Tree Inventory on Main Campus 2019

1. Title & Overview Dataset Name: Tree Inventory on Main Campus 2019 Summary: Spatial dataset of Trees on Temple University Main Campus, including environmental characteristics. Geographic Coverage: Temple University Main Campus, Philadelphia, PA Time Period: Created July 1st 2019; last updated Feb. 2020. 2. Purpose & Use Intended Use: To visualize Tree inventory and their benefits on Temple University Main Campus in 2019 for mapping, analysis, and operational reference. Limitations: No documented constraints, scale issues, or known data caveats; users should verify suitability for high‑precision applications. Update Frequency: Updated on an as‑needed basis. 3. Data Source & Methodology Source(s): Temple University Office of Sustainability Collection Method: Not formally documented. Processing Steps: Key transformations, cleaning steps, and calculations are not fully documented. 4. Variable Breakdown (Attribute Table Fields) - FID (Object ID): Object ID. Example: N/A - Id (Long): Id. Example: N/A - Common_Nam (Text): Common name of species. Example: "Basswood" - Genus (Text): Genus. Example: "Malus" - Species (Text): Tree Species. Example: "Styraciflua" - Health (Text): Health index. Example: "Good" - Crown_Radi (Double): Canopy Spread. Example: "32" - Tree_ID (Double): Tree Id. Example: N/A - Native_Sta (Text): Native Status. Example: "Native Species" - Date (Text): Date tree was assessed. Example: "May-June 2019" - Notes (Text): Notes. Example: N/A - Latin Name (Text): Latin Name. Example: "Liquidambar Styraciflua" - CBH (Double): Tree crown base height. Example: "12" - Alt Species (Text): Possible alternative species. Example: "Pendula" - Family (Text): Tree family group. Example: "Hamamelidaceae" - Street Tree (Text): Street Tree (Yes/No). Example: "Yes" - DBH (Double): Diameter at Breast Height. Example: "21.00847" - x (Long): x-coordinate. Example: N/A - y (Long): y-coordinate. Example: N/A - Shape (Geometry): Spatial feature representing trees. Example: “Point” 5. Data Quality & Accuracy Positional Accuracy: Approximately 5–10 meters from the true on‑ground location; not survey‑grade. Attribute Accuracy: High; believed to accurately reflect tree inventory at time of creation. Completeness: Some missing or null values in every field except (Common_Nam) 6.
