Accuracy assessment of maps derived from remotely sensed data has continued to grow since the first edition of this groundbreaking book. As a result, the much-anticipated new edition is significantly expanded and enhanced to reflect growth in the field. The new edition features three new chapters, including:
Fuzzy accuracy assessment
Positional accuracy
Case study: Mapping land cover and land use in the Florida panhandle
The authors provide a complete presentation of how to assess the positional accuracy of a map along with a discussion of the impact of positional accuracy on thematic accuracy. They also include a more thorough discussion of the special sampling issues that must be considered to effectively assess change.
Complete with a 16-page color insert, this second edition continues to provide a complete guide to designing and conducting a state-of-the-art accuracy assessment.
