Mapbox Cookbook

Overview of this book

Maps are an essential element in today’s location aware applications. Right from displaying earth surface information to creating thematic maps displaying plethora of information, most of the developers lack the necessary knowledge to create customizable maps with combination of various tools and libraries. The MapBox platform is one such platform which offers all the tools and API required to create and publish a totally customizable map. Starting with building your first map with the online MapBox Editor, we will take you all the way to building advanced web and mobile applications with totally customizable map styles. Through the course of chapters we’ll learn CartoCSS styling language and understand the various components of MapBox platform and their corresponding JavaScript API. In the initial few chapters we will dive deeper into the TileMill and MapBox Studio components of MapBox and use them to generate custom styled map tiles and vector maps. Furthermore, we will publish these custom maps using PHP, node.js and third party tools like Geoserver. We’ll also learn to create different visualizations and map styles like a choropleth map, a heat map and add user interactivity using a UFTGrid. Moving on, we dive into advanced concepts and focus on integration with third party services like Foursquare, Google FusionTables, CartoDB, and Torque to help you populate and even animate your maps. In the final chapter we’ll learn to use the Mapbox SDK to create and publish interactive maps for the iOS platform. By the end of this book, you will learn about MapBox GL and how to create a fully functional, location-aware mobile app, using the maps styles created in the recipes.

Getting mouse coordinates


One of the most important aspects of using maps is user interaction. Interacting with the map can be done in various ways, which also depends on the device used; for example, you can hover over a location using the mouse, but you can't do this using a touch-based device, such as a smartphone. In smartphones, you can use multitap or perform gestures, and these user interactions cannot be performed using the mouse.

In this recipe, you will learn how to use event listeners to trigger actions in order to implement user interaction in your map.

How to do it…

The condensed steps to be performed are as follows:

  1. Create a map with baseLayer.

  2. Then create an event listener using map.on('mousemove', mouseMovedCallback).

  3. In the callback method, get the latitude and longitude.

  4. Now, construct an HTML file that shows the latitude and longitude and inject the HTML file into a div to display the mouse coordinates.

Let's perform these steps now:

  1. Start by opening the starter project directory...
