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.

Creating a table of contents control for layers


Table of Contents (ToC) controls such as UI elements are very common in desktop GIS software, such as ArcGIS Desktop, Mapinfo, and Geomedia. Also, their web counterparts make use of ToCs intensively in their UI, including ArcGIS and .Net web components.

The main use of ToCs is to turn On and Off the various raster or vector layers so as to overlay and view multiple strata of data. For vector layers, the options might be enriched by allowing the users to change the symbology of the vector layer with respect to ToCs.

The Google Maps UI does not have a built-in ToC control; however, with the flexibility of building up a custom control, there are virtually infinite possibilities.

The Google Maps JavaScript API allows developers to utilize the third-party base maps such as OpenStreetMaps or display the overlay raster layers on top of base maps (discussed in detail in Chapter 2, Adding Raster Layers). Also, in Chapter 3, Adding Vector Layers, various...
