Summary
In this final chapter we gave a brief description of WFS and WCS—two different ways to serve spatial data on the Web. But there's much more than this in the GeoServer project.
We can just mention the main features we didn't cover in the book, such as Web Processing Service (WPS), which is a standard protocol for invoking the geospatial processing services, CSS styling, which is an alternative way of simplifying SLD complexity to style your layers, and time support for vector and raster data.
Whatever your needs in serving spatial data, GeoServer has an answer, or will have it soon!
