Assessing the accuracy of remotely sensed data


Do you know how much to trust an imagery-based map layer? Have you conducted a thorough accuracy assessment of a map you produced with remote sensing? Accuracy assessment has become an essential component of any mapping project and it must be clearly and effectively planned from the beginning of a project in order to be as cost-efficient as possible. This webinar will present an overview of the issues and considerations necessary to assess the accuracy of a map generated using remotely sensed data. While it is not possible to provide all details related to accuracy assessment during this webinar, this overview will provide an excellent starting point from which the attendee can find additional resources.


Russell G. Congalton, PhD, Professor of Remote Sensing & GIS, Dept. of Natural Resources & the Environment, University of New Hampshire, Director, NHView

Dr. Congalton has over 30 years of research and teaching experience in remote sensing, GIS, and other geospatial technologies.  His seminal research in spatial data uncertainty, accuracy assessment, and validation of geospatial data is internationally known and recognized. Currently, he is the director of New Hampshire View – a part of the America View Consortium dedicated to promoting the use of remote sensing and other geospatial technologies throughout the US.


This webinar is brought to you by eXtension Map@Syst, NHView, NH Space Grant Consortium, UNH Cooperative Extension and the Vermont Center for Geographic Information.
