Site Amenities Lines Cape Cod 2025

Overview This feature service provides detailed line features representing various site amenities located in the Cape Cod region. The dataset was developed from high-resolution aerial imagery captured in Spring 2025, ensuring precise geospatial accuracy suitable for planimetric mapping at a 1:40 scale. Feature Layer Site Amenity Lines: This layer contains line features of physical site amenities including fences, walls, hedges, guard rails, gates, decks, patios, pools, and other similar structures commonly found along roadsides or within campus-like environments. Data Sources and Quality The information is derived from four-band (true color and near-infrared) aerial imagery collected under ideal spring conditions to minimize foliage and environmental obstructions. The imagery acquisition focused on leaf-off, snow-free periods with clear skies and minimal shadows, achieving a ground sample resolution of 7.5 cm. The horizontal positional accuracy meets stringent mapping standards, with a maximum error threshold of 0.38 meters at 95% confidence. Geographic Coverage The dataset covers the Cape Cod area, reflecting features within this unique coastal Massachusetts region, suitable for local planning, environmental management, and infrastructural assessments. Applications Infrastructure and landscape asset inventory and monitoring Urban planning and campus development Maintenance and condition assessment of site amenities Integration into broader GIS projects requiring detailed site infrastructure data概览 本要素服务提供代表科德角（Cape Cod）区域内各类场地附属设施的详细线状要素。本数据集基于2025年春季拍摄的高分辨率航空影像制作，可保证精准的地理空间精度，适用于1:40比例尺的平面测图工作。 要素图层 场地附属设施线状要素图层：该图层包含各类实体场地附属设施的线状要素，涵盖围栏、墙体、树篱、护栏、大门、露台、庭院、泳池以及其他常见于路边或类校园环境中的同类设施。 数据来源与质量 本数据集信息源自四波段（真彩色与近红外）航空影像，采集于理想春季条件下，以最大限度减少植被与环境遮挡。影像采集选择了落叶、无雪、天空晴朗且阴影最少的时段，地面采样分辨率达到7.5厘米。其水平位置精度符合严格的测绘标准，在95%置信度下的最大误差阈值为0.38米。 地理覆盖范围 本数据集覆盖科德角区域，收录了马萨诸塞州这片独特沿海区域内的相关要素，可用于地方规划、环境管理与基础设施评估等工作。 应用场景 基础设施与景观资产的盘点与监测；城市规划与校园建设；场地附属设施的维护与状况评估；可集成至需要详细场地基础设施数据的各类通用地理信息系统（GIS）项目中。
