USA Protected from Land Cover Conversion

Retirement Notice: This item is in mature support as of June 2024 and will be retired in December 2026. A new version of this item is available for your use. Esri recommends updating your maps and apps to use the new version. Areas protected from conversion include areas that are permanently protected and managed for biodiversity such as Wilderness Areas and National Parks. In addition to protected lands, portions of areas protected from conversion includes multiple-use lands that are subject to extractive uses such as mining, logging, and off-highway vehicle use. These areas are managed to maintain a mostly undeveloped landscape including many areas managed by the Bureau of Land Management and US Forest Service. The Protected Areas Database of the United States classifies lands into four GAP Status classes. This layer displays lands managed for biodiversity conservation (GAP Status 1 and 2) and multiple-use lands (GAP Status 3). Dataset Summary Phenomenon Mapped: Protected and multiple-use lands (GAP Status 1, 2, and 3) Units: Meters Cell Size: 30.92208102 meters Source Type: Thematic Pixel Type: 8-bit unsigned integer Data Coordinate System: WGS 1984 Mosaic Projection: Web Mercator Auxiliary Sphere Extent: 50 United States plus Puerto Rico, the US Virgin Islands, Guam, Northern Mariana Islands and American Samoa. Source: USGS National Gap Analysis Program PAD-US version 3.0 Publication Date: July 2022 ArcGIS Server URL: https://landscape10.arcgis.com/arcgis/ This layer displays protected areas from the Protected Areas Database of the United States version 3.0 created by the USGS National Gap Analysis Program. This layer displays areas managed for biodiversity where natural disturbances are allowed to proceed or are mimicked by management (GAP Status 1), areas managed for biodiversity where natural disturbance is suppressed (GAP Status 2), and multiple-use lands where extract activities are allowed (GAP Status 3). The source data for this layer are available here. A feature layer published from this dataset is also available. The polygon vector layer was converted to raster layers using the Polygon to Raster Tool using the National Elevation Dataset 1 arc second product as a snap raster. The service behind this layer was published with 8 functions allowing the user to select different views of the service. Other layers created from this service using functions include: USA Protected Areas USA Unprotected Areas USA Protected Areas - Gap Status 1-4 USA Protected Areas - Gap Status 1 USA Protected Areas - Gap Status 2 USA Protected Areas - Gap Status 3 USA Protected Areas - Gap Status 4 What can you do with this layer? This layer is suitable for both visualization and analysis across the ArcGIS system. This layer can be combined with your data and other layers from the ArcGIS Living Atlas of the World in ArcGIS Online and ArcGIS Pro to create powerful web maps that can be used alone or in a story map or other application. Because this layer is part of the ArcGIS Living Atlas of the World it is easy to add to your map: In ArcGIS Online, you can add this layer to a map by selecting Add then Browse Living Atlas Layers. A window will open. Type "Protected from Land Cover Conversion" in the search box and browse to the layer. Select the layer then click Add to Map. In ArcGIS Pro, open a map and select Add Data from the Map Tab. Select Data at the top of the drop down menu. The Add Data dialog box will open on the left side of the box, expand Portal if necessary, then select Living Atlas. Type "Protected from Land Cover Conversion" in the search box, browse to the layer then click OK. In ArcGIS Pro you can use the built-in raster functions to create custom extracts of the data. Imagery layers provide fast, powerful inputs to geoprocessing tools, models, or Python scripts in Pro.退役通知：本产品自2024年6月起进入成熟支持阶段，将于2026年12月正式退役。目前已有新版本可供使用，Esri建议您更新地图与应用程序以适配新版本。 免于转化保护的区域包括为生物多样性保护而永久保护与管理的区域，例如荒野保护区（Wilderness Areas）与国家公园（National Parks）。除保护地外，免于转化保护的区域还包含可开展采矿、伐木、非道路机动车使用等采掘利用活动的多用途土地。此类区域的管理目标是维持整体未开发的景观格局，其中多数由土地管理局（Bureau of Land Management）与美国林务局（US Forest Service）负责管理。 美国保护区数据库（Protected Areas Database of the United States）将土地划分为4类GAP状态（GAP Status）。本图层展示了用于生物多样性保护的土地（GAP状态1与2）以及多用途土地（GAP状态3）。 数据集摘要 制图现象：受保护及多用途土地（GAP状态1、2与3） 单位：米 像元大小：30.92208102米 源数据类型：专题数据 像素类型：8位无符号整数 数据坐标系：WGS 1984 拼接投影：Web Mercator 覆盖范围：美国50个州，以及波多黎各、美属维尔京群岛、关岛、北马里亚纳群岛和美属萨摩亚。 数据来源：美国地质调查局（USGS）国家差距分析计划（National Gap Analysis Program）美国保护区数据库（PAD-US）3.0版本 发布日期：2022年7月 ArcGIS服务器地址：https://landscape10.arcgis.com/arcgis/ 本图层展示了由美国地质调查局国家差距分析项目制作的美国保护区数据库3.0版本中的保护区范围。其涵盖三类区域：允许自然干扰自然发生或通过管理模拟自然干扰的生物多样性保护用地（GAP状态1）、抑制自然干扰的生物多样性保护用地（GAP状态2），以及允许采掘活动的多用途土地（GAP状态3）。本图层的源数据可在此处获取。基于此数据集发布的要素图层亦可供使用。 本多边形矢量图层通过多边形转栅格工具（Polygon to Raster Tool）转换为栅格图层，转换过程中以国家高程数据集（National Elevation Dataset）1弧秒产品作为对齐栅格。本图层对应的服务发布时搭载了8项功能，支持用户选择不同的服务视图。基于此服务通过功能生成的其他图层包括： 美国保护区 美国非保护区 美国保护区 - GAP状态1-4 美国保护区 - GAP状态1 美国保护区 - GAP状态2 美国保护区 - GAP状态3 美国保护区 - GAP状态4 本图层可用于ArcGIS生态系统中的可视化与分析工作。您可将其与自有数据及ArcGIS世界生活地图集（ArcGIS Living Atlas of the World）中的其他图层在ArcGIS Online与ArcGIS Pro中结合，制作可独立使用、或用于故事地图或其他应用程序的高性能Web地图。由于本图层属于ArcGIS世界生活地图集的一部分，添加至地图的操作十分简便： 在ArcGIS Online中，您可通过依次选择「添加」→「浏览生活地图集图层」将本图层添加至地图。此时将弹出窗口，在搜索框中输入“免于土地覆盖转化保护”即可找到目标图层，选中后点击「添加至地图」即可完成操作。 在ArcGIS Pro中，打开地图并选择「地图」选项卡中的「添加数据」，在下拉菜单顶部选择「数据」。此时左侧将弹出添加数据对话框，如有需要请展开「门户」选项并选择「生活地图集」。在搜索框中输入“免于土地覆盖转化保护”，找到目标图层后点击「确定」即可。在ArcGIS Pro中，您还可使用内置的栅格函数自定义提取该数据。影像图层可为Pro中的地理处理工具、模型或Python脚本提供高效、高性能的输入源。
