Developing a Semantic Model of Glacial Landforms for Object- Based Terrain Classification – the Example of Glacial Cirques
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 terrain segmentation and classification. ...
متن کاملRogen moraine: an example of glacial reshaping of pre-existing landforms
Rogen moraine is widely distributed in the core areas of the former Scandinavian and Laurentide ice sheets. It is generally agreed upon that these gently arched, ice-flow transverse ridges can be used in reconstructions of paleo-ice-flow patterns and that they indicate a melted-bed or poly-thermal basal ice regime. However, the processes of ridge generation have been contentious. This study pro...
متن کاملTowards an Ontology of Landforms
The paper begins with the question “Do mountains exist?” It shows that providing an answer to this question is surprisingly difficult, and that the answer which one gives depends on the context in which the question is posed. Mountains clearly exist as real correlates of everyday human thought and action, and they form the archetype for geographic objects. Yet individual mountains lack many of ...
متن کاملConcentric crater fill in the northern mid-latitudes of Mars: Formation processes and relationships to similar landforms of glacial origin
Hypotheses accounting for the formation of concentric crater fill (CCF) on Mars range from ice-free processes (e.g., aeolian fill), to ice-assisted talus creep, to debris-covered glaciers. Based on analysis of new CTX and HiRISE data, we find that concentric crater fill (CCF) is a significant component of Amazonianaged glacial landsystems on Mars. We present mapping results documenting the natu...
متن کاملUsing GIS to Quantify Patterns of Glacial Erosion on Northwest Iceland: Implications for Independent Ice Sheets
Glacial erosion patterns on northwest Iccliind are quantified using a Geographic Information System (GIS) in order to interpret subglacial characteristics of part of northwest Iceland affected by ice sheet glaciation. Ice scour lake density is used as a proxy for glacial erosion. Erosion classes are interpreted from variations in the density of lake basins. Lake density was calculated using two...
