OpenTreeMap is software for collaborative, geography-enabled urban tree inventory. The software enables the public, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population. Users can search for trees, add trees to the system, edit existing tree information, or upload tree photos. The system automatically calculates a tree's ecosystem benefits based on its species and diameter. OpenTreeMap can be used in a single municipality or to cover a broader geographic region with many communities, anywhere in the world. This software also exists as a subscription-based system.
GRIFIN (Geospatial Reference Interface For Internet Networks) is a design for a new network service providing information via the geo-spatial-temporal context. It is different from other existing Internet services, with strong focus on interoperability, decentralized architecture, and visualization.
