Chapter 1. Creating Simple Maps with OpenLayers 3

OpenLayers 3 is the most robust open source web mapping library out there, highly capable of handling the client side of a WebGIS environment. Whether you know how to use OpenLayers 3 or you are new to it, this chapter will help you to create a simple map and either refresh some concepts or get introduced to them. As this is a mastering book, we will mainly discuss the library's structure and capabilities in depth. In this chapter we will create a simple map with the library, and revise the basic terms related to it.

In this chapter we will cover the following topics:

  • Structure of OpenLayers 3
  • Architectural considerations
  • Creating a simple map
  • Using the API documentation effectively
  • Debugging the code

Before getting started

Take a look at the code provided with the book. You should see a js folder in which the required libraries are stored. For the first few chapters, ol.js, and ol.css in the ol3-3.11.0 folder will be sufficient. The code is also available on GitHub. You can download a copy from the following URL: https://github.com/GaborFarkas/mastering_openlayers3/releases. Take a look at the following screenshot:

Before getting started

Note

You can download the latest release of OpenLayers 3 from its GitHub repository at https://github.com/openlayers/ol3/releases. For now, grabbing the distribution version (v3.11.0-dist.zip) should be enough.

Creating a working environment

There is a security restriction in front end development, called Cross Origin Resource Sharing (CORS). By default, this restriction prevents the application from grabbing content from a different domain. On top of that, some browsers disallow reaching content from the hard drive when a web page is opened from the file system. To prevent this behavior, please make sure you possess one of the following:

  • A running web server (highly recommended)
  • Firefox web browser with security.fileuri.strict_origin_policy set to false (you can reach flags in Firefox by opening about:config from the address bar)
  • Google Chrome web browser started with the --disable-web-security parameter (make sure you have closed every other instance of Chrome before disabling security)
  • Safari web browser with Disable Local File Restrictions (in the Develop menu, which can be enabled in the Advanced tab of Preferences)

Tip

You can easily create a web server if you have Python 2 with SimpleHTTPServer, or if you have Python 3 with http.server. For basic tutorials, you can consult the appropriate Python documentation pages.
