Object attribute Description FID The ID number of the object Area_Pxl Area of the object measured in cells (1 cell is appr. 1 km²) Asymmetry Relative length compared to a regular object. The higher the value, the higher the asymmetry of the object is Border_ind Border index measures how jagged an object is. It is calculated as the ratio between the border(More)
—In most landform classification studies – either per cell or object-based – the authors have ignored modeling the semantics of landforms explicitly. Thus, landform classification schemes rely on individual knowledge, and are too much tailored to specific areas and/or scales. Integration of structured knowledge models in the classification process has been(More)
Earth surface processes operate on various spatio-temporal scales and produce landforms that are structured in a nested hierarchical manner. Semi-automated extraction of selected landform types from digital elevation models (DEMs) is of great importance in geomorphology. Object-based image analysis (OBIA) provides an attractive framework for multi-scale(More)
—Landform mapping is more important than ever before , yet the automatic recognition of specific landforms remains difficult. Object-based image analysis (OBIA) steps out as one of the most promising techniques for tackling this issue. Using the OBIA approach, in this study, a multiscale mapping work-flow is developed and applied to two different input data(More)
