Visitor Map Symbology - Motor Vehicle Use Map Roads

The feature class indicates the specific types of motorized vehicles allowed on the designated routes and their seasons of use. The feature class is designed to be consistent with the MVUM (Motor Vehicle Use Map). It is compiled from the GIS Data Dictionary data and NRM Infra tabular data that the administrative units have prepared for the creation of their MVUMs. Only roads with a SYMBOL attribute value of 1, 2, 3, 4, 11, and 12 are Forest Service System roads and contain data concerning their availability for OHV (Off Highway Vehicle) use. This data is published and refreshed on a unit by unit basis as needed. Data for each individual unit must be verified and proved consistent with the published MVUMs prior to publication.The Forest Service's Natural Resource Manager (NRM) Infrastructure (Infra) is the agency standard for managing and reporting information about inventory of constructed features and land units as well as the permits sold to the general public and to partners.

该特征类标示了指定路线上允许通行的特定类型机动车辆及其使用季节。该特征类旨在与机动车辆使用地图（MVUM）保持一致性。它由GIS数据字典数据和行政单位为编制其MVUMs而准备的NRM基础设施表格数据汇编而成。仅当道路具有1、2、3、4、11和12的SYMBOL属性值时，才属于森林服务机构道路，并包含有关其越野车（OHV）使用可用性的数据。该数据根据需要按单位进行发布和更新。在发布之前，每个单独单位的数据必须经过验证，并确保与已发布的MVUMs保持一致。美国森林服务局的自然资源管理者（NRM）基础设施（Infra）是该机构用于管理和报告有关构造特征和土地单位库存以及向公众和合作伙伴销售的许可证信息的标准。欲获取完整的元数据描述，请访问此URL：http://data.fs.usda.gov/geodata/edw/edw_resources/meta/S_USA.Road_MVUM.xml本记录源自向https://data.gov目录提供数据的美国农业部企业数据目录。本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。欲获取完整信息，请访问https://data.gov。
