Google Maps JavaScript API Cookbook

Overview of this book

Day by day, the use of location data is becoming more and more popular, and Google is one of the main game changers in this area. The Google Maps JavaScript API is one of the most functional and robust mapping APIs used among Geo developers. With Google Maps, you can build location-based apps, maps for mobile apps, visualize geospatial data, and customize your own maps.Google Maps JavaScript API Cookbook is a practical, hands-on guide that provides you with a number of clear, step-by-step recipes that will help you to unleash the capabilities of the Google Maps JavaScript API in conjunction with open source or commercial GIS servers and services through a number of practical examples of real world scenarios. This book begins by covering the essentials of including simple maps for Web and mobile, adding vector and raster layers, styling your own base maps, creating your own controls and responding to events, and including your own events.You will learn how to integrate open source or commercial GIS servers and services including ArcGIS Server, GeoServer, CartoDB, Fusion Tables, and Google Maps Engine with the Google Maps JavaScript API. You will also extend the Google Maps JavaScript API to push its capabilities to the limit with additional libraries and services including geometry, AdSense, geocoding, directions, and StreetView.This book covers everything you need to know about creating a web map or GIS applications using the Google Maps JavaScript API on multiple platforms.

This process is known as reverse geocoding, and it is the process of converting coordinates to human-readable addresses.

In this recipe, we will make use of the reverse geocoding capabilities of the Google Maps JavaScript API. When the user clicks on the map, we will find the address where the user clicked and imminently display it to him/her.

Getting ready

Reviewing the recipe Drawing shapes on the map in Chapter 6, Google Maps JavaScript Libraries, will ease your work because greater detail on drawing shapes and their background is required for this recipe.

How to do it…

Here are the steps to allow your user to click on the map and find the address of the place that he/she clicked on:
