HTML5 Geolocation by Anthony T. Holdener III

Upshot: Here is your intermediate guide to HTML5 Geolocation-centric APIs. Pros: Another straightforward O’Reilly intro to HTML5-like cutting edge hotness. Cons: None really. Code might change over time, so get the eBook for free updates.

If you need a quick introduction to Geolocation APIs available from Google, as well as ArcGIS, then HTML5 Geolocation is it.

However this book is not for beginners. You should be very comfortable coding HTML or Javascript as the as there is lengthy code (not just snippets) to get this magic to happen. It is nice that the code that does the magic has been thoughtfully called out and explained by the author.

The author also does a nice job of outlining just what Geolocation is (it’s not just a flat 2d map), what resources are available, as well as what resources can/need to be saved, and what you can do with that information. The breakdowns of the geo-specific code are very straightforward, and there is a LOT of code, so I recommend getting the eBook version.

Finally there’s a section on marketing & privacy and whether that still matters to the younger generation —and how/why all this social network-spacial relationship stuff works in context.

This book is NOT for absolute beginners. But if you’re already comfortable with HTML/Javascript, and SOME programming concepts, this book is a nice complement to HTML5 Up & Running, which I reviewed before. Highly recommended.

Disclosure: I received the eBook download from O’Reilly for review purposes.
