2018 data: This dataset was developed as part of an Urban Tree Canopy (UTC) assessment for Philadelphia,Pennsylvania. It shows how tree canopy changed during the period 2008-2018, highlighting trees that were gained or lost during the 10-year period. It is intended for use in monitoring patterns of change in Philadelphia,Pennsylvania tree canopy. 2015 data: Collection of tree canopy outlines and points generated by Intergraph Government Solutions (IGS) for trees >6' diameter. Update generated off the 2015 Leaf-Off 3" AccuPLUS Imagery representing changes in tree canopy visible within the imagery. Heights have been derived separately for each tree canopy outline from 2015 LiDAR data capture.

The Philadelphia Land Cover Raster provides data on the types of surfaces in Philadelphia in 2008 as well as an update in 2018. The data identifies seven categories: tree canopy, grass/shrub, bare earth, water, buildings, roads, other paved surfaces. The data primarily was intended to demonstrate tree canopy levels in Philadelphia. When tree canopy covers another surface type, that area is placed in the tree canopy category. The data was gathered with the assistance of the University of Vermont Spatial Analysis Laboratory.

Last updated 3/9/2016. In 2006, a complete inventory of all the City’s street trees, including trees located within sidewalks, between sidewalks and curbs, or within 6 feet of the street if no sidewalk existed was conducted. One hundred volunteers were trained to record address, location, tree species, tree diameter, condition, and other related information. Trees located in parks and other public property were not included. Approximately 25,000 street trees were counted and the data was loaded into a tree database that the Forestry Division uses daily to manage the trees, track tree work, and record constituent concerns.

Citywide street tree data from the 2005 Street Tree Census, conducted partly by volunteers organized by NYC Parks & Recreation. Trees were inventoried by address, and were collected from 2005-2006. Data collected includes tree species, diameter, condition.

This EnviroAtlas dataset addresses the tree buffer along heavily traveled roads. The roads are interstates, arterials, and collectors within the EnviroAtlas community boundary. In this community, tree cover is defined as Trees & Forest, Orchards, and Woody Wetlands. Sufficient tree bufferage is defined as 25% coverage within the circular moving window with a radius of 14.5m at any given point along the roadway. There are potential negative health effects for those living in a location without a sufficient tree buffer. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
