Assessing the Accuracy of Remotely Sensed Data: Principles and Practices, Second Edition (Mapping Science)

The field of assessing the accuracy of maps derived from remotely sensed data has continued to develop and mature since the first edition of this book was published in 1999. The original eight chapters have been expanded to eleven. Of most significance is a new chapter that covers positional accuracy. The accuracy of any spatial data set is a combination of both the positional accuracy and the thematic accuracy. Therefore, a complete presentation of how to assess the positional accuracy of a map has been added along with a discussion of the impact of positional accuracy on thematic accuracy. The use of fuzzy accuracy assessment has increased since the first edition, and we have included an entire chapter on this important process. Also, the chapter on assessing the accuracy of a map of change detection has been expanded with a more thorough discussion of the special sampling issues that must be considered to effectively assess the change. Finally, a new case study has been presented that is up-to-date and reflects the complications and issues one would face when conducting an accuracy assessment today.
