Chapter 3. Working with Layers

Now that we have learned the basics of creating a frame for our custom WebGIS client, we will proceed to build a fully operational layer tree. Through out the chapter, we will revise how to manage the layer stack of OpenLayers 3 and utilize these capabilities in our application.

In this chapter, we will cover the following topics:

  • Adding and removing layers dynamically

  • Adding layers with the HTML5 File API

  • Changing layer attributes based on user input

  • Changing the order of a layer with the HTML5 Drag and Drop API
