In this chapter, we took a look at some of the different ways in which we can take control of GeoServer. From advanced uses of SLD styles to manipulating the response from a WMS GetFeatureInfo request, we saw how powerful and flexible GeoServer can be.

We saw how we can benefit from the presence of the WPS extension when it comes to creating SLD styles to render maps. By making use of the render transformations that the WPS extension provides, we saw how easy it is to create a style that can dynamically generate a response based on our source data. To illustrate this, we saw how we can create a style that can generate heatmaps from any point dataset.

After looking at an advanced SLD, we learned about an alternative means of creating styles for our maps. We learned that the CSS style extension allows us to take a common web standard, Cascading Style Sheets, and use it to describe styling rules for our maps.
