Validation, also called accuracy assessment, is a critical step in the use and distribution of the results of analyses of remotely sensed data. These lessons describe the steps involved in accuracy assessment and methods for providing estimates of accuracy. Use the sub-menu to the right or the menu bar above to navigate to the lessons. Because the accuracy of remotely sensed data is critical to any successful mapping project, accuracy assessment is an important tool for anyone who uses remote sensing. This is a complete guide to assessing the accuracy of maps generated from remotely sensed data, and the only book available that is devoted solely to this complex topic.
