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.

Adding image overlays to maps


Overlaying tiled map services is a big capability on hand. It enables a variety of tiled map services that come into the scene using the Google Maps API. The existing stock of tiled map services are, in general, global map services, which means that they cover the whole world or at least some continent/country.

We may be interested, for instance, to overlay a map for a university campus, having its rough plan on hand. Or, we may have found some map of a historical sheet and want to make use of it. Or, we may have an internal building plan of a particular building and we would like to see this building plan on top of Google Maps.

Is it possible to overlay these microscale images on top of Google Maps? Yes, certainly! In fact, technically, there would be no difference between using campus plans or building plans instead of tiled map services as overlays. The important thing to note is that those plan sheets should be aligned as tiles similar to the tiled map services...
