Terrain - Elevation Tinted Hillshade

This map provides an elevation tinted hillshade surface generated dynamically using a chain of server-side functions on a Terrain layer. A tinted hillshade is a combination of a hillshade applied to the Terrain, fused to a colormap applied to the same Terrain to represent elevation. The hillshading is based on a solar altitude angle of 45 degrees, and solar aspect angle of 315 degrees. The z factor is varied based on scale so that a suitable hillshade is visible at all scales. Update Frequency: Quarterly Coverage: World/Global Data Sources: This layer is compiled from a variety of best available sources from several data providers. To see the coverage and extents of various datasets comprising this service in an interactive map, see World Elevation Coverage Map. What can you do with this layer? Use for Visualization: Yes. This is appropriate for visualizing the shape and height of the terrain at a range of map scales. The image service can be added to applications or maps to enhance a users’ contextual understanding. Use for Analysis: No. To learn more about the technique used in this map to fuse the elevation tint with hillshade, refer NAGI fusion method paper and blog. For more details such as Data Sources, Mosaic method used in this layer, please see the Terrain layer. This layer allows query, identify, and export image requests. The layer is restricted to a 5,000 x 5,000 pixel limit in a single export image request. This layer is part of a larger collection of elevation layers that you can use to perform a variety of mapping and analysis tasks.

本地图提供基于地形图层（Terrain layer）通过一系列服务端函数动态生成的高程着色晕渲表面。着色晕渲是将应用于地形图层的晕渲效果，与应用于同一地形图层以表征高程的色彩映射表（colormap）相融合的产物。该晕渲基于45度的太阳高度角与315度的太阳方位角，Z因子会根据比例尺动态调整，以确保在所有比例尺下均能呈现清晰合适的晕渲效果。
