With the knowledge that you've gained from the previous chapters, you can create various rich, web mapping applications for multiple devices. Now that you are aware of the most important aspects of OpenLayers 3, we will dig into some irregular topics that are not strongly related to the library. We will take a look at how we can implement QGIS and some third-party libraries in our workflow in order to make our lives easier or just extend the capabilities of our application.
In this chapter, we will cover the following topics:
As we are going to use QGIS in this chapter, you will need to have a working copy installed on your computer. Installing QGIS is straightforward; therefore, we will not discuss the process. For the best possible experience, update the software to its latest version before proceeding further. The example was created with QGIS 2.10 Pisa.
If you are using Windows or you need the source code, you can download both at http://qgis.org/en/site/forusers/download.html.
We will also use some third-party libraries, which are provided with the examples. You can find them in the js folder under the appropriate subdirectory. We will need Shapefile JS, Turf, JSTS, Cesium, and OL3-Cesium. The Cesium library is handled as part of the OL3-Cesium integration library; therefore, it is located in the latter's folder. For this chapter, we will use ch03_layerorder for the base of our code, just like we did in the previous one.
