We can fill our map if it is too empty, or help the readers by adding more context. In this example, we replace our Landsat imagery by some thematics from the OpenStreetMap dataset. We will visualize land use types, rivers, and water bodies on our map. As we went through styling vector layers quite thoroughly before, we will only discuss the main guidelines to achieve nice results.

First of all, let's disable our Landsat layer, and enable the layers mentioned ...
