Africa Terrestrial Ecosystems

Retirement Notice: This item is in mature support as of August 2025 and will be retired in December 2026. Please use this source dataset and follow the steps in the From Vector to Raster blog as a replacement for this service. Esri recommends updating your maps and apps. Organisms and nonliving elements of the environment such as climate, soil, and water are connected through the movement of nutrients and energy in ecosystems. Ecosystems represent specific areas where organisms and environmental conditions create a network of interactions and are affected by forces such as disturbance and succession. This layer provides access to a 100m cell sized raster of Ecosystems of Africa. The layer’s attributes include macrogroup, division, formation, subclass, and class. The layer was derived from data described in the publication A New Map of Standardized Terrestrial Ecosystems of Africa. The data covers the continent of Africa, Madagascar, and other nearby islands. The data were produced in 2013. Dataset Summary Analysis: Restricted single source analysis. Maximum size of analysis is 24,000 x 24,000 pixels. What can you do with this layer? This layer has query, identify, and export image services available. The layer is restricted to a 24,000 x 24,000 pixel limit for these services, which represents an area roughly 2,400 kilometers on a side. 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.停用通知：本服务自2025年8月起进入成熟支持阶段，并将于2026年12月正式停用。请使用本源数据集，并遵循《从矢量到栅格（From Vector to Raster）》博客中的操作步骤作为本服务的替代方案。Esri建议您更新相关地图与应用程序。 生态系统中，生物与气候、土壤、水体等非生物环境要素通过营养物质与能量的流动实现相互联结。生态系统是指在特定区域内，生物与环境条件形成相互作用网络，并受干扰、演替等外力影响的区域。 本图层（layer）提供像元尺寸为100米的非洲陆地生态系统栅格（raster）数据访问服务。该图层的属性字段包含大类群（macrogroup）、分区（division）、群系（formation）、亚类（subclass）与类（class）。 本图层的数据源自发表于《非洲标准化陆地生态系统新图谱（A New Map of Standardized Terrestrial Ecosystems of Africa）》的研究数据集。数据覆盖非洲大陆、马达加斯加岛及周边其他岛屿，该数据集制作于2013年。 数据集摘要分析说明：仅支持单源分析，单次分析的最大像素尺寸限制为24000×24000。 您可通过本图层实现以下功能：本图层支持查询、识别与影像导出服务。上述服务的像素尺寸限制为24000×24000，对应边长约2400公里的区域。仅支持单源分析意味着本图层存在分析尺寸约束，不建议与其他图层进行多源联合分析。
