The Google Maps API remains one of the showcase examples of the Web 2.0 development paradigm, making it fairly trivial for third-party developers to incorporate dynamic mapping services into Web applications. In fact, interest in the Google service is so strong that it arguably sparked the mashup phenomenon, along with a number of websites such as http://www.gmapsmania.com intended to highlight some of the exciting applications developers are building using the mapping API in conjunction with a variety of other data sources. Beginning Google Maps Applications with Rails and Ajax is the first book to comprehensively introduce the service from a developer-perspective, showing readers how they can integrate mapping features into their Rails-driven Web applications. Proceeding far beyond simplistic map display, readers are shown how to draw upon a variety of data sources such as the U.S. Census Bureau s TIGER/Line data and Google's own geocoding feature to build comprehensive geocoding services for mapping many locations around the world.Readers are also guided through various examples demonstrating how to encourage user interaction such as pinpointing map locations, adding comments, and building community-driven maps.

The first four chapters take you through building an application, similar to the author's hotspotr application where a user can save Wifi hotspot information. For many people this may be all they are looking for, a way to create maps, save information and geocode addresses.
Chapters 5-8 deal with larger datasets and the example they use is from the FCC Antenna Structure Registration, which has 120k records already geocoded for you. It then takes you through different presentation methods. If you want to see the output, go to book dot earthcode dot com chapter seven, server custom tiles. It's a very impressive result, similar to the pictures of earth at night.
The rest of the book gives other advanced uses and apis, I have not read all the way through that but it looks interesting. The other thing I like about the tone of the book is the conversational style. For example in Chapter 5 where they are using the FCC dataset they talk about the advantages of using a mysql import instead of going through the ActiveRecord layer, resulting in importing the data in less than a minute compared to 1.5 hours with ActiveRecord. This is the type of information that usually only comes from time spent trying different methods, so it's nice for us to be able to leverage their hard work.
In general I have been impressed with the Apress books ( no pun intended) them and Pragmatic Programmers have really started giving O'Reilly a run for their money.
I develop Rails applications and became interested in Google Maps in conjunction with a Real Estate application I was working on. In particular, I was interested using Google Maps for visual analysis of large data sets. Knowing next to nothing about the Google Maps API, I was truly at the Novice level. The book started off at the basics and quickly built on example and technique to the point where there was a working example of a problem similar in scope to mine. Along the way, the trade offs and techniques were well presented and explained in detail. Not only did I gain the knowledge and confidence to tackle my particular problem, but I was also inspired by all the other potential applications of this exciting new technology.
This book was well organized and written. I was obvious that the authors had worked through the examples and I especially appreciated many of the best practices and hints they gave. Chapter 7 "Optimizing and Scaling for Large Data Sets" was particularly interesting for me and my application. It included code and examples for several server-side and client-side techniques and as well as a clear explanation of their uses and trade offs.
If you are a Rails coder and you want to master Google Maps, this is a must have book
If you are trying to implement google maps on rails, I'd recommend maybe getting the Apress book on the GMaps API v3, and then just relying on Google/Stack Overflow to figure out how to integrate it into Rails. There doesn't seem to be any good books that provide this at the moment.
