2.0 out of 5 stars
A major disappointment, January 15, 2006
This review is from: Mapping Hacks: Tips & Tools for Electronic Cartography (Paperback)
I really wanted to like this book, especially after all the glowing reviews it received. But the book has fundamental flaws in structure, topics, and approach:
- As someone else mentions, the book is heavily, albeit not exclusively, skewed towards Unix applications. Given that only 3% of desktops currently run Unix (6% if you're generous and include MacOS X), this immediately raises an accessibility barrier for those unfamiliar with the intricacies of Unix, and an unfamiliarity with Perl, Python, and shells. There are many Windows mapping applications that do much of what is described in this book far more easily and accessibly than the Unix-oriented solutions presented.
- Critical topics are defined incompletely and haphazardly. For example, while shapefiles are mentioned in several places early on, the first even barely-adequate definition comes several hundred pages into the text. Datums are covered very poorly, and given their importance in real-life applications, that's simply not acceptable.
- A significant fraction of the book is handed over to a discussion of different kinds of projections, and programs that will display them. While interesting, the fact is that most of the useful information about projections can be gotten from the text, or from a website that discusses projections; the "hacks" are essentially superfluous. I'm also disturbed by the amount of space given to projections vs. datums. In my experience, more people run into mapping issues with datums (e.g. using GPS units in WGS84, and wondering why they don't match up with topo maps in NAD27) than they do with projections.
- A huge chunk of the book is taken up GRASS. GRASS is very powerful, and as much fun to learn and use as sticking red-hot knitting needles into your eyes. Most of the problems that GRASS is used to solve in the book could far more easily be solved either with other freeware programs, or with Manifold GIS if you've got the money. For that matter, other difficult-to-use programs are employed to solve tasks that could be done more easily with other programs (e.g. SPLAT! is cited instead of the superior MicroDEM or RadioMobile for broadcast coverage; POV-Ray for 3-D models instead of 3DEM/Landserf/MicroDEM/Wissenbach3D; GRASS for map texturing instead of 3DEM or MicroDEM; PERL for spatial data analysis instead of GeoDA/STARS/PASSAGE; and so on). You could spend huge amounts of time becoming a "GRASS Ninja", as the book suggests, or you could spend less time and get more done using other software that's far easier to use.
- Sloppy terminology. For example, "Georeferencing" is used to refer to both linking digital photos to the location they were taken (should be "geotagging"), as well as its normal use in cartography, associating geographic coordinates with raster or vector features. And a GeoTIFF is not a Tiff with a world file, it's a Tiff with the georeferencing information embedded in it.
- A book of "hacks" should contain complete, self-contained hacks, and any number of hacks in this book don't fulfill this requirement. For example, the hacks on WMS/WFS, PostGIS, and building your own car computer/navigation system are either incomplete or hopelessly inadequate in giving you the information you need to implement them.
- Many of the hacks have been superseded by recent developments, like Google Maps/Earth, and the APIs from Yahoo and MSNLocal. This clearly isn't the authors' fault, but it does lessen the overall value of the book.
I could go on, but you get the idea. I have no idea of who the authors and publisher believe is the intended audience for the book, but unless you've got both a strong cartographic background and a strong Unix background, most of these hacks will be beyond you. And if you are strong in cartography and Unix, few of these hacks are even worth bothering with, since you'll most likely either know them, or know a better way to get them done. There are a few nuggets of useful information, primarily in the GPS section, but for most people, this book simply isn't worth the money.
Addendum (7/3/2011): The book is also now hopelessly out of date.

Value for beginners and experienced mappers alike..., July 22, 2005
This review is from: Mapping Hacks: Tips & Tools for Electronic Cartography (Paperback)
I found another book that's excellent if you're into maps and software that creates them... Mapping Hacks - Tips & Tools for Electronic Cartography by Schuyler Erle, Rich Gibson, and Jo Walsh (O'Reilly). You can have a lot of fun with this one...
Contents: Mapping Your Life; Mapping Your Neighborhood; Mapping Your World; Mapping (on) the Web; Mapping with Gadgets; Mapping on Your Desktop; Names and Places; Building the Geospatial Web; Mapping with Other People; Index
What's nice about this book is that it's not all about installing some large mapping software package and then learning how to use it. Mapping Hacks covers a wide array of mapping techniques, tricks, and hacks that can be used by anyone willing to sit down and try things out. For instance, the first hack (#1 - Put a Map on It) shows you how to use the online mapping services and how to hack together a URL to add mapping to your website. Ever wondered how those driving direction sites work? Hack #2 - Route Planning Online - sheds light on that one. They even go so far as to cater to the ultra-geek and explain how to build a car navigation system that "will consume all your time and money, but make you the envy of all your nerd friends". Gotta love it...
Like O'Reilly's other mapping book, this is printed in color, so you get a lot of information from the context of the figures and graphics. Nicely done. The book is also larger than a normal Hacks title. There's the standard 100 entries, but there's around 525 pages to it. You get a lot of detail on some of the more complex hacks, which in my opinion adds a lot of value to the book.
A perfect book for those looking to get their feet wet on the subject, as well as for those who are more experienced but want to learn a few new tricks. Very nicely done...

A Far Cry from the Texaco Gas Station Maps!, July 6, 2005
This review is from: Mapping Hacks: Tips & Tools for Electronic Cartography (Paperback)
Nowadays it isn't about simply getting information about a place or location, thanks to the recent explosion of personal-GPS units, online mapping and free and low-cost satellite imagery the latest trend is to transform information into a map to present the information in a more dynamic and sometimes more usable way.
Mapping Hacks is a unique book in that it will take you far beyond simply bringing up a map of Grandma's house. It will show you how to take data that you collect and use it to present maps and cartographic data about everything from mapping the wi-fi hotspots in your area, to tracking a package as it moves across the globe to creating 3-D maps of your neighborhood, your city and even the entire planet. This book is for those who aren't simply satisfied with the basic information MapQuest or Google Maps provide, but want to take that information and use it in ways that were unheard of just a few months ago.
Though having a GPS unit to collect data is a great way to get the most out of this book, there are also plenty of hacks devoted to simply mapping out or building on top of existing data. Perhaps you want to setup a web site that shows all the local eateries in your neighborhood along with their latest health report -- no problem, there is a hack that will walk you right through it! This book helps open your mind to the possibilities of what all you can do with the data you already have. You may implement the hack for the health code violations and then build from that to start mapping out housing prices, or crime statistics -- the possibilities are endless.
Unfortunately, the book does not cover the latest API into Google Maps -- one of the recent, and more popular resources for mappers. However, the book does cover a lot of the more traditional ways of accessing sites like MapQuest and Yahoo Maps. It was written so that you don't have to be a programmer or computer guru to get the most out of the book.
It's a unique book (and in full color too I might add) that really will open your eyes and mind to the new ways of using services and information that once was only accessible to map makers and businesses.
