Accuracy Assessment of Remotely Sensed Data (Part 5 of 7)

This video from AmericaView is part of a series that explores the process of assessing the accuracy of maps made from remotely sensed data. In the video, Russell G. Congalton from the University of New Hampshire explores reference data collection for thematic accuracy. After the lesson, learners will be able to address the following components of effective reference data collection: classification scheme, sample unit, sample size, costs, sampling scheme, the source of the data, the method for collecting the data, timing of the collection, and methods for ensuring consistency and objectivity. The video recording runs 22:52 minutes in length.
