AbstractTo facilitate the delineation of eskers within an object-based image analysis environment, an experimental classification procedure is defined. Semantic and statistical methods are developed in order to investigate the applicability of defining glacial landforms within an object based image analysis framework. Landsat Enhance Thematic Mapper Plus (ETM+) and Digital Elevation Models (DEM) are used within the modelling environment to characterize the esker landform both morphometrically and spectrally. The use of DEM derivatives greatly increases the ability to describe an esker object in terms of relative position in the landscape. Results indicate that the esker landform can be successfully extracted; however, further research is required to reduce errors of commission.
