OpenTreeMap is an open source, web-based system for mapping and managing urban tree inventories. It allows users to search tree data, view ecosystem benefits, add and edit tree records, upload photos, track stewardship activities, and engage the public. Developed by Azavea, it has been used to map trees in many cities. It provides tools for data collection, management, and public participation in urban forestry.
