Accuracy Assessment and Validation Validation also called accuracy assessment is a critical step in the use and distribution of the results of analyses of remotely sensed data. You may need aerial photos or. But if we need a reliable accuracy assessment we cant do without quantitative methods of evaluation.

An appropriate accuracy measure is usually needed to tune free parametersthreshold and to evaluate. Productive utilization of geodata is only possible if the quality of the data is known. Accuracy assessment and validation is essential in remote sensing-based projects since decision making or scientific analysis with data of unknown or little accuracy will result in information with low reliability error propagation effects and subsequently be of limited value. But if we need a reliable accuracy assessment we cant do without quantitative methods of evaluation. Accuracy assessment is an important part of any classification project. Principles and Practices is thoroughly updated and includes five new.

Ground truth can be collected in the field.
