Summary

Congratulations! You are almost there! In this chapter, you learned a bit about extendibility and modularity. You learned about the perks of modular applications and how to bring third-party libraries into your workflow. You also learned a few things about QGIS, including not only creating a quick preview of your project but also salvaging valuable information from it. You explored the usage of some of the most useful third-party libraries for a WebGIS application built in OpenLayers 3. To top this, we managed to create beautiful 3D visualizations with Cesium and OpenLayers 3, which was the most exciting part of this chapter.

In the final chapter, you will learn how to use the Closure Compiler and create custom builds of OpenLayers 3. This is useful to create lightweight versions when we do not need the full capability of this robust library. Additionally, you will learn how to extend the source code or expose originally hidden functions, which we would like to access for our project...
