Timber Appraisal Zones (Feature Layer)

This dataset is a spatial display of US Forest Service stumpage market appraisal zones. A zone may encompass a Region, a National Forest, a group of Ranger Districts, or combinations thereof. Each unique market appraisal zone defines a localized stumpage market. In each market area, stumpage values reflect the market value of standing trees (on the stump) prior to felling, removal, and utilization in a value-added manufacturing activity. The zone boundary is typically determined by factors including, but not limited to, manufacturing facilities, hauling distances, species yield compositions, timber quality, market area competition, and logging methods. Timber Appraisal Zone MetadataThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

本数据集为美国森林服务机构林材市场评估区域的地理空间展示。一个区域可能包括一个区域、一个国家森林、一组巡林区，或其组合。每个独特的市场评估区域定义了一个本地化的林材市场。在每一个市场区域内，林材价值反映了立木（树桩上）在砍伐、移除及增值制造活动利用之前的市值。区域边界通常由包括但不限于制造设施、运输距离、树种产量组成、木材质量、市场区域竞争以及伐木方法等因素决定。林材评估区域元数据记录源自于为 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。
