City of Washington, DCDC 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. The combined data set was processed using the USDA Forest Service i-Tree eco software, where structure and environmental benefits were estimated.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/08bda06465a74cd59a6d4231d882588d_11engOpen Data DCPublicDC Trees [District of Columbia--Washington]Web servicesDistrict of Columbia--WashingtonDistrict of ColumbiaLast Modified: 2024-03-27
