Planning and placement of recreational complexes is based on the accounting and inclusion of a large number of factors, many of which are not officially regulated. The work carried out in the study area of the recreation center and the tourist complex “Otrada” focused on identifying the features of the objects existing in this area; fixing and displaying the specifics of the terrestrial surface, water bodies, vegetation; the space occupied by the recreational complex, related infrastructure and communications networks to accommodate new facilities. In the process of visualization of recreational complexes, the analysis is based on results of topographic and geodetic surveys, which can reflect the actual situation of the study area. In this regard, the main purpose of the study was to obtain basic data for the subsequent visualization of objects of the recreational complex. The purpose of the engineering and geodesic works at the site was to obtain topographic and geodesic materials and data on the situation and terrain, existing buildings and structures and other planning elements. The following tasks were solved: conducting field topographic and geodesic measurements; data processing; and building a digital terrain model. The Federal Law “On the State Real Estate Cadastre” to determine the coordinates of characteristic points allows the use of the method of satellite geodetic measurements. In this regard, the topographic survey of the territory was carried out by modern geodesic technologies using global positioning systems and the technique of GPS survey in real time kinematics (RTK). Then came the cameral processing of the field materials and the creation of digital models of relief and terrain, drawing up a digital topographic plan of 1:500 scale with a cross section of the relief in continuous horizontals in 0.5 m in the coordinate system SK-13 and in the Baltic elevation system. The situation and the relief of the area, existing buildings, structures, ground and underground communications, as well as other planning elements were applied to the topographic plan of the scale. On the basis of the available material of measurements and post-processing, a 3D model of the entire recreational complex “ Otrada” was produced and the features of the placement of its individual recreational facilities were identified.

We underlined the underdevelopment of the theoretical and methodological foundations of the interdisciplinary study of resettlement systems in recreational areas and substantiated the objective need for ꢁidespread introduction of GIS into the processes of territorial analysis and planning of complex spatial systems. The purpose of the study ꢁas to consider the possibilities of using GIS tools in the processes of spatial analysis and planning of the settlement - system of the Crimean recreational area. Basing on this, ꢁe designated tꢁo main research blocks to revieꢁ the existing and prospective structure of the Crimea settlement system ꢁith an emphasis on resort settlements. The methodological logic of the research of the settlement system in the recreational area ꢁas formed. The key indicators of the spatial analysis of recreational settlement are presented, and the features of their calculation and visualization by means of GIS are disclosed. The much attention ꢁas given to the problem points of the development of the Crimea settlement system. we substantiated the expediency of using recreation as an effective tool for settlement transformations. Recreational and settlement logic in the selection of promising “ points of groꢁth” of the peninsula settlement system ꢁas substantiated. we formed a map of the recreational potential of the resettlement field of the Eastern recreational area of the Crimea. Basing on this, ꢁe indicated the place and role of resort settlements in the settlement of the eastern Crimea and the zones of their influence. A map of transport accessibility by public transport of the existing recreational settlements of the Crimea is given, and the features of the calculation and visualization of this indicator by means of GIS are disclosed. Based on the analysis of the transport accessibility map of recreational settlements of the Crimea, ꢁe indicated promising boundaries of possible agglomeration processes in the direction “from recreation”. In conclusion, ꢁe give the classification of the zone of 60-minute transport accessibility of resort settlements of the Crimea, as the territories of the greatest intensification of interconnections of settlements.

The relevance of the study lies in the fact that in the management of the land cadastre great attention is paid to what modern technology is used to carry out cadastral work. To develop new GIS technology programs for the land cadastre is costly and time consuming. Currently, there are quite a few programs for GIS, both free of charge and paid. Comparing these programs, some paid systems far exceed free systems. The prices for these programs depend on the demand of users, the capabilities of the programs and many other aspects. The State Land Cadastre (SLC) is a complex land information system that solves various tasks in the field of land relations at all administrative and territorial levels (country, region, region, region, municipality). Processing of huge amounts of information about each land cadastral plot, contour of land, economic and administrative unit, their dynamics can only be done by modern computer systems and information technologies [1]. As an example, I considered the software package “TechnoCad-Express”. This program is in great demand among cadastral engineers, since it is very closely related to the Rosreestr program. For cadastral registration of boundaries, technical plans, a map of plans, land location schemes on the cadastral plan of territories and other similar documents created by this program, it is very convenient to work in Rosreestre. TechnoCad is convenient not only for the Rosreestr organization, it also fully meets the requirements of the Cadastral Chamber, i.e. for registration of rights of cadastral objects.

Based on remote mapping and field studies, a high variety of Quaternary aeolian relief and sediments has been established in Central Yakutia. Aeolian formations are found at all hypsometric levels and occupy at least 60 % of the region. Deflation-corrosion (ventifact plateaus, mushroom-shaped rock outcrops and pillars), deflation-accumulative (sand covers and dune massifs (ergs)) and accumulative (ice-reach-loess plateaus) types of aeolian relief are distinguished. The deflationary-accumulative forms of the dune relief are composed of hollow and cross-layered quartz sandy loams of the D’olkuminskaya Series, which formed from the end of the MIS 3 to the beginning of the Holocene (from 35 kyr to 10-12 kyr), as well as in the late Holocene. There are modern unvegetated dune massifs (tukulans) and Late Pleistocene ones, which are covered mainly by pine forests. Modern dune massifs are predominantly composed by small parabolic dunes, while ancient ones are represented by large U-shaped, spear-shaped and longitudinal dunes. The features of the aeolian relief are the orientation of elementary landforms in the southeast direction, the intersection of the river network, the frequent movement up the relief, and an increase in depth at higher hypsometric levels. The high activity of aeolian processes and the attenuation of fluvial activity during the Last Thermal Minimum and the Younger Dryas contributed to the destruction of low-order drainage net in vast territories, and led to the appearance of many drainless wind-blown depressions. In the Early Holocene, many of them, as a result of increased atmospheric precipitation, turned into lakes and bogs. The author concluded that the close interaction of aeolian, cryogenic, nival and fluvial processes during the Late Quaternary led to the appearance of some polygenetic facies - cryogenic-aeolian, niveo-aeolian, aeolian-fluvial, and aeolian-lacustrine. The structure and taxonomy of many of them remains poorly understood.

This article analyzes the development of the tourism industry accommodation sector in the Sakha Republic (Yakutia). One of the types of rapid development of the segment of the accommodation sector is the development of tourist bases in central Yakutia. The rich natural diversity of the landscapes of the republic contributes to the development of a new segment of the accommodation sector as tourist bases and recreation in nature. Tourist recreation centers are low-budget collective specialized accommodation facilities and important participants in the development of the domestic tourism market of the republic. Although, at this time, the number of tourist bases according to official statistics is not that large, but with the change in the market situation after the removal of the COVID-19 lockdown, there will be an increase in demand for family recreation in nature. The development of the tourist base segment also brings economic benefits such as new jobs in rural areas, income of the population, and contributes to the development of municipal infrastructure. The main problem is that most of the tourist bases do not have registration and exist illegally. It is revealed that the further development of tourist bases will be influenced by the regulation of tourism at the municipal and national levels.

The work is devoted to the study of temperature inversions on the territory of the Oymyakon Highland - the coldest region of the Northern Hemisphere. The studies were carried out in the ARCGIS software package using the Landsat 8 satellite infrared channels of the satellite images. The paper describes the basic patterns of the distribution of radiation temperature in the Oimyakon highlands, shows the seasonal dynamics of the correlation coefficient between the raster layers of the terrain and radiation temperature. The height distributions of the radiation temperature were constructed and their vertical gradients were found, which are in good agreement with the data of aerological observations, but have their uniqueness depending on the slope exposure. The high informativeness of remote sensing data in the study of inversion phenomena in mountainous and remote areas of the Earth with a very low density of meteorological stations is shown.
