surveyors work on site, camera first. They place each tree on the site map, take photos and voice notes, and record species, measurements and condition. Every suggestion, including the proposed A, B, C or U category, is theirs to accept, edit or override. The app works offline and uploads when you are back in signal. Consultancy owners review the trees on the web desk, manage their team, and issue a BS 5837 report as a PDF with plans, schedules and the method appendix. CSV and DXF exports are included. Available on iPhone, iPad, Android and the web. Start a 30-day free trial and run one live job end to end.
