The article describes the main spatial properties of traditional cultural landscape of the Evenks in South Yakutia. The study is based on the of field research conducted on key areas of Evenks in South Yakutia – interviews, representation modelling, observations – and the use of Sentinel 2A remote sensing for mapping and contextualising the...

In the last years of the 20th century and the beginning of the 21st century, the number of flooding and ice-flooding impacting the populated areas of the Republic of Sakha (Yakutia) has significantly increased. This present research analyses the long-term hydrological data and the features of the ice drift on the average Lena for the period...

This paper proposes a vulnerability assessment of the Yakutsk areas exposed to the spring breakup flood. The approach is based on the use of remote sensing and a GIS's multi-criteria analysis. Before assessing the vulnerability, potential flood-prone areas have been model with data from Global Digital Elevation Model (GDEM) ASTER v.2...

Currently, there are many approaches to the recognition of urbanized areas, mainly based on the methods supervised and unsupervised spectral image classifications. D. Statakis, K. Perakis, I. Yu. Savin proposed an index (VIBI - Vegetation Index - Built up Index), which is a combination of widely known NDVI and NDBI. In this article, we will...

The landscape-indicative approach makes it possible to determine permafrost landscapes based on the identification of two physiognomic indicators-variables of relief and vegetation, as well as stratigraphic-genetic sediment complexes. For permafrost characteristics of landscapes, multilevel combinations of environmental variables (criteria) for...

Currently, the analysis and monitoring of the sustainability of subarctic landscapes in the context of global climate change and continuous permafrost, requires accurate methods for determining the spatial organization of each taxonomic of landscape units. In this article, we present an approach based on the recognition and characterizing the...

Mapping of permafrost mountain landscape of Verkhoyansk in the Arctic zone is based on the recognition by remote sensing and GIS modeling of the landscape permafrost-objects resulting from the combination of the Milkov's taxonomic classifications. The methodology developed integrates three types of modeling: the...

Approaches of geographic ontologies can help to overcome the problems of ambiguity and uncertainty of remote sensing data analysis for modeling the landscapes as a multidimensional geographic object of research. Image analysis based on the geographic ontologies allows to recognize the elementary characteristics of the alas landscapes and their...

The landscape taxonomy has a complex structure and hierarchical classification with indicators of their recognition, which is based on a variety of heterogeneous geographic territorial and expert knowledge. This inevitably leads to difficulties in the interpretation of remote sensing data and image analysis in landscape research in the field of...

The Lena River is the major axis that structures a part of central and oriental Siberia. Real motorway in winter and seaway in summer, it is the only way that allows the goods transportation in quantity. More than 40 % of the Saka Republic (Yakoutia) inhabitants live along the Léna. It was the main antropisation axis and is the main...

Arctic extensively urbanized centers are subject to the impact of many negative environmental phenomena progressing in terms of global climate change and regional development in Yakutia in the context of poor and missing databases. For this reason, the modeling of the risk exposures is based on combining the remote sensing, and local knowledge...

The aim of the research is to analyze the landscape structure of the eastern slope of the Orulgan ridge using complex geoinformation modelling. We use the field surveys data made in 2018-2019. The geoinformation modelling technique consists of the supervised pixel-based classification of time series remote sensing data of Landsat 8 OLI/ TIRS...

This article discusses the spatial organization of permafrost landscapes on the eastern slope of the Orulgan ridge in the area of lake Bulgunnyakhtakh. The study was based on a comprehensive physical and geographical description of facies and on the analysis of various cartographic and literary sources. Based on the results of the study, a...

In this article authors analyse natural and cultural landscapes for scientific tourism. Central Yakutia with the unique permafrost landscapes is a rich and large territory of sites of interest for the development of "scientific tourism" for explorers, researchers or eco-natural-tourists. There are three types of scientific tourism relevant for...
