A landform is a physical feature of the terrain with its own recognisable shape. Its definition is often qualitative and inherently vague. Hence, landforms are difficult to formalise in a logical model that can be implemented. We propose for that purpose a framework where these qualitative and vague definitions are transformed successively during different phases to yield an implementable data ...

Automatic procedures for landform extraction is a growing research field but extensive quantitative studies of the prediction accuracy Landform Classification (ACL) based on direct comparison with geomorphological maps are rather limited. In this work, we test an algorithm automatic classification large sector Ionian coast southern Italian belt through detailed map. was performed by using indiv...

background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

Bedrock mega-grooves (BMGs) are subglacial landforms of erosion that occur in glaciated terrain various geological and (palaeo)glaciological settings. Despite a significant literature on BMGs, no systematic morphometric analysis these has been undertaken. This is necessary step towards exploring BMG formation successfully applied to other similar magnitude (e.g. mega-scale glacial lineations (M...

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 proposed to overcome the limitations in...

Terrestrial paleoclimate records rely on proxies hosted in alluvial strata whose beds are deposited by unsteady and nonlinear geomorphic processes. It is broadly assumed that this renders the resultant time series of terrestrial paleoclimatic variability noisy and incomplete. We evaluate this assumption using a model of oscillating climate and the precise topographic evolution of an experimenta...
