Independent validation data are required to assess the accuracy of Earth Observation for Sustainable Development of Forests (EOSD) land cover map products. Validation of EOSD products can be undertaken using samples collected from airborne video data. The validation chips are video frames selected at regular time intervals from the continuous video data. Manual attribution of the video samples is required to enable the use of the video chips to assess the accuracy of the EOSD land cover projects. This document provides a description of the process of attributing video chips and guidelines for using the video data in validation efforts. A description of the EOSD legend classes are provided along with the hierarchical scheme used for class definition. Methods are also provided for selecting primary and secondary classes and, guidelines for determining forest density classes and mixed forest classes. To aid in consistent attribution, an identification key, which includes representative samples from the video, is provided. The background and recommendations in this document are designed to develop a consistently attributed validation data set for land cover applications.
