This second edition of an already excellent reference is essential to anyone working in datums and projections. I am not aware of another work with the scope and clarity of this text.

This book has great information about coordinate systems and I believe it is the best in this field by its simplified ideas

The book is very good but did not provide me with enough information to do what I want, namely to convert between WGS84, NAD27, and NAD83. It helped me understand how to do it, and why the steps were needed, but did not provide the essential data - axis lengths and transformation parameters. I will hopefully find this data on the Internet, maybe on the NOAA or OGP sites.
