The COVID-19 outbreak has heavily influenced the way many businesses operate across all sectors linked to both changes in the consumer behavior, social-distancing restrictions and also the availability of resources and services (inc. public services) for businesses. These restrictions have influenced also the work of enterprises in the sector of bioeconomy � producers, processors and distributors of manufactured goods like food, clothing or home goods and other bio-based sectors both in the stages of primary production and processing and distribution. This study aims to assess the digitalisation process of the enterprises in the bioeconomy sector, the enterprise`s motivation for digitalisation and the impact of COVID-19 to the digitalisation of enterprises. It analyses the results of a survey carried out in Latvia in 2 phases � in 2020 and 2021 of entrepreneurs and employees of the enterprises working in the sector of bioeconomy, which allows to identify the digitalisation tools used by these enterprises and their motivation in moving towards the digital transformation.

The basis of the natural resource base of the resort and recreational sphere is made up of natural healing resources (mineral waters, mud, brine of lakes and estuaries). In the context of the introduction of the concept of sustainable development, special attention is paid to the assessment of natural conditions and resources, systematization and monitoring of data on natural healing resources of the country. The State Cadastre of natural healing resources is being developed to systematize data, knowledge and information about known mineral waters, therapeutic mud, etc. The organization of information about the geodata of cadastres, in accordance with modern international standards, involves the use of conceptual modeling and the creation of a catalog of geodata object classes. On the example of data on mineral waters, a comprehensive solution for collecting, analyzing and presenting information based on open source software - GIS technologies and object-relational database technologies is presented. Based on the list of information included in the Cadastre of natural healing resources, a Geodata Catalog was created, which is the basis for the physical design of the Cadastral geodatabase. The article discusses the features of the structure of the physical implementation and functioning of the automated geoinformation system of the geodatabase of the Cadastre of natural healing resources. It is shown that the capabilities of object-relational databases and GIS based on open technologies can be used for input, analysis, statistical processing of a significant amount of information and its visualization.

The research is part of the �Design of an intelligent system to forecast landslides' processes and their influence on the roads' technical and operational characteristics� project financed by the Ministry of Education and Science of the Republic of Kazakhstan by AP09260066 program. The research goal is in surveying deformed parts of �Almaty-Cosmostation� automobile road nearby critical slopes to identify in the next phases the causes of pavement degradation and formulate then the recommendation to prevent such degeneration. This site was chosen due to the extreme danger associated with the possible closure of the river flowing through the gorges along the road under study due to a landslide slope. This can lead to a change in the riverbed, the formation of a strong water flow, which will create a danger to the population, will lead to significant material damage. Main results. Within the framework of this project, new knowledge will be gained in the theory of forecasting the occurrence of landslide processes and their impact on the technical and economic indicators of highways, which undoubtedly has applied significance and contributes to the widespread introduction of intelligent systems for forecasting and making industry decisions. Detailed engineering and geological research of deformed parts of �Almaty-Cosmostation� automobile road nearby critical slopes are provided. The article results with the field researches to formulate causes of deterioration of the road pavement and formation of longitudinal and transversal cracks on it. To develop intelligent models for predicting landslide processes and their impact on the state of the road, the following types of work were carried out: georadar sounding method; Earth remote sensing methods; ground-satellite geodesy method; modeling and training of intelligent systems. Conclusions: The surface smoothness of the road pavement is partly below the minimum permissible level. The causes of the �irregular� (unusual) transversal cracks should be associated with slides of the rock masses and water falling from the rock slopes. Suggested causes of the grading�s slide slopes� erosion are the faint provision of surface drainage for the road pavement. The unevenness of the pavement on a micro level is connected to the uncompacted enough asphaltic concrete pavement and other pavement�s layers. The field researches� results will be used for training and testing of intellectual models.

The structural analysis of the civil infrastructure is vital in order to track the evolution of degradation in time, to prevent disasters, but also to document and conserve the sites of cultural heritage. This paper review�s the workflow on the acquisition of point clouds to Terrestrial Laser Scanner (TLS) with those collected by photogrammetric 3D models based on images captured by an unmanned aerial vehicle (UAV), analyzing the data sets on two diferent type of bridges located in western Romania. The obtained data can serve a wide range of applications and supports different studies, also providing new digital tools that help tracking the degradation in time, reducing the technical limitations in the cultural heritage preservation, and exploring alternative ways for shaping future steps associated with saftey inspection. Depending on the objective, the use of such integrated technologies brings a significant contribution as a support tool for decision making. Due to the geometric complexity of the structure, the accuracy of measurements was limited by the resolution of sensors (remote-sensing data) and areas without light, hard to reach by lens. The comparative analysis of the two techniques shows that both methods produced similar results with high precision but also presented disadvantages in terms of data associated with spatial features.

In 2004, a digital terrain model (DTM) was created in Serbia. It was obtained by vectorizing isohypses on topographic maps with a scale of 1: 25000. The resolution of the digital model of Serbia is 30 m, and the vertical accuracy, as the authors claim, is 10 m. From December 2021, the global model FABDEM (Forest And Buildings removed Copernicus DEM) is available to the public. It was created based on the data of the Copernicus GLO30 model so that data on forests and buildings were removed from it. Important features of the global model are its horizontal resolution of 30 m and vertical accuracy of less than 5 m. This paper aims to assess the vertical accuracy of the global FABDEM model and analyze the differences between the global FABDEM and DTM in the territory of the Republic of Serbia. Vertical accuracy and analysis of the two models were assessed by comparing the heights derived from FABDEM and DTM with the heights of the independent set of points of the gravimetric survey of Serbia (GSS). The heights of the GSS points were determined using classical geodetic methods, and they are relatively uniformly distributed on the territory of the Republic of Serbia. A short description of mentioned comparison is presented in this paper. Statistical analysis results that compare terrestrial heights with heights derived from DTMs show minor differences between the two data sets.

BIM (Building Information Modeling) allows the use of a virtual building model throughout the whole life cycle of the building. It is a parametric object-oriented 3D data model of a building, which contains information about structures, elements, and their parameters. The combination of the BIM model with detailed data on the as-built geometry of the building enables an effective geometry check of the structural elements, which leads to in-time intervention in the building process if needed. The requirement of effective data collection is fulfilled by the methods of 3D laser scanning and closerange photogrammetry. The paper describes the possibility of checking the geometry of buildings by comparing the design of a building (as-planned model), derived from a BIM model in the IFC exchange format, to point clouds (as-built model). The proposed approach uses extraction of the geometric parameters of the structural elements from IFC; afterward, segments the point cloud and creates the as-built model; and in the last step, the as-planned and the as-build models are compared. The advantages of the proposed approach over conventional geometry check methods are also discussed.

The significant development of single-board computers today can create many different threats to information security. These devices open up new opportunities for attackers, as they allow them to find new ways to carry out attacks. Since SBCs are often small in physical size, but have the processing power to run full Linux distributions, combined with a variety of different external interfaces, this allows you to create devices that can listen to sound, photo and video recording, and intercept network traffic. Methods and ways to prevent such violations of information security have not been fully compiled. The use of single-board computers as a tool for violating information security has already been carried out in real conditions. This confirms the urgency of the problem. This is due to the fact that these devices have increased energy efficiency, universal software, low cost, as well as ways to work in difficult environmental conditions. Such characteristics make it easier to penetrate into controlled areas, negotiation zones, and the like in order to violate the information security of workplaces. For example, a board with a wireless controller connected to an external power source is capable of intercepting network traffic, and a single-board computer with interfaces for connecting external devices, disguised as some other household item, is capable of taking photos and videos. One of the key methods of combating these violations is understanding the principles of operation and use of single-board computers by intruders in illegal actions, the purpose of which is to violate information security.

The purpose of the paper is to clarify the formation mechanism of the devastating flood in the town of Svilengrad, in the Republic of Bulgaria, in June 2012. The systemic approach is used to analyze flood formation mechanisms and improve under-standing of the complex interactions between the factors determining the formation and manifestation of floods. The spatial analysis method takes a central place in the examination of the flood formation mechanisms, using GIS as a tool for analysis. Hydraulic model for the 9 km long river section has been adapted and for this purpose a Digital Elevation Model (DEM) has been generated. Taking into account the specifics of the riverbed and the results of previous research on the design and investment process in the river area, a one-dimensional model is applied (Hydrologic Engineering Center - River Analysis System, version 5.0.3, developed by the US Corps of Military Engineers) to determine the flooded areas during the flood. The main result of the study is the clarified flood formation mechanism in the town of Svilengrad, which occurred on 06.02.2012. Information on the flood formation mechanism is of particular importance for the institutions responsible for flood risk assessment and management. It will allow them to formulate adequate measures for reduction of the floods risk in this part of the Maritsa River. The popularization of the results of the survey among the population of Svilengrad is a prerequisite for raising its awareness and preparedness for a more adequate response in case of a new disaster/flood.

Today, point clouds are becoming an increasingly common digital representation of realworld objects. However, the raw point clouds obtained by terrestrial laser scanning (or other methods, e. g., photogrammetry or low-cost sensors) are often noisy with many outliers. Thus, it is necessary to remove the noise and outliers from the point clouds before further processing while preserving the elements of the measured objects in high detail. Moreover, in the case of model creation from point clouds using basic geometric shapes (e.g., planes, spheres, cylinders, etc.), one of the most important processing steps is the segmentation of these shapes. Therefore, filtration of unrelated parts of the point cloud can increase the efficiency of processing. In this paper, two algorithms for point cloud filtration are developed, which can be performed based on the local point density and the local normal variation in the surrounding of the selected point. The algorithms were implemented as a standalone application in MATLAB software. The paper's final part describes the experimental testing of the proposed algorithms on several point clouds with various densities, complexity, and different levels of noise and outliers.

However, the raw point clouds obtained by terrestrial laser scanning (or other methods, e. g., photogrammetry or low-cost sensors) are often noisy with many outliers.

A thematic map contains a spatial database that allows the user to add new information to that database. The ability to combine a variety of datasets in a variety of ways makes any GIS a useful tool for almost any field of knowledge. From routinely performing work-related tasks to scientifically exploring the complexity of our world, GIS offers people the geographic advantage of becoming more productive, more aware, and more receptive to the planet Earth. A GIS can be defined as a system designed to capture, store, manipulate, analyze, and visualize geographically referenced data. Thematic maps are the result of spatial analysis sets made in GIS programs. Spatial analysis includes the techniques by which the relationships between entities are studied, from a topological, geometric or geographical point of view. Depending on the requirements and the existing data in the database, the maps may have different thematic results: demographic, social, economic, analysis, prediction, evaluation, anticipation maps, etc., depending on what you want to do analyze.
