This book does offer a wealth of information about a number of the most popular software titles for GPS mapping. It would be particularly useful for those who haven't already chosen the software they want to use as these tutorials will allow a reader to get the feel of the software before making a choice. There are a few very good pieces of mapping software that aren't covered in the book, however. Still, it is worth the price just to compare.
