Product Description
Since the dawn of creation, man has designed maps to help identify the space that we occupy. From Lewis and Clark's pencil-sketched maps of mountain trails to Jacques Cousteau's sophisticated charts of the ocean floor, creating maps of the utmost precision has been a constant pursuit. So why should things change now?

Well, they shouldn't. The reality is that map creation, or "cartography," has only improved in its ease-of-use over time. In fact, with the recent explosion of inexpensive computing and the growing availability of public mapping data, mapmaking today extends all the way to the ordinary PC user.

"Mapping Hacks," the latest page-turner from O'Reilly Press, tackles this notion head on. It's a collection of one hundred simple--and mostly free--techniques available to developers and power users who want draw digital maps or otherwise visualize geographic data. Authors Schuyler Erle, Rich Gibson, and Jo Walsh do more than just illuminate the basic concepts of location and cartography, they walk you through the process one step at a time.

"Mapping Hacks" shows you where to find the best sources of geographic data, and then how to integrate that data into your own map. But that's just an appetizer. This comprehensive resource also shows you how to interpret and manipulate unwieldy cartography data, as well as how to incorporate personal photo galleries into your maps. It even provides practical uses for GPS (Global Positioning System) devices--those touch-of-a-button street maps integrated into cars and mobile phones. Just imagine: If Captain Kidd had this technology, we'd all know where to find his buried treasure!

With all of these industrial-strength tips andtools, "Mapping Hacks" effectively takes the sting out of the digital mapmaking and navigational process. Now you can create your own maps for business, pleasure, or entertainment--without ever having to sharpen a single pencil.

About The Author
Schuyler Erle was born in a small paper bag in Philadelphia, and then again five days later in Baltimore. As a youth, he had to get up every morning two hours before he went to bed in order to walk fifteen miles uphill to school, and then another seventeen miles uphill to get home in the evening. After many years of some nonsense involving Karnaugh maps, a botched attempt at a Red Cross sailing certificate, and the early works of Chomsky, Schuyler was finally and at long last sent packing with something his mentors found at the bottom of a Cracker Jack box. Later, after a tragic accident that left him nearly completely lacking in common sense, he served brief stints on Phobos and Ganymede with the Space Patrol, before returning to study n-dimensional unicycle frisbee golf at a yak herding collective in Miami. Somewhere along the line he made the grave error of attempting to implement a full-scale multi-user web application using a combination of tcsh, awk, and sed, which lead him straight into the arms of O'Reilly & Associates, first as a reader, and then as an author and humble developer. Four years & fifty thousand miles later, we present him in his full and unabridged form, where he hacks Perl behind the scenes at the O'Reilly Network, does on-site technical support for ORA's fine conferences team, is involved in a variety of database and production development projects across the company, and still manages to write and give conference talks for ORA from time to time.

Rich Gibson is a Perl/Database programmer in Santa Rosa. He has worked professionally with computers since 1982 when he created Public Utility Rate Case Models in SuperCalc on an Osborne II. His current fascination is creating tools to aid in the acquisition, management, and presentation of information with a geographic component. He is currently converting an old golf cart into a mobile geo annotation platform.Rich is active with the NoCat Community Network in Sebastopol, California, and is the primary developer of NoCat Maps (http://maps.nocat.net/).

Jo Walsh is a freelance hacker and software artist who started out building web systems for the Guardian, the ICA and state51 in London. She now works with the semantic web, spatial annotation and bots.

Reader Reviews
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 (SPLAT! instead of 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.
