Landscape regionalization by automatic classification of landform elements
Norsk Geografisk Tidsskrift - Norwegian Journal of Geography, 1997The landscape is a complex surface influenced by a variety of factors (e.g. vegetation, soil, geology, land use and human impacts) in addition to topography. The realization of the importance of the topography in determining a range of physical processes, however (Moore et al. 1991, Pennock et al.

Hydrogeomorphic approaches to wetland classification use landform classes to distinguish wetland functionality at a regional scale. Space-borne radar technology enabled faster regional surveying of surface elevations to digital elevation models, which allowed for automated terrain attribute and landform classification using geographical information ...

The Natick Landform Classification System
1974Abstract : This report provides a description of the landform classification system developed by the US Army Natick Laboratories for AMSAA environmental evaluations, employing maximum hill height, model hill height, and number of positive features per mile as criteria, together with the development rationale and limitations.

The impact of data normalisation on unsupervised continuous classification of landforms
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Although most clustering techniques that characterise output classes by mean vectors and a covariance matrix require that features are roughly Gaussian, feature assessment for normality is often ignored in the classification process. This paper presents an example of the effect of data transformation on unsupervised continuous classification of ...

An approach to DEM analysis for landform classification based on local gradients
Earth Science Informatics, 2018In this paper we propose an exploratory methodology, devoted to classify the pixels of a Digital Elevation Model (DEM), to be used as a morphometric basis for studies in other frameworks. The aim is to classify the terrain units according to eight topographical local gradients, computed as differences between each pixel and the eight surrounding ones ...

ON A LANDFORM CLASSIFICATION AND SOME PROBLEMS OF TERMINOLOGY
Soviet Geography, 1975A paleogeomorphologist proposes a classification of the earth's landforms that would reflect the shaping of surface relief as a continuous process since the beginnings of the earth. In his view, the relief of former outer surfaces of the earth, now invisible to the observer, needs to be included in such a classification on the same basis as the relief ...

Geomorphons — a pattern recognition approach to classification and mapping of landforms
Geomorphology, 2013Abstract We introduce a novel method for classification and mapping of landform elements from a DEM based on the principle of pattern recognition rather than differential geometry. At the core of the method is the concept of geomorphon (geomorphologic phonotypes) — a simple ternary pattern that serves as an archetype of a particular terrain ...

Glacial Landform Classification with Vision Transformer and Digital Elevation Model
IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing SymposiumKlasyfikacja polodowcowych form rzeźby terenu jest zagadnieniem w geomorfologii, które nie było szeroko badane za pomocą metod głębokich sieci neuronowych. W niniejszym opracowaniu wykorzystano architekturę Vision Transformer (ViT) do klasyfikacji lodowcowych form terenu przy użyciu cyfrowego modelu wysokościowego (DEM) w trzech badanych miejscach ...

Landform classification based on adjacency index of feature lines
SPIE Proceedings, 2007Landform feature points and lines have been used as basic landform descriptors of landform skeleton in many fields, including surveying, simulation of hydrology, landform classification, and vegetation mapping. With the objective of landform classification from DEMs, an approach has been put forward based on topological parameters and the extended ones.

Automatic Recognition of Landforms on Mars Using Terrain Segmentation and Classification
2006Mars probes send back to Earth enormous amount of data. Automating the analysis of this data and its interpretation represents a challenging test of significant benefit to the domain of planetary science. In this study, we propose combining terrain segmentation and classification to interpret Martian topography data and to identify constituent ...
