"...the earth is still not a regular shape. In fact, it is so unique that geophysicists have a specific word solely used to describe the shape of the earth--the geoid."
Alastair lays a foundation with simple definitions like this one, that he then builds on to explain even more complex concepts like "reference ellipsoids", "datum", and "projection", to name a few. Beginning with chapter 2 the author discusses the SQL Server 2008 geometry and geography data types in great detail. Alastair discusses the power of the spatial data types and he gives you insight into the limitations and "implementation quirks" of the different types. Consider the ring orientation limitation of polygons defined using the geography data type:
"To resolve this ambiguity [defining the inside of a polygon], when you define the points of a Polygon using the geography datatype, SQL Server 2008 treats the area on the 'left' of the path drawn between the points of a ring as being contained within the interior of the Polygon, and excludes any points that lie on the 'right' side of the ring."
Alastair excels at framing complex problems in simple terms that beginners can understand, and then building increasingly advanced and fully functional code samples. This book is a powerful reference that I keep nearby at all times. I only hope Alastair follows up with an advanced level book to share his knowledge of the more complex and complicated tasks that can be performed with geospatial databases.
Alastair, write a "Advanced" book on this topic and I'll buy it!
The book is very clearly written. All the examples I tried worked. As I said before, Mr. Aitchison does a great job of explaining very difficult concepts so that even someone completely new to the topic will understand. That's the goal of a beginners book and it is very well met.
Now I want to see Intermediate Spatial please?

It explains clearly and simply how to use spatial and is very through. He also has a good blog and the book helps you understand them in greater detail. Lots of worked examples and a clear and simple structure. Also shows how to use C# with.Net as well as just SQL to get the results you want.
If you are UK based then look at his bogs on how to use open Ordnance Survey data.
I was extremely happy with the service offered by Amazon in delivering this book. Besides, the content of this book is well organised and structured in a logical way. I would say, this book is for anyone who is willing learn and develop skills in the Geospatial technologies particularly in SQL Server 2008. This book has explained all the bits and pieces of GIS from very basic to high standards and therefore, it would be useful for beginners and GIS technocrats. I would highly recommended this book who are keen to learn new technologies and you will reap the benefits for the money paid in buying this book.
Alle Beispiele werden in C# und VB.Net präsentiert. Dabei werden auch Technologien, wie CLR-Integration angerissen.
