And from the third edition, thanks to Dr. Henry Driver of Computer Sciences Corporation for details
relating to the calculation of geodetic position in Chap. 2. Thanks also to the users and reviewers who made
suggestions for corrections, additions, and improvements. Errors should not occur, but they do, and the author
would be grateful if these are drawn to his attention. He can be reached at droddy@tbayel.com.
The editorial team at McGraw-Hill has contributed a great deal in getting the fourth edition into print:
thanks are due to Steve Chapman, the sponsoring editor; Diana Mattingly, editorial assistant; and Gita Raman,
project manager, for their help, and their gentle but persistent reminders to keep the book on schedule.
