A detailed analysis of the Viñales National Park (VNP) was carried out to evaluate main geosites geomorphological interest inside park. This allowed selection areas (AIG) and localities (LIG) with 20 geological (PIG) suitable their importance as geoheritage. Moreover, three field trips one virtual itinerary encompassing park aimed improve geological–geomorphological knowledge be used in geotour...

Abstract The Svea coal mines in Svalbard have been closed, and the area is under restoration. goal of landscape restoration was to enable dynamic ecological geomorphological processes by removing roads, housing, industrial facilities, airports, landfills, quarries that once dominated area. Cultural heritage features, such as pre-1946 buildings, structures, mining traces, preserved, while rest h...

The Ethiopian region records about one billion years of geological history. The first event was the closure of the Mozambique ocean between West and East Gondwana with the development of the Ethiopian basement ranging in age from 880 to 550 Ma. This folded and tilted Proterozoic basement underwent intense erosion, which lasted one hundred million years, and destroyed any relief of the Precambri...

Polygon-based terrain classification data were created globally using 280 m digital elevation models (DEMs) interpolated from the multi-error-removed improved-terrain DEM (MERIT DEM). First, area segmentation was performed globally with the logarithmic value of slope gradient and the local convexity calculated from the DEM. Next, by adding surface texture, k-means clustering was performed globa...

High-resolution images of the seabed obtained with the use of hydroacoustic measurements allow a detailed identification of inaccessible seabed areas such as the Hans Glacier foreland in the Hornsund Fjord on Spitsbergen. Analyses presented in the paper were carried out on a Digital Elevation Model (DEM) of the bay’s seafloor exposed in the process of deglaciation, obtained from bathymetric dat...

V. GRADINARU AND R. HIPTMAIR † Abstract. Conforming finite elements inH(div; Ω) andH(curl; Ω) can be regarded as discrete differential forms (Whitney–forms). The construction of such forms is based on an interpolation idea, which boils down to a simple extension of the differential form to the interior of elements. This flexible approach can accommodate elements of more complicated shapes than ...
