MVUM Symbology - Motor Vehicle Use Map Roads (Labels)

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 Motor Vehicle Use Map (MVUM). 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. Information for each individual unit must be verified as to be consistent with the published MVUMs prior to inclusion in this data. Not every National Forest has data included in this feature class.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog. Data for this record includes the following resources: ISO-19139 metadata ArcGIS Hub Dataset ArcGIS GeoService OGC WMS CSV Shapefile GeoJSON KML For complete information, please visit https://data.gov.

该属性类别旨在标识指定路线上允许通行的各类机动车辆及其使用季节。该属性类别的设计旨在与《机动车使用图》（Motor Vehicle Use Map，简称MVUM）保持一致。仅当道路的SYMBOL属性值为1、2、3、4、11和12时，才属于森林服务机构道路，并包含有关其是否可供越野车（Off Highway Vehicle，简称OHV）使用的相关数据。此数据根据需要按单位逐一发布和更新。在将每个单独单位的信息纳入本数据之前，必须核实其与已发布的MVUMs的一致性。并非每个国家森林都包含在此属性类别中的数据。本记录摘自美国农业部企业数据清单，该清单是https://data.gov目录的来源。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。如需完整信息，请访问https://data.gov。
