About Us

PhillyTreeMap is a web-based map database of trees in the greater Philadelphia region. The wiki-style database enables non-profits, government, volunteer organizations, and the general public to collaboratively create an accurate and informative inventory of the trees in their communities.   

PhillyTreeMap was built by Azavea, a Philadelphia-based software design and development firm specializing in Geographic Information Systems (GIS) technology, with funding from the United States Department of Agriculture (USDA). In 2010, Azavea was awarded a USDA Phase I Small Business Innovation Research (SBIR) grant to develop a prototype of new data management software that will assist communities with the inventory and maintenance of urban forests.

PhillyTreeMap is the result of that development. Developed based on the open source code originating from the Urban Forest Map project in San Francisco, PhillyTreeMap enables members of the public to join government and non-profit organizations in adding and updating information about trees in the greater Philadelphia region. With an accurate and up to date tree inventory, we can work more efficiently toward maintaining our urban forest and promoting green communities in Philadelphia.

This material is based upon work supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under Agreement No. 2010-33610-20937 of the Small Business Innovation Research Grants Program. Any opinions, findings, and conclusions, or recommendations expressed in PhillyTreeMap.org are those of the partners or individuals and do not necessarily reflect the view of the U.S. Department of Agriculture.
