Street Pavement 2025

Overview This feature service provides detailed polygon data representing paved or impervious surfaces, specifically street pavement, within the Cape Cod region. The data was developed as a part of a project funded by the Cape Cod Commission and completed by NV5, using high-resolution aerial imagery acquired in Spring 2025. Feature Layers Street Pavement: This polygon layer represents various types of pavement surfaces including concrete, asphalt, chip and seal, brickpaver, cobblestone, gravel, and other types. It captures different uses of these surfaces such as streets, sidewalks, bike paths, parking lots, and curbs among others. The data quality is high, with a horizontal positional accuracy within 0.38 meters at a 95% confidence level, suitable for detailed planimetric mapping at 1:4000 scale. Imagery used for data capture consists of 4-band true color and near infrared with very specific acquisition conditions ensuring minimal shadows and clear visibility of surfaces during the leaf-off period in early 2025. Geographic Coverage The data covers the Cape Cod area with precise mapping of urban and transportation infrastructure pavement surfaces, reflecting current conditions as of spring 2025. Use Cases Urban planning and infrastructure management addressing pavement maintenance and replacement prioritization. Transportation network analysis that includes multi-modal paths such as pedestrian sidewalks and bike routes. Environmental and impervious surface studies requiring accurate pavement delineations. Public works and asset management for access control purposes. Supporting GIS applications that require up-to-date and accurate pavement surface data for the Cape Cod region.概述 本要素服务提供科德角（Cape Cod）区域内铺装或不透水地表（特指道路路面）的详细多边形数据。该数据集由科德角委员会（Cape Cod Commission）资助的项目开发，由NV5公司完成，制作时采用了2025年春季获取的高分辨率航空影像。 要素图层 道路路面：该多边形图层涵盖多种类型的铺装表面，包括混凝土、沥青、碎石封层、砖铺面、鹅卵石、碎石及其他类别。其覆盖此类铺装表面的各类应用场景，涵盖道路、人行道、自行车道、停车场及路缘石等。该数据集数据质量优异，在95%置信度下水平位置精度可达0.38米，适用于1:4000比例尺的详细平面制图。数据采集所用影像为4波段真彩色与近红外影像，采集条件严苛，确保2025年初落叶期内阴影最少、地表辨识度清晰。 地理覆盖范围 本数据集覆盖科德角区域，精准绘制了城市与交通基础设施的路面地表，反映2025年春季的当前地表实况。 应用场景 可用于城市规划与基础设施管理，开展路面养护与更换优先级规划；可用于包含步行人行道、自行车道等多模态路径的交通网络分析；可用于需要精准路面轮廓的环境与不透水地表研究；可用于公共工程与资产管理的通行控制场景；亦可支撑针对科德角区域、需使用最新精准路面数据的各类地理信息系统（GIS）应用。
