Complexing of near-surface geophysical investigations within national historical-architectural sanctuary “Kamianets-Podilskyi”
SummaryIn this paper, the results of high-precision magnetic measurements, GPR investigations and ERT surveys that were conducted in the historical part of Kamyanets-Podilsky city are presented. For processing and interpretation, the raw data of geophysical field works that were collected during SEG Geoscience Field Camp in Ukraine 2017 were used. Kamyanets-Podilsky city is located within National Environmental Park “Podilski Tovtry”. This park contains unique remains of seashore reef that was placed parallel to the ancient coast. It is a Silurian reef that was built up by limestone which is full of different species of corals. There were six areas of investigation. In the paper they are mentioned under names: “Bastion”, “Inner yard of the castle”, “Northern yard of the castle”, “Cross”, “New caste” and “Next to the city hall”.
This paper is also giving explanations about archeological objects that possibly could cause the detected anomalies. According to interpretation, it can be underground tunnels, foundations of buildings or ancient fireplaces. Using these examples, the authors showed that this set of geophysical methods is an informative one to seek different kinds of archaeological objects in urban conditions. Presented results can be used for planning direct archaeological surveys or detailed geophysical observations.

Application of GIS technologies and remote sensing in precision farming
Authors I.O. Makedonska, V.I. Zatserkovnyi and L.V. TustanovskaSummaryThe development of agriculture determines the position of any state in the world economy and gives them significant advantages in solving food, raw material and energy problems in the domestic and world markets. Today, the preference is given to advanced technologies, namely, precision farming (crop management) systems based on the use of satellite and computer technolog. The research was conducted to reduce the unit cost of agricultural products and increase productivity per unit of expendable resources by remote sensing and GIS technologies.
On the basis of the obtained data maps of agricultural lands were constructed and the level of moisture content of the crop in different fields of the field was traced. The speed of harvesting is calculated and the optimal speed of transport is established, which prevents loss of their qualitative and quantitative properties. Given the high spectral reflectivity of plants, moisture content of barley was determined by color in the images of the spectra obtained in the IR ranges. Geoinformation systems trace the route, speed of technology, fuel level and other indicators, as well as calculated fuel consumption, engine power, speed of the car over different periods of time.

Methodology of time forecast of exogenous geological processes
Authors D. Kasiyanchuk, L. Shtohryn, N. Yazlovetska and M. LevitskaSummaryTaking into account dynamic of the natural conditions, it is necessary to approach the choice of factors of time analysis more precisely, since modern approaches do not provide high reliability of existing methods for their more detailed forecasting of exogenous geological processes (EGP). The task of presenting a new methodology for forecasting exogenous geological processes (in particular, landslide processes) with a clear gradation of the choice of factors for the long-term, medium-term, and short-term forecast, is based on previous studies of authors and proposed new factor characteristics in order to detail them. In particular, the conducted working out in detail concerns the statistical analysis by years, as well as by months within the year, using interdependent factors (precipitation, temperature), solar activity (Wolf number), seismicity, etc. on the example of the Carpathian region. Assuming that the laws of the dynamics of these natural factors do not change for a certain area over time, it is possible to estimate the probability of landslides in the future according to these data.

Authors M.V. Zhukova, V.I. Zatserkovnyy, P.I. Trofimenko and N.V. TrofimenkoSummaryThe article is analyzing conditions and features of using remote sensing of the Earth (RSE) in agriculture. Key and promising directions of using available information was identified after using GIS and RSE. The article reveals systematic problems that limit the use of remote sensing and its results: absence of unified technological standards, low level of data processing automation, absence of coordination between departments, users and data owners regarding the use of information. In order to provide access to satellite data, the establishment of distributed system for collection, storage and processing of RSE was proposed. In the context of land market evolvement in Ukraine, the article indicates the importance of implementation of the set of measures aimed to ensure the transparency of land related transactions and maximum accuracy of data in the agricultural sector, including through the organization of the function of the designated centers. For agricultural needs the main purpose of establishment of such centers is considered in supply of related individuals and legal entities with functional tools of RSE data use. Among the main tasks of the centers: provision of analytical, scientific, technical, referral, educational and methodical information, as well as the implementation of specific projects and provision of services in the agricultural sector.

Authors O.Ye. Petrokushyn, S.A. Vyzhva and I.M. BezrodnaSummaryThis paper presents the results of petrophysical studies of the sandstone collection, which were investigated by centrifuge method, correlation interactions of their petrophysical parameters and qualitative determination of the structure of the cavity space. The collection of sandstones is represented by 17 samples, selected from wells №. 100, 101 of the Runovschinskaya area (Dniprovsk-Donetsk basin, Ukraine), which belong to the depth range 529 — 890.3 m. According to the mineral structure samples are medium and coarse sandstones composed of quartz grains, feldspars and have a low content of mica minerals and carbonated residues.
The authors analyzed the changes of physical parameters of rocks-sandstones by centrifuge method. In particular, the coefficients of residual water and oil saturation, the velocity of elastic waves, the specific electrical resistance and the saturation parameter of samples at different speeds of the centrifuge were investigated. The authors have a qualitatively comparable structure of the cavernous space of the studied samples of sandstones, and the dependencies between the porosity parameter and the residual water saturation coefficient are established.
The obtained results give an idea of the structure of the void space of the selected collection of samples and the ability to estimate the amount of residual water in the samples. These data can be used to establish other petrophysical dependencies and to define petrophysical models.

Synergetic Use of Sentinel-1 and Sentinel-2 Data for Analysis of Urban Development and Green Spaces
Authors A.A. Kozlova, A.V. Khyzhniak, I.A. Piestova and A.A. AndreievSummaryIn the presented study a methodological framework to integrate Sentinel-1 and Sentinel-2 imagery for accurate mapping of urban development and amount of vegetation in urban green spaces by integrating the advantages of radar and optical imagery was proposed. It was tested on Kiev city area using Sentinel-2A level 2 multispectral image and two Sentinel 1A images (Level-1 SLC), forming an interferometric pair. For urban extant and development extraction from combined use of Sentintinel-1 and Sentinel-2A images existing verified methods were used. For urban vegetation quantity estimation using multispectral satellite imagery, a method based on LAI(NDVI) dependence was applied. As a result, five challenging classes of urban development were extracted. Obtained LAI map characterizes urban green spaces. Its values correspond to the amount of total green vegetation of all canopy layers including the understory This research demonstrates that synergetic use of Sentinel-1 SAR and Sentinel- 2 MSI data both for buildup areas extraction and for urban vegetation quantitative estimations is very promising for analysis of urban development and green spaces. The algorithm presented here will provide objective, reliable and operative information to urban planners and decision-makers.

Computation optimization for forward and inverse NMR T2 relaxometry task problem
Authors D.D. Byzov, S.V. Zhakov and L.A. MuravyevSummaryNMR relaxometry now is a powerful tool for detecting and distinguishing of reservoir fluids, such as free and bound water, oil. NMR data allows studying the types of fluids and their distribution in a deposit penetrated by the well. NMR can identify the intervals in which hydrocarbons are present and predict their recoverability. In this work, we aimed to optimize of calculating time for the integrals arising in the NMR forward and inversion problems. We propose Legendre polynomial expansion method for the modeling relaxation curves problem in the NMR relaxometry. This tool reduces significantly the computational complexity of the relaxation curve calculation, and hence it reduces the calculation time in comparison with numerical integration methods. Since we use an analytic expression for the integral, the calculation accuracy depends only on the integration error. The given approximation error is achieved due to the choice of the maximum degree of the polynomial at the stage of calculating the coefficients of the series of the Legendre polynomials.
