In the work is exposed a methodology for the morphostructural classification of the Cuban archipelago in the context of the lithospheric plates of the Caribbean, Northamerican, Cocos and Nazca. This classification, with six hierarchic levels, has

The technique devised for this archaeological study relied on a simple, qualitative, visual classification of weathering, and a photo interpretation mapping system of large sample areas. Schmidt hammer tests were used to verify the accuracy
of the visual assessment and to provide a quantitative basis for the weathering classification.
Etude de la classification des unités géomorphologiques fondamentales (plaine, plateau, colline, montagne...). Deux types de classification sont proposés, analysés et critiqués.

Computer analysis of integrated digital data sets can be exploited for geomorphologicalclassification using automated methods developed in the remote sensing community. In this study, geomorphologicalclassification in a moderate- to high-relief
area dominated by slope processes in southwest Yukon Territory, is performed with a combined set of geomorphometric and spectral variables in a linear discriminant analysis. An automated method was developed to find the boundaries of geomorphological
objects and to extract the objects as groups of aggregated pixels. The geomorphological objects selected are slope units.
This paper presents an expert-driven semi-automated method to define geomorphological units in a partly forested alpine area in Austria, using detailed statistical information derived from a laser DTM and an object-oriented classification approach
. The identified geomorphological units are directly linked to morphometric properties, material, surface processes and the genesis of landforms. Recognition of these units is not based on individual landforms (e.g. a drumlin, a landslide and a single gully

A National Park Survey in Western Samoa : Terrain classification on tropical volcanoes in Applied geomorphological mapping : methodology by example.
A reconnaissance survey of a proposed National Park in Western Samoa employed techniques of terrain classification largely based on geomorphology. This provided a data base of maps and Land System descriptions valuable in establishing and managing
the Park. It also enabled a rapid production of geological and soils maps. As a side issue the geological and geomorphological history was determined.
Taking into consideration mechanisms of the glacial relief formation the classification of such a relief based on its genesis distinguishes 2 principal categories: glacial destructional relief and glacial constructional one. The former includes sub

The lakes are separate on Czech Republic area in natural and anthropogenic origin. The geomorphological viewpoint prevails by glacial, fluvial, karst, dammed-up by landslides, organogenous and anthropogenic lakes. As the anthropogenic lakes
Morphological typifications of Slovenia's surface using global classification methods

Morphology is often the most important factor in distinguishing landscapes and is an important element in geographical classifications, typifications, and regionalizations. Therefore, morphological divisions of the surface have a long tradition
in Slovenia and abroad. This article presents examples of foreign methods of global surface classification of Slovenia and compares them to the established Slovenian typification of Slovenia’s surface. - (IKR)
The AA. investigated geomorphological features on the central plain of Thailand utilizing satellite remote sensing data and made geomorphological land classification map showing flood-stricken area. This map is useful for planning of flood control
works. The AA. classified land form units in the central plain of Thailand as following; delta, tidal flat, lagoon, mud spit, back marsh, natural levee, fan and former river course and so on. After that they transfer geomorphological land classification
Effects of variable attribute weights on landform classification

This paper focuses on the attribute weight issue and advocates use of modifiable attribute weights in terrain-based environmental analysis and classification. As an example, the effects of modifying attribute weights were evaluated for fuzzy k-means
landform classification in a case study area. A total of 102 classifications were compared with each other and with a soil map, and comparison methods were specifically designed to evaluate the differences between these classifications. The results show
that fuzzy k-mean landform classification is sensitive to weight adjustments of adopted terrain attributes.
