Street Trees 2025

Overview This feature service provides detailed spatial information on street trees located near streets within the Cape Cod region. The data were collected and updated based on high-resolution aerial imagery acquired in Spring 2025, ensuring high positional accuracy suitable for planimetric mapping at a 1:40 scale. Feature Layers StreetTrees: This layer contains point locations of selected street trees with height attributes. Geographic Coverage The data covers the Cape Cod region as part of a project funded by the Cape Cod Commission and executed by Quantum Spatial, Inc. The imagery and resulting data reflect conditions present during the Spring 2025 growing season. Data Quality and Acquisition The collection employed four-band imagery (true color and near-infrared) taken under optimal conditions (leaf-off, snow-free, minimal shadows) with a ground sample distance of 7.5 cm. Horizontal positional accuracy adheres to a strict 0.38-meter NSSDA standard (95% confidence). Use Cases Urban forestry planning and management Environmental and ecological studies Infrastructure planning considering tree conditions and wires presence Public works and utility coordination概述 本要素服务提供科德角（Cape Cod）区域沿街分布的行道树详细空间信息。本数据集基于2025年春季获取的高分辨率航空影像进行采集与更新，可保证较高的位置精度，适用于1:40比例尺的平面制图。 要素图层 行道树图层（StreetTrees）：该图层包含已筛选行道树的点位坐标及其高度属性信息。 地理覆盖范围 本数据集覆盖科德角（Cape Cod）区域，相关项目由科德角委员会（Cape Cod Commission）资助、量子空间公司（Quantum Spatial, Inc.）负责执行。影像及最终生成的数据反映了2025年春季生长季的实际状况。 数据质量与采集方式 本次采集采用四波段影像（真彩色与近红外波段），采集条件为最优状态：无叶片、无积雪、阴影最少，地面采样距离为7.5厘米。水平位置精度严格遵循0.38米的国家空间数据精度标准（NSSDA）（95%置信度）。 应用场景 城市林业规划与管理、环境与生态研究、结合树木状况与线缆分布的基础设施规划、公共工程与公用事业协调
