ASPECTS OF THE COASTAL GEOMORPHOLOGY OF LES ILES DE LA MADELEINE USING REMOTE SENSING TECHNIQUES

Abstract

Remote sensing imagery has proven useful in studying the coastal geomorphology of les Iles de la Madeleine. Standard panchromatic photography provided the basis for mapping of the island and aided in the interpretation of the evolution of this tombolo system. This study presents a systematic evaluation of five types of remotely sensed data: (1) colour infrared photography, (2) conventional colour photography, (3) panchromatic photography (red and green bands), (4) black and white infrared photography and (5) thermal line scan imagery as applied to the southern portion of les Iles de la Madeleine. The results of this study have shown that beach investigations are enhanced through the use of multisensor imagery, and that colour infrared provides the best single source for data aquisition.
