The first of its kind, Designing Geodatabases for Transportation is likely to remain the best of its kind. Al Butler has violated several "rules" of technical writing:
* He has opinions, isn't afraid to express them, and does so in an engaging, conversational style enlivened by war stories and thinking outside the polygon. Most technical texts have no discernible voice and read as dull as dirt (apologies to soil scientists).
* He pragmatically and mercifully separates "need to knows" from "nice to knows", steering the reader around minutiae only a true nerd could love; yet retains that deeper content in unobtrusive places. Many technical works overwhelm the reader with information, providing no indication of relative importance.
* He manages to make ArcObjects comprehensible to the non or new programmer by providing simplified object model diagrams.
* He demystifies the arcana of internal ArcGIS data types, relationship classes, and other poorly explained (elsewhere) geodatabase concepts.
* Most importantly, he maps geodatabase structures to their counterparts in relational database theory. The more you understand the relational database foundation of the geodatabase, the better you'll be at designing them--this section alone makes the book worthwhile. If you're a database person adding the Geographic to your Information Systems background, this book will greatly aid your transition.
As for the transportation content, it's all there--linear referencing, dynamic segmentation, traffic counts, HPMS, editing and publishing data for State DOTs, network datasets and even geometric networks (typically not used for transportation purposes), the evolution of GIS transportation data models, etc.
Finally, and refreshingly, the author takes a one-size-does-*not*-fit-all approach, providing the reader a pick and choose, cookbook-like approach to suit individual need.
Still working my way through the book, but nodding my head in agreement more often than usual--a good indication, to me anyway, that the author:
* Knows his subject matter
* Has a gift for conveying that knowledge clearly to others.
* Has been out in the real world, solving real world problems
* Understands the business side of the Transportation house
Highly recommended to anyone interested in general geodatabase design, specific geodatabase design (transportation and possibly utility geodatabase design since linear referencing and networks play a role), and transportation GIS.
Al Butler was instrumental in helping develop the GISP certification program, and this book is another fine contribution to the GIS profession. We've not only needed this book--we need more books written like it. To my relief, it was and is not YASTMB--Yet Another Show-and-Tell Map Book. It's a practical how-to and reference for doing your job better.
Buy this book and buy copies for Transportation colleagues--they'll be asking to borrow yours, so get ahead of the game.
