Abstract This article concerns the use of remote sensing methods to assess the potential of tourism and recreation of lakes by using unmanned aerial vehicles as a tool that offers new measurement possibilities in such difficult areas to research as river and lake systems. For the purpose of the study, air surveys over three lakes used for tourism and recreation purposes were planned and carried out. These were the following lakes: Swarzędzkie, Wolsztyńskie and Zbąszyńskie located in western Poland. The photos were taken with a RGB and a multispectral cameras. On the basis of calculated orthophotomaps and digital surface models, anthropogenic and natural values were assessed. The examples of the research show the versatile possibilities of using drones dependent on the type sensor used. Remote sensing performed from the deck of an unmanned aircraft is widely used in the study of lakes and is an alternative to existing land and water research methods.

Unmanned aerial vehicles (UAVs) or drones have revolutionized scientific research in multiple fields. Drones provide us multiple advantages over conventional geological mapping or high-altitude remote sensing methods, in which they allow us to acquire data more rapidly of inaccessible or risky outcrops, and can connect the spatial scale gap in mapping between manual field techniques and airborne, high-altitude remote sensing methods. Despite the decreased cost and technological developments of platforms, sensors and software, the use of drones for geological mapping in Mongolia has not yet been utilized. In this study, we present using of drone in two areas: the Chandman area in which eclogite is exposed and the Naran massif of the Khantaishir ophiolite in the Altai area. Drone yields images with high resolution that is reliable to use and reveals that it is possible to make better formulation of geological mapping. Our suggestion is that (1) Mongolian geoscientists are encouraged to add drones to their geologic toolboxes and (2) drone could open new advance of geological mapping in Mongolia in which geological map will be created in more effective and more detailed way combined with conventional geological survey on ground.

A green plantations monitoring is an important work, which includes regular monitoring of urban landscapes in order to identify negative timely changes and to prepare the informed decisions to prevent their degradation. In modern conditions, it is advisable to improve this process by using remote sensing methods, the materials of which are processed in geographic information systems, which allows to establish an automated monitoring system of green areas. The purpose of the study is to substantiate the feasibility of geo-information monitoring of urban landscapes using remote sensing methods, including unmanned aerial vehicles. To achieve this goal, structural schemes of the monitoring system organization to get the information about green plantation conditions are proposed, together with the possibilities of using orthophotoplans, which are obtained by remote sensing methods for the needs of regular study of urban landscapes. Repeated remote monitoring of the green plantations condition allows to detect the timely changes that have occurred with tree and shrub vegetation over a period in an automated mode. The use of remote sensing materials in this case can be used as a documentary basis to justify the implementation of measures for landscaping. Due to the expensive cost of high-resolution materials, we recommend to use in the process of urban landscape monitoring proposed approach with regular surveys of unmanned aerial vehicles for greenery facilities. On the basis of the conducted researches the multifunctional structure of the green plantings monitoring system is offered and carrying out of digital transformation of monitoring process of urban landscapes condition is recommended. These studies indicate the feasibility of introducing regular automated monitoring of green areas with the involvement of remote sensing methods, including using unmanned aerial vehicles.

Damage caused by flood events is expected to increase in the coming decades driven by increased land use pressures and climate change impacts. The insurance sector needs accurate and efficient loss adjustment methodologies for flood events. These can include remote sensing approaches that enable the rapid estimation of (i) damage caused to property as well as (ii) the number of affected properties. Approaches based on traditional remote sensing methods have limitations associated with low-cloud cover presence, oblique viewing angles, and the resolution of the geomatic products obtained. Unmanned aerial vehicles (UAVs) are emerging as a potential tool for post-event assessment and provide a means of overcoming the limitations listed above. This paper presents a UAV-based loss-adjustment framework for the estimation of direct tangible losses to residential properties affected by flooding. For that purpose, features indicating damage to property were mapped from UAV imagery collected after the Desmond storm (5 and 6 December 2015) over Cockermouth (Cumbria, UK). Results showed that the proposed framework provided an accuracy of 84% in the detection of direct tangible losses compared with on-the-ground household-by-household assessment approaches. Results also demonstrated the importance of pluvial and, from eye witness reports, lateral flow flooding, with a total of 168 properties identified as flooded falling outside the fluvial flood extent. The direct tangible losses associated with these additional properties amounted to as high as £3.6 million. The damage-reducing benefits of resistance measures were also calculated and amounted to around £4 million. Differences in direct tangible losses estimated using the proposed UAV approach and the more classic loss-adjustment methods relying on the fluvial flood extent was around £1 million—the UAV approach providing the higher estimate. Overall, the study showed that the proposed UAV approach could make a significant contribution to improving the estimation of the costs associated with urban flooding, and responses to flooding events, at national and international levels.

Беспилотные воздушные суда и беспилотные авиационные системы становятся частью повседневной жизни, в том числе в деятельности органов и учреждений уголовно-исполнительной системы. В статье исследован исторический аспект появления беспилотных воздушных судов в России и зарубежных странах, необходимость, типовые задачи и особенности правового регулирования использования беспилотных воздушных судов в уголовно-исполнительной системе. Однако ряд вопросов до настоящего времени является предметом дискуссии и требуют правового регулирования. Современные технологии позволяют оснастить беспилотные воздушные суда различными приборами, придающими им дополнительные функциональные характеристики: приборами видео- и фотофиксации, тепловизором, громкоговорителем, оружием. В зарубежных странах сложилась разная практика регулирования: от разрешения использования беспилотных воздушных судов с оружием в правоохранительной деятельности и уголовно-исполнительной системе (США, Великобритания и др.) до протестов гражданского общества и требований законодательного запрещения использования беспилотных воздушных судов, способных причинить вред человеку. Не решены вопросы в части регулирования порядка сбора, обработки, передачи и хранения (в том числе длительности хранения) информации, полученной в ходе видео- и фотофиксации, включая передачу информации, содержащей персональные данные гражданина, в частности, его изображение. Обсуждается вопрос о соблюдении прав человека и гражданина, в том числе осужденного, при получении и использовании информации, полученной при помощи беспилотных воздушных судов в деятельности органов и учреждений уголовно-исполнительной системы. Требуется внесение изменений в процессуальное законодательство в части регулирования использования данных, полученных при помощи беспилотных воздушных судов, как доказательств, а также в целом их юридическое значение в административном, уголовном, гражданском (арбитражном) процессе. Необходимо урегулирование вопросов ответственности сотрудников уголовно-исполнительной системы, которые могут превысить полномочия с помощью использования беспилотных воздушных судов. В рамках Национальной технологической инициативы происходит активное развитие рынка АэроНет, поэтому беспилотные воздушные суда в деятельности уголовно-исполнительной системы могут стать частью этого рынка. Unmanned aerial vehicles and unmanned aircraft systems are becoming part of everyday life, including in the activities of bodies and institutions of the penal system. The article examines the historical aspect of the appearance of unmanned aerial vehicles in Russia and foreign countries, the need, typical tasks and features of the legal regulation of the use of unmanned aerial vehicles in the penal system. However, a number of issues are still the subject of discussion and require legal regulation. Modern technologies make it possible to equip unmanned aerial vehicles with various functional characteristics, ranging from video and photo capture, the availability of a thermal imager, a loudspeaker, to weapons. In different countries, different regulatory practices have developed: from allowing unmanned aerial vehicles with weapons in law enforcement and the penal system (USA, UK, etc.) to civil society protests and the requirements of the legislative prohibition on the use of unmanned aircraft that can cause harm to humans. Unresolved issues regarding the regulation of the procedure for collecting, processing, transferring and storing (including the duration of storage) of information obtained during video and photo recording, including the transmission of information containing personal data of a citizen, including its image. The issue of observing the human rights of a citizen, including a convict, is discussed when receiving and using information received by unmanned aerial vehicles in the activities of bodies and institutions of the penal system. Amendments to the procedural legislation are required in terms of regulating the use of data obtained by unmanned aerial vehicles as evidence, as well as in general their legal significance in the administrative, criminal, civil (arbitration) process. It is necessary to resolve the issues of responsibility of employees of the penitentiary system, which may exceed their authority through the use of unmanned aerial vehicles. As part of the National Technological Initiative, the AeroNet market is actively developing, therefore unmanned aerial vehicles in the activities of the penitentiary system can become part of this market.

Practical Accuracy

Abstract. Unmanned aerial vehicles (UAVs) equipped with image sensors, which have been widely used in various fields such as construction, agriculture, and disaster management, can obtain images at the millimeter to decimeter scale. Useful tools that produce realistic surface models using 3D reconstruction software based on computer vision technologies are generally used to produce datasets from acquired images using UAVs. However, it is difficult to obtain the feature points from surfaces with limited texture, such as new asphalt or concrete, or detect the ground in areas such as forests, which are commonly concealed by vegetation. A promising method to address such issues is the use of UAV-equipped laser scanners. Recently, low and high performance products that use direct georeferencing devices integrated with laser scanners have been available. Moreover, there have been numerous reports regarding the various applications of UAVs equipped with laser scanners; however, these reports only discuss UAVs as measuring devices. Therefore, to understand the functioning of UAVs equipped with laser scanners, we investigated the theoretical accuracy of the survey grade laser scanner unit from the viewpoint of photogrammetry. We evaluated the performance of the VUX-1HA laser scanner equipped on a Skymatix X-LS1 UAV at a construction site. We presented the theoretical values obtained using the observation equations and results of the accuracy aspects of the acquired data in terms of height.

Vast Territory

The vast territory of Russia, occupied by agricultural lands, is difficult to control due to the lack of an undeveloped network of operational monitoring points, ground stations, including meteorological stations, lack of aviation support due to the high cost of maintaining staff, etc. In addition, due to various types of natural processes, there is a constant change in the boundaries of acreage, soil characteristics and vegetation conditions in different fields and from site to site. Abroad, the above mentioned problems are successfully solved due to the application of remote sensing data (RSD) of the Earth, obtained with the help of unmanned aerial vehicles (UAVs). The proceedings, obtained (UAV), can help both to solve complex tasks of managing agricultural territories, and in highly specialized areas.
