World Elevation GMTED

The Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) dataset provides a 7.5 arcsecond (approximately 250 meter resolution) digital elevation model with world-wide coverage at a resolution suitable for regional to continental scale analyses. This layer provides access to a 250m cell-sized raster created from the Global Multi-resolution Terrain Elevation Data 2010 7.5 arcsecond mean elevation product. The dataset represents a compilation and synthesis of 11 different existing raster data sources. The data were published in 2011 by the USGS and the National Geospatial-Intelligence Agency. The dataset is documented in the publication: Danielson and Gesch. 2011. Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010). U.S. Geological Survey Open-File Report 2011–1073, 26 p. Dataset Summary Analysis: Restricted single source analysis. Maximum size of analysis is 16,000 x 16,000 pixels. What can you do with this layer? This layer is suitable for both visualization and analysis. It can be used in ArcGIS Online in web maps and applications and can be used in ArcGIS Desktop. Restricted single source analysis means this layer has size constraints for analysis and it is not recommended for use with other layers in multisource analysis. This layer has query, identify, and export image services available. This layer is restricted to a maximum area of 16,000 x 16,000 pixels - an area 4,000 kilometers on a side or an area approximately the size of Europe. The Living Atlas of the World provides an easy way to explore the landscape layers and many other beautiful and authoritative maps on hundreds of topics.2010年全球多分辨率地形高程数据（Global Multi-resolution Terrain Elevation Data 2010，GMTED2010）数据集提供了7.5角秒（约250米分辨率）的数字高程模型，覆盖全球，其分辨率适配区域级至大陆级的分析需求。本图层可获取基于该数据集7.5角秒平均高程产品生成的250米像元尺寸栅格数据。 该数据集整合并合成了11种现有栅格数据源，由美国地质调查局（USGS）与国家地理空间情报局（National Geospatial-Intelligence Agency）于2011年发布。其相关文档记载于以下出版物：Danielson与Gesch，2011年。《2010年全球多分辨率地形高程数据（GMTED2010）》，美国地质调查局公开文件报告2011–1073，共26页。 数据集摘要分析规则为：受限单源分析，单次分析的最大像素尺寸为16000×16000。 本图层可应用场景如下：本图层适配可视化与分析两类场景，可用于ArcGIS Online的网页地图与应用程序，同时也支持在ArcGIS Desktop中使用。受限单源分析意味着本图层存在分析尺寸限制，不建议与其他图层进行多源联合分析。本图层支持查询、识别与影像导出服务。本图层的最大分析区域限制为16000×16000像素，对应边长4000公里的区域，面积大致与欧洲相当。 全球动态地图集（The Living Atlas of the World）为用户提供了便捷途径，可探索地形图层以及数百个主题下的众多精美权威地图。
