  "description": "<div style='text-align:Left;'><div><div><p><span>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.</span></p><p><span>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.</span></p><p><span>Extreme outliers were also modified, with any DBH larger than 80 inches being converted to a DBH of 80 inches.</span></p><p><span>The combined data set was processed using the USDA Forest Service i-Tree eco software, where structure and environmental benefits were estimated.</span></p></div></div></div>",
