    DC Estimated Trees

    Metadata Updated: February 5, 2025

    Dataset estimates location and size of trees in the District of Columbia that are not managed by the Urban Forestry Division (https://opendata.dc.gov/datasets/urban-forestry-street-trees/explore). Trees are modeled using an automated feature extraction process applied to 2022 LiDAR data. All data is an estimate, and intended for general representation purposes.

    DC 2022 LiDAR was used and processed using the “Extract Trees using Cluster Analysis” script which is included as part of Esri’s 3D Basemap solution. All LiDAR-derived trees within 2 meters of a Urban Forestry Division tree were removed as being duplicates.

    Tree diameter (DBH, in inches) was estimated for the LiDAR-derived trees from calculated tree height (in feet) based on the equation: DBH = 0.4003*height - 1.9557. This equation was derived from a statistical analysis of a detailed park inventory tree data set and has an R^2 = 0.7418.

    Extreme outliers were also modified, with any DBH larger than 80 inches being converted to a DBH of 80 inches.
