While I enjoyed the author's clear writing style, and I was pleased to see that the level of detail and explanation given in each chapter is consistent, I did not find the book's content to be particularly valuable.

The book is organized very well, and it reads like a Google Maps tutorial, rather than a hacks book. The flow from chapter to chapter is similar to the Maps API online documentation, which makes following along with Google's documentation a breeze while reading the book.

The first 100 pages were introductory, describing Google Local, the Maps API, ways to store and share information, and so on in very general terms. This puts all users on equal footing, but it seemed odd to see so much basic information in a book about hacking Google Maps.

One thing that shocked me, especially given the approach taken in the first 100 pages, was to see all of the examples written in Perl. If the introductory lessons are needed by anyone, chances are that programming / scripting is new to him/her, and I don't see Perl as the appropriate language to learn at that point.

Version 1 of the API is used throughout the book, but version 2 was released in April 2006. Version 2 is largely backwards compatible, but Google has asked everyone to move to version 2, saying that v1 support can be turned off at any point. This doesn't take away from the value of the lessons, but it does add some overhead. I consulted Google's documentation and adjusted all of the books examples for the api changes as I read.

Another thing that particularly surprised me was the mention of using scraping techniques to extract geocoding data, without mentioning the drawbacks to doing so. Personally, I avoid scraping like the plague. There's no better way to break an app than to scrape its data. Geocoding is part of the v2 api, btw.

To summarize, the book is a clearly laid out introduction to using the Google Maps API, and it is written well, but I wouldn't recommend it to a friend. For an introduction to maps, I would consult Google's much-improved online documentation, and O'Reilly's "Google Maps Hacks" is a better read for what I would consider hacks (also written to api v1).

If you are primarily interested in Google Earth, use Web based resources. Material on Google Earth is limited and appears to be appended to a book written on Google Maps.

Although I really enjoy this book, it's too bad that it's already out of date (as mentioned in other reviews).

As someone with very little previous experience with JavaScript, I found this book to be really helpful it describing how to make stuff happen. I personally have found the Google Maps API Documentation to be far too terse and difficult to figure out; kinda like reading a dictionary to learn how to write.

This book takes the simplistic Google examples and builds on to them to give you a better idea of how you might actually build an application.

True, "Hacking Google Maps" might not be the best title for the book ("Introduction to Google Maps" might be more appropriate) but it was a very well written and useful book for getting my own Google Maps mash-up going.

I purchased this book to give me some insight into programming Google Earth solutions, however this book is 85% about Google Maps (the two are completely different). It took me about ten minutes to read the Google Earth content, and I learned essentially the same things I learned from browsing the Internet for a few hours. Disappointed, but at least I got the book for just a couple of bucks.

Google maps has lots of tool and features, some added after this book. But this is still a great book on what kinds of things you can do using Google Maps and Google Earth.

good book - it was a touch too technical for me. But I learned a good amount - if you have more computer experience - its a great read

Muitas dicas interessante, mas sem profundidade. Livro interessante para iniciantes, mas fraco para quem já conhece os recuros. Faltou também informação sobre o Google Earth.
