Sites of marinas, yacht clubs, and boat yards along the Massachusetts coast, 2007

These GIS data show the locations of marinas, boatyards, yacht clubs, and yachting related facilities along the Massachusetts coast. The data were compiled from public lists, databases, and visual inspection of orthoimagery. While not fully comprehensive, these data constitute a majority of the marina-type resources available to recreational yachtspersons. All data are represented as points with associated attribute data. Marinas are generally defined by CZM for these data as faculties that cater to recreational yachtspersons and provide berths, moorings, maintenance and repair, hauling, storage, chandely, fuel, and/or other supplies. Marina types were subdivided into marinas, yacht clubs, boat yards, municipal facilities, and unknown. All "marinas" have tidal frontage.

本地理信息系统（GIS, Geographic Information System）数据集展示了马萨诸塞州沿岸的游艇码头、修船场、游艇俱乐部及游艇相关设施的点位分布。本数据集通过公开名录、数据库及正射影像目视解译进行整合编制。尽管该数据集并非完全全覆盖，但已涵盖休闲游艇使用者可获取的绝大多数游艇类资源。所有数据均以带有关联属性数据的点位形式进行表达。针对本数据集，海岸带管理（CZM, Coastal Zone Management）将游艇码头一般定义为面向休闲游艇使用者，提供泊位、系泊设施、维护维修、起吊作业、存储服务、船舶用品供应、燃油及/或其他补给的场所。游艇码头类型被划分为游艇码头、游艇俱乐部、修船场、市政设施及未知类型五类。所有标注为"游艇码头"的点位均临潮汐岸线。
