National Forest System Trails (Feature Layer)

The Trails Layer is designed to provide information about National Forest System trail locations and characteristics to the public. When fully realized, it will describe trail locations, basic characteristics of the trail, and where and when various trail uses are prohibited, allowed and encouraged. Because the data readiness varies between Forests, each Forest will approve which level of attribute subset are published for that forest. Forests can provide no information or one of three attribute subsets describing trails. The attribute subsets include TrailNFS_Centerline which includes the location and trail name and number; TrailNFS_Basic which adds information about basic trail characteristics; and TrailNFS_Mgmt which adds information about where and when users are prohibited, allowed, and encouraged. When a Forest chooses to provide the highest attribute subset, TrailNFS_Mgmt, these attributes must be consistent with the Forest's published Motorized Vehicle Use Map (MVUM). Metadata for the individual Forest feature classes used to compile this feature class are available at data.fs.usda.gov/geodata/edw/dir_trails.php. MetadataThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

《路径层》旨在向公众提供关于国家森林系统路径位置及其特性的信息。当完全实现时，它将描述路径位置、路径的基本特性以及各种路径使用何时何地被禁止、允许和鼓励。由于各森林的数据准备程度不同，每个森林将批准发布该森林的哪些属性子集级别。森林可以不提供信息或提供描述路径的三个属性子集之一。属性子集包括包含位置和路径名称及编号的《路径NFS中心线》；增加基本路径特性的《路径NFS基础》；以及增加用户何时何地被禁止、允许和鼓励的《路径NFS管理》。当森林选择提供最高属性子集《路径NFS管理》时，这些属性必须与森林发布的《机动车辆使用地图》（MVUM）保持一致。用于编制此特征类的单个森林要素类元数据可在data.fs.usda.gov/geodata/edw/dir_trails.php获取。元数据记录源自美国农业部企业数据目录，该目录输入至https://data.gov目录。此记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService、OGC WMS、CSV、Shapefile、GeoJSON以及https://apps.fs.usda.gov/arcx/rest/services/EDW/EDW_TrailNFSPublish_01/MapServer/0。如需完整信息，请访问https://data.gov。
