In the history of the Internet, 2005–2006 will be remembered as the year when online mapping finally came of age. Prior to 2005, MapQuest and other mapping services allowed you to look up directions, search for locations, and map businesses, but these searches were limited, usually to the companies the services had partnered with, so you couldn’t search for any location. On February 8, 2005, Google changed all that. As it does with many of its services, Google quietly released the beta of Google Maps to its Labs incubator (http://labs.google.com) and let word-of-mouth marketing promote the new service. By all accounts, Google Maps was an instant hit. It was the first free mapping service to provide satellite map views of any location on the earth, allowing anyone to look for familiar places. This started the “I can see my house from here” trend, and set the blogosphere abuzz with links to Google Maps locations around the world. Like other mapping services, Google Maps offered directions, city and town mapping, and local business searches. However, what the Google Maps engineers buried within its code was something that quickly set it apart from the rest. Although unannounced and possibly unplanned, they provided the means to manipulate the code of Google Maps to plot your own locations. Moreover, you could combine this base mapping technology with an
external data source to instantly map many location-based points of information. And all of this could be done on privately owned domains, seemingly independent of Google itself.
At first, mapping “hackers” unlocked this functionality, just as video gamers hack into games by entering simple cheat codes. They created their own mapping services using Google Maps and other sources. One of the first these was Housingmaps.com, which combined the craigslist.org housing listings with a searchable Google Maps interface. Next came Adrian Holovaty’s chicagocrime.org, which offered a compelling way to view crime data logged by the Chicago Police Department. These home-brewed mapping applications were dubbed “hacks,” since Google had not sanctioned the use of its code in external domains on the Web.
The major change came in June 2005, when Google officially introduced the Google Maps API, which is the foundation for this book. By releasing this API, Google allowed programmers the opportunity to build an endless array of applications on top of Google Maps. Hundreds of API keys were registered immediately after the announcement, and many sites integrating Google Maps appeared within days. The map mashup was born.
The Birth of the Google Maps Mania Blog.
The Google Maps labs beta site had been public for barely a month when I tried it for the first time. I was fascinated. While combing through the blogosphere looking for more information, I started to see a trend toward Google Maps hacks, how-to sites, Firefox extensions, and websites indexing specific satellite images. I thought that others could benefit from an aggregation of all of these ideas into one themed blog. Thus, my Google Maps Mania blog was born.
This book will provide you the means to take part in this evolution of the Web. I hope to be posting about the interesting and unique map creations that you build after reading this book. Your creations will inspire others to do similar things, and together, we will continue to grow the Internet, one mapping application at a time. Let me know if you build something cool!

Prior to discovering PHP, he was busy making a LEGO®Mindstorms kit play Connect 4. Currently, he maintains an activecommunity site for classmates, built mostly from home-brewed extensions to PunBB and MediaWiki. He has written about CSS for Position Is Everything, and occa-sionally participates in the css-discuss mailing list. He particularlyenjoys those clever layouts that mix negative margins, relative posi-tioning, and bizarre float tricks to create fiendish, cross-browser, flexible-width concoctions. These and other nontechnical topics are discussed on his weblog at uwmike.com.
Offline, he enjoys cooking, cycling, and social dancing. He has worked with We-Create, Inc.
on a number of PHP-based projects, and has a strong interest in independent web standards.
