Burned area mapping in greece using SPOT-4 HRVIR images and object-based image analysis

Abstract

The devastating series of fire events that occurred during the summers of 2007 and 2009 in Greece made evident the need for an operational mechanism to map burned areas in an accurate and timely fashion to be developed. In this work, Système pour l'Observation de la Terre (SPOT)-4 HRVIR images are introduced in an object-based classification environment in order to develop a classification procedure for burned area mapping. The development of the procedure was based on two images and then tested for its transferability to other burned areas. Results from the SPOT-4 HRVIR burned area mapping showed very high classification accuracies (~0.86 kappa coefficient), while the object-based classification procedure that was developed proved to be transferable when applied to other study areas. © 2012 by the authors; licensee MDPI, Basel, Switzerland.
