Data federation addresses the problem of integrating data from heterogeneous source models and includes concepts to map those different source models into the common model at the federated layer.

数据联合处理有关集成来自异类源模型的数据的问题，包括将这些不同的源模型映射到联合层的公共模型的概念。

The Gradient Map should be the topmost layer first and the Hue/Saturation below it in the Layers Panel.

在图层面板中，渐变映射层应该是顶部图层，色相/饱和度图层在它的下面。

To create a nice, functional map, you might just turn on the "roads" layer.

想要建立简洁实用的地图，你只需要打开道路图层即可。

So, this approach requires one more layer of effort: converting the height map (or at least its visible tiles) into a "normal map" which is smooth and natural enough to be subjected to lighting effects and then displayed on screen.
