A text layer is stored as a separate SDF data store, independent from the current map. You can use it in the current map, but you can also reuse it in other maps. To do so, attach it as you would any other SDF file.
Another advantage of text layers is that you can position the text on the layer, as you would an object on a drawing layer. You can style and rotate text on a text layer as well.
In this lesson, you create and style a text layer and specify its contents. Then you will save it out to a separate data store for use in other maps.
