This layer displays coal fields of the Conterminous United States from the U.S. Coal Resources and Reserves Assessment Project by the U.S. Geological Survey (USGS) Energy Resources Program. Dataset Summary Phenomenon Mapped: Coal Fields of the United States Coordinate System: Web Mercator Auxiliary Sphere Extent: 48 Conterminous United States Visible Scale: All Scales Source: National Coal Resource Assessment Publication Date: 2013 East, J.A., 2013, Coal fields of the conterminous United States—National Coal Resource Assessment updated version: U.S. Geological Survey Open-File Report 2012–1205, one sheet, scale 1:5,000,000, available at https://pubs.usgs.gov/of/2012/1205/. What can you do with this layer? This layer can be used throughout the ArcGIS system. Feature layers can be used just like any other vector layer. You can use feature layers as an input to geoprocessing tools in ArcGIS Pro or in Analysis in ArcGIS Online. Combine the layer with others in a map and set custom symbology or create a pop-up tailored for your users. For the details of working with feature layers the help documentation for ArcGIS Pro or the help documentation for ArcGIS Online are great places to start. The ArcGIS Blog is a great source of ideas for things you can do with feature layers. This layer is part of ArcGIS Living Atlas of the World that provides an easy way to find and explore many other beautiful and authoritative layers, maps, and applications on hundreds of topics.本图层展示由美国地质调查局（U.S. Geological Survey, USGS）能源资源项目实施的《美国煤炭资源与储量评估计划》中的美国本土48州（Conterminous United States）煤炭田分布数据。 数据集摘要 测绘对象：美国煤炭田 坐标系：Web墨卡托辅助球面（Web Mercator Auxiliary Sphere） 覆盖范围：美国本土48州 可视比例尺：全比例尺 数据来源：全国煤炭资源评估 发布日期：2013年 作者East, J.A.于2013年发布的《美国本土煤炭田——全国煤炭资源评估更新版》对应美国地质调查局公开文件报告2012–1205号，为单幅图件，比例尺1:5,000,000，可通过https://pubs.usgs.gov/of/2012/1205/ 获取。 本图层可应用于以下场景： 本图层可适配全系列ArcGIS系统。要素图层（Feature layer）的使用方式与其他矢量图层并无二致，可作为ArcGIS Pro或ArcGIS Online中地理处理工具的输入数据源；可将该图层与地图内其他图层进行叠加组合，自定义符号系统，或为目标用户定制专属弹窗信息。如需了解要素图层的具体操作方法，可参考ArcGIS Pro帮助文档或ArcGIS Online帮助文档作为入门指引。ArcGIS博客（ArcGIS Blog）也是获取要素图层应用创意的优质资源平台。 本图层隶属于ArcGIS世界生活地图集（ArcGIS Living Atlas of the World），该图集可为用户提供便捷的查找与探索渠道，助力其获取数百个主题下的大量优质权威图层、地图及应用程序。
