Abstract:

This article discusses the process of creating a digital forest model based on remote sensing data, three-dimensional modeling, and forest inventory data. Remote sensing data of the Earth provide a fundamental tool for integrating subsequent objects into a digital forest model, enabling the creation of an accurate digital model of a selected forest quarter by using forest inventory data in educational and experimental forestry, and providing a valuable and extensive database of forest characteristics. The formalization and compilation of technologies for connecting forest inventory databases and remote sensing data with the construction of three-dimensional tree models for a dynamic display of changes in forests provide an additional source of data for obtaining new knowledge. The quality of forest resource management can be improved by obtaining the most accurate details of the current state of forests. Using machine learning and regression analysis methods as part of a digital model, it is possible to visually assess the course of planting growth, changes in species composition, and other morphological characteristics of forests. The goal of digital, interactive forest modeling is to create virtual simulations of the future status of forests using a combination of predictive forest inventory models and machine learning technology. The research findings provide a basic idea and technique for developing local digital forest models based on remote sensing and data integration technologies.

Abstract:

Forests are crucial in supporting biodiversity and providing ecosystem services. Understanding forest biodiversity dynamics under different management strategies and climate change scenarios is essential for effective conservation and management. This paper introduces the Forest Biodiversity Dynamics Prototype Digital Twin (pDT), integrating forest and biodiversity models to predict the effects of management options on forest ecosystems. The primary objective is to identify optimal management strategies that promote biodiversity, focusing on conservation and adaptation to different climate conditions. We start with the case of Finnish forests and bird species and plan to expand to include more European countries and a variety of species as the pDT is further developed.

Abstract:

Abstract The question of who participates in making forest environments usually refers to human stakeholders. Yet forests are constituted through the participation of many other entities. At the same time, digital technologies are increasingly used in participatory projects to measure and monitor forest environments globally. However, such participatory initiatives are often limited to human involvement and overlook how more-than-human entities and relations shape digital and forest processes. To disrupt conventional anthropocentric understandings of participation, this text travels through three different processes of “unsettling” to show how more-than-human entities and relations disrupt, rework, and transform digital participation in and with forests. First, forest organisms as bioindicators signal environmental changes and contribute to the formation and operation of digital sensing technologies. Second, speculative blockchain infrastructures and decision-making algorithms raise questions about whether and how forests can own themselves. Third, Amerindian cosmologies redistribute subjectivities to change how digital technologies identify and monitor forests within Indigenous territories. Each of these examples shows how more-than-human participation can rework participatory processes and digital practices in forests. In a time when forests are rapidly disappearing, an unsettled and transformed understanding of participation that involves the world-making practices of more-than-human entities and relations can offer more pluralistic and expansive forest inhabitations and futures.

Abstract:

The article analyzes measures to improve the effectiveness of management of forest protection from fires on the basis of information technology. The purpose of this article is to review and analyze the existing system of management of forest protection from fires, identifying the main management problems and forming recommendations to improve the existing system on the basis of digital technology. The relevance of the study lies in the fact that in recent years there has been a large number of forest fires, which brings irreparable damage to the Russian economy, so the question of the effectiveness of today's forest fire prevention system in our country is urgent. Innovative tools to improve the fight against forest fires are digital technologies. As part of the study of measures to improve the effectiveness of forest fire protection management clarified the conceptual apparatus, considered the concept of "digital technology", "forest fire". Based on the analysis of forest fire management, measures based on digital technology, which will improve the fire situation in the territory of forestry in the Russian Federation. Fighting forest fires is a dangerous job, which requires instant decisions based on immediately available information. The main digital tools used for fire protection are drones, laser scanning remote sensing of forests. The use of these tools will make it possible to quickly and smoothly determine the onset of forest fires, their area and determine on this basis the activities of fire departments and forestry organizations sequence of actions to eliminate forest fires. The more accurate real-time data firefighters have, such as fire location and condition, the location of hazards, and the number of forests covered by fire, the greater the probability of saving forests and the animals that live in their territory, ensuring the safety of firefighters and limiting fire damage. Consequently, digital technology, when fighting a forest fire, is the main and most important tool, and its implementation will reduce the risk of fire and damage from it.

Abstract:

Abstract Mangroves are a forest ecosystem tolerant to salt (halophytic) and influenced by sea tides. Mangrove forests are producers of ecosystem services that all living things need. The use of remote sensing can be used to identify mangrove forests in large areas in a short time. Sentinel-1 is a satellite product widely used to monitor land cover, including mangrove forests. The research objective was to identify mangrove forests in the Medan Belawan District using Sentinel-1 satellite imagery. Land cover classification in digital images was done using supervised classification with the maximum likelihood and random forest method. The results showed that random forest methods are more accurate than the maximum likelihood of identifying mangrove forests in Medan Belawan. The kappa accuracy value of the digital satellite image classification using the random forest method is 85.09%, and the maximum likelihood method is 77.4%. Based on the random forest method, the mangrove forest area is 1,325.81 hectares or 43.64% of the Belawan District area.

Abstract:

This study explores the multi-dimensional relationships between technology, fiscal decentralization, and forest resource efficiency, and the pivotal role played by the digital economy as a mediator in 2002–2020. First, this study evaluates the Chinese provinces’ forest resource efficiency using multi-dimensional inputs and outputs of forest sectors. Further, we use two sorts of technology: high-technology expenditure and forest technology education. Fiscal decentralization in terms of local government expenditure on forest resources makes the study innovative and richer in analysis. A SBM-DEA analysis showed that the Anhui, Beijing, Jiangsu, Shanghai, and Zhejiang provinces have the highest efficiency scores, implying very efficient forest resource management. Subsequently, the robust econometric estimator Driscoll and Kraay is applied. The study’s findings disclose that both dimensions of technology increase the Chinese provinces’ forest resource efficiency through technological expenditure and forest technology education. Fiscal decentralization towards forest resource management expenditure increases the efficiency of forests. Urbanization and economic development reduce the efficiency of forests. The digital economy can effectively help to improve the efficiency of forest resources. The presence of moderating effects reveals that the influence of the digital economy on forest resource efficiency is positive when it is coupled with economic development, fiscal decentralization, technology, and urbanization.

Abstract:

In the policy arena of the rapid development of China’s digital village, understanding how internet use enhances the happiness of forest farmers’ families holds theoretical and practical significance for promoting the protection of the ecological environment and the sustainable development of forests. This study utilizes survey data from 2023 on forest farmers in ecologically fragile ethnic areas in China. Based on sustainability, a five-dimensional evaluation index system for the happiness of forest farmers’ families has been constructed. First, the CRITIC-TOPSIS model is employed to calculate the happiness scores of forest farming households. Subsequently, the Tobit model and the mediation effect model are applied to examine and analyze the influencing factors and mechanisms of internet usage on the happiness of forest farmers’ families. The study finds that, first, an increase of one unit in terms of internet use is associated with a 0.031-unit increase in the happiness of forest farmers’ families, and that education, social perception, and policy perception all have a positive effect on the happiness of forest farmers’ families. Second, the mechanism of action suggests that internet use significantly increases forest farmers’ families’ happiness through subjective class identity. Third, further heterogeneity analyses revealed that internet use contributed to the happiness of forest farmers’ families in the male group, the low human capital group, and the group with an ecological forest ranger in the family. Therefore, it is necessary to strengthen the construction of digital rural infrastructure and develop new models such as digital forestry; cultivate and introduce specialized digital talents in rural areas and enhance the digital literacy of forestry farmers; and assist forestry farmers in establishing class identity concepts and social values conducive to the sustainable development of forests and implement ecological values in production practices, thereby improving the happiness of forest farmers’ families.

Abstract:

Reliable estimation of the forest soil nitrogen spatial distribution is necessary for effective forest ecosystem management. This study aimed to develop high-resolution digital soil maps of forest soil nitrogen across South Korea using three powerful machine learning methods to better understand the spatial variations of forest soil nitrogen and its environmental drivers. To achieve this, the study used national-level forest soil nitrogen data and environmental data to construct various geographic and environmental variables including geological, topographic, and vegetation factors for digital soil mapping. The results show that of the machine learning methods, the random forest model had the best performance at predicting total soil nitrogen in the A and B horizons, closely followed by the extreme gradient-boosting model. The most critical predictors were found to be geographic variables, quantitatively confirming the significant role of spatial autocorrelation in predicting soil nitrogen. The digital soil maps revealed that areas with high elevation, concave slopes, and deciduous forests had high nitrogen contents. This finding highlights the potential usefulness of digital soil maps in supporting forest management decision-making and identifying the environmental drivers of forest soil nitrogen distribution.

Abstract:

Canfor's Englewood Division acquired a GIS two years age. Within this period, we have developed the framework necessary to digitally manage our 200 000 hectare Tree Farm License. This paper focuses mainly on the role GIS played in our Management and Working Plan. The plan is produced every five years to document and justify our forest land management techniques. It addresses issues of current and long-term wood supply; the 200 year horizon, silviculture regimes, and habitat requirements. GIS was used in conjunction with a forest estate model to test numerous management scenarios. Important issues included the decision to load 'dirty' data, the acquisition of contour data, net-working data, raster/vector processing, restructuring for feature codes, and becoming a 'beta' test site for GIS software. In addition, we discuss our objectives for 1991 relating to training, wildlife habitat, ambrosia control, a cruise prediction system, coordinate geometry and other goals.

Abstract:

This PhD ‘by practice’ aims to understand ways in which painting confronts the experience of living in a digital age. The objective was to produce a body of paintings at a time of a shifting visual regime in order to reflect on the ways technology affects our temporal and historical relationship with the environment of the landscape and its inhabitants. Painting was used in the study to develop ‘felt knowledge’ – a form of artistic knowledge acquired through sensory and emotional perception.1 Using ‘felt knowledge’, I develop an analogy between the Internet surfer and a particular notion of the hunter in nature. The locus of the hunt is a liminal space that provides opportunities where various forms of natural and unnatural adventures can arise. The forest is seen as a place where one might experience a terrifying or enchanting loss of normal boundaries or understanding of the rules of engagement. The study uses a number of critical perspectives to explore questions of the closing temporal gap between events, analysis, production and absorption. A key concept is that of viewing nature as ‘Otherness’. The essential core of Otherness is inevitably nameless. Merleau-Ponty (2002), suggested that this experience comes about through a momentary loss of self-consciousness leading us to encounter otherness directly and with astonishment: “ In order to see the world and grasp it as paradoxical, we must break with our familiar acceptance of it and, also, from the fact that from this break we can learn nothing but the unmotivated upsurge of the world.” 2 Imagination is not possible without that radical otherness; it is this oddness, this uncertainty that forms the direction of my studio practice and my written reflections on where and how we live today. McLuhan’s work and his thoughts on the impact of media, particularly technological and digital media, contribute to my current concerns about the place and use of painting today. McLuhan suggests we snap out of our numbness, which is induced by the over dominance of a particular media or pattern. One possible solution to the anaesthetic effect of a particular medium is to use another medium that has an antidote effect. As a PhD by practice, the making of paintings has been the dominant mode of enquiry, with the accompanying text acting as a supporting device. In the written text, I reflect on the problematic relationship between painting and writing, following Matisse’s articulation of the difficulties and often-unnecessary demands made by writing. My approach to painting and the relationship that writing has to it is an explication of my methodology, which recognises the need to maintain an iterative movement between proximity/immersion and distance/reflection. The methods both acknowledge the need to make practical knowledge explicit, and a everse movement whereby the painterly procedure becomes a way to physically test the possibilities and limits of language in articulating this. Against exaggerated claims of the death of painting in the face of technological and other developments, the proposition of this thesis is that painting’s continuation and relevance at this historical moment is determined in part by a unwillingness of painters themselves to see it extinguished; and that furthermore, the practice of painting utilizes its marginalized position to its advantage. My contribution to knowledge lies in the consideration, fused into the paintings, of how the transformation of paint can convey an awareness of the affects of the closing temporal gap between events, analysis, production and absorption and the demonstration and articulation of how painting’s ‘moribund’ position has itself become its ability to communicate effectively from the margins.

Abstract:

Ground based forest inventory surveys can provide highly accurate measurements of tree and stand characteristics, but are time-consuming and costly, and therefore typically limited to number of sample plots. Estimating tree and stand characteristics from digitised aerial photographs can provide measurements from the whole stand, but is less accurate. The goal of this study was to evaluate the application of scanned, stereo aerial photography and digital photogrammetry in combination with tree crown delineation techniques to measure tree and stand characteristics in two sites in Scotland, Rosarie and Leanachan forests. Existing medium-resolution scanned images of true colour aerial photographs (1:10,000) were used to derive Digital Elevation Models (DEMs) of the forest canopy and digital orthophotographs. Tree crown delineation techniques were used on the derived digital orthophotographs and tree crown measurements including crown area and coordinates of each crown were derived. The DEMs in combination with Digital Terrain Models (DTMs) derived from digital contour maps, were used for the estimation of tree and stand heights. Equations derived from regression analysis of individual tree measurements on the ground, and the orthophotographs from Rosarie forest, were used for the estimation of tree and stand characteristics of both sites. For Rosarie forest the estimations of stand top height, basal area, stand volume stand biomass and stand density (~23.7%) were similar with the ground measured stand characteristics (±10%), where as for Leanachan forest the estimations were less accurate due to the non-optimum illumination conditions during the acquisition of the aerial photographs. The level of accuracy achieved in this study is adequate for measuring tree and stand characteristics, if the acquisition conditions of aerial photographs are optimal. Higher level of accuracy may be possible, but requires more accurate DTMs, possibly derived using active airborne remote sensing sensors.

Thesis (MSc)--Stellenbosch University, 2000. ENGLISH ABSTRACT: The aim of the study was to extract elevation information (such as tree height) from stereo satellite imagery (IRS-I C), to scrutinise the performance of the DTM (Digital Terrain Model) tools as provided by the LH (LeicalHelava) Systems' softcopy system, and subsequently to perform a feasibility study on the application of a practically viable forest inventory design. A softcopy photogrammetry workstation (LH Systems DPW 770), IRS-I C stereo panchromatic satellite imagery, and digital aerial photography at a scale of 1:30000 (scanned at 15 micrometers) was used. The study was conducted over various sites in the Sabie area (province of Mpumalanga) in South Africa, where extensive man made forests with pine and eucalypts are to be found. The extraction of stand parameters such as tree height was performed manually, semi-automatically, and automatically. In addition, the compartment area was determined using a GIS tool. The Digital Surface Models (DSM), representing the canopy structure of the stands, was extracted from the IRS-I C imagery and validated through a comparison of the resulting contours with the corresponding contours generated by aerial photogrammetric methods. Due to the coarse spatial resolution of the IRS-IC imagery (5m) and the suboptimal BIH (BaselHeight) ratio (0.57), only objects featuring a height exceeding 20m could be manually measured with confidence. Furthermore, only the edges of the compartments proved to be suitable for the determination of tree heights (i.e. with a sufficiently large parallax difference and image contrast). The manual determination of tree heights in the IRS-I C imagery yielded accuracies of about 95% compared to the height values of the aerial photographs and the ground data. The application of image enhancement techniques had severe effects on the accuracy of the IRS-IC stereo model, resulting in deviations of about -57m from the 'true' value. It was observed that image matching was only a problem where features changed their appearance (e.g. clearfelled or burnt areas) during the acquisition period of the stereo pair of the satellite imagery. LH Systems' Adaptive Automatic Terrain Extraction (AATE) tool performed very well for the creation of digital terrain and surface models when using digital aerial photography with a high scanning rate. In contrast, the automatic creation of canopy surface models from various forest compartments did not yield any useful results when applied to IRS-l C imagery. AATE could not model the canopy structure properly. The coarse spatial resolution of the satellite imagery in conjunction with the sparse post spacing (20m) and matching errors are most likely to be responsible for this poor performance. Two-phase sampling and the Hugershoff method were chosen for automatically derived height values to be evaluated for possible application in forest inventory. Unfortunately, neither for the determination of the regression estimator for the first method, nor for the calculation of timber volume after application of the Hugershoff method could any useful result be obtained. This is mostly due to the fact that image matching errors and blunders (resulting in tree heights of -885m) were not properly accounted for in the terrain extraction software. However, the outcomes for the manual measurement of tree heights performed on the satellite imagery show that under optimal conditions accuracies can be achieved similar to those for the height determination in small scale aerial photographs, but at lower cost. The obtained height values can then be used for the calculation of timber volume according to Eichhorn's law.

'n Sagtekopie fotogrammetriese werkstasie (LH Systems DPW 770), IRS-I C stereo panchromatiese satellietwaarneming en digitale lugfotografie is gebruik. Die studie is uitgevoer oor verskeie areas in die Sabie omgewing (Mpumalanga, Suid-Afrika), waar daar ekstensiewe mensgemaakte woude voorkom met denne en Eucalyptus soorte. Die ekstraksie van opstandparameters soos boomhoogte is uitgevoer met die hand, as ook met semi-outomatiese en outomatiese metodes. Die digitale oppervlakmodelle (wat die kroondakstrukture van die opstande voorstel) was vanaf die IRS-I C beelde onttrek en gevalideer deur vergelyking van die resulterende kontoere met die korresponderende kontoere wat deur lugfotogrammetriese metodes gegenereer is. As gevolg van die growwe ruimtelike resolusie van die IRS-IC waarneming (Sm) en die suboptimale BIH verhouding (0.57) kan slegs voorwerpe met 'n hoogte van meer as 20m met vertroue met die hand gemeet word. Slegs die rande van die vakke is bruikbaar vir die berekening van boomhoogtes (d.w. s. met 'n voldoende paralaksverskil en 'n sterk beeldkontras ). Boomhoogtes wat met die hand bepaal is vanaf IRS-I C beelde is 95% akkuraat in vergelyking met die hoogtewaardes verkry vanaf die lugfoto's en die veldmetings. Die toepassing van beeldverbeteringstegnieke het duidelike invloede op die akkuraatheid van die IRS-IC stereomodel met afwykings van ongeveer -57m vanaf die "werklike" waardes. Daar is ook waargeneem dat beeldooreenstemming slegs 'n probleem is waar terreinvorme se voorkoms verander het (weens afkappings of brande) gedurende die verkrygingsperiode waarin die stereo paar van die satellietbeelde verkry is. LH Systems se Aanpassende Outomatiese Terrein Onttrekkings (Adaptive Automatic Terrain Extraction - AATE) instrument het goed gevaar tydens die gebruik van digitale lugfotografie met Inhoë skanderingstempo. In kontras hiermee het die outomatiese skepping van kroondakoppervlakmodelle van verskeie plantasievakke geen nuttige resultate gelewer wanneer dit op IRS-I C beelde toegepas is nie. Die growwe ruimtelike resolusie van die satellietbeelde tesame met die wye paalspasïering (20m) en passingsfoute is waarskynlik vir hierdie swak resultate verantwoordelik. Twee-fase proefueming en die Hugershoff metode was gebruik vir die bepaling van outomaties afgeleide hoogtewaardes vir evaluering van moonlike toepassing in bosvoorraadopnames. Geen bruikbare resultate kon verkry word vir die vasstelling van die regressieskatter vir die eersgenoemde metode of vir die berekening van die houtvolume volgens die Hugershoff metode nie. Dit is meestal as gevolg van beeld-- ooreenkomsfoute en flaters, (wat tot boomhoogtes van -885m gelei het) wat nie voldoende in ag geneem word in die terreinekstraksie sagteware nie. Die resultate vir die handgemete ('manual') boomhoogtebepaling wat uitgevoer is op die satellietbeelde (op die sagtekopie werkstasie DPW 770), toon dat akkuraathede soortgelyk aan daardie vir hoogte bepaal op klein-skaal lugfotos onder optimale toestande verkry kan word, maar goedkoper. Die hoogtewaardes wat verkry is kan gebruik word vir die berekening van houtvolume volgens die wet van Eichhorn.

Abstract:

A digital timbermarket helps forest owners reach out to severaltimber purchasers and be able to compare the forest companies’ price lists. The purpose of this study was to examine how the forest owners would respond to a digital timbermarket.The study analyzes if Swedish forest owners are interested in the use of a digital timbermarket. By using a web survey, the forest owner’s responses about a digital timbermarket have been collected and analyzed. The results of the study showed that most of the forest owners were positiveabout using a digital timbermarket. The forest owners who were positive usually had smaller properties, no education or work experience in forestry.Those who were most unwillingto use a digital timbermarket were mostly over 70 years old, had made more than 30timber sales and own forest properties over 300 hectares. En digital virkesmarknad är en webbplats där skogsägaren kan nå ut till flera olika virkesköpare vid försäljning av virke, köpare somskogsägarna i vanliga fall inte nått ut till. Här finns även offentliga prislistor från flera köpare samlade och detta kan på så sätt leda till en trasparantare virkesmarknad. Frågan är om skogsägare i Sverige är intresserade av att sälja virke genom en digital virkesmarknad, där olika bud kan jämföras. Om skogsägarna är det, vilka skogsägare är i så fall öppna för en digitaliserad marknad och vilka vill fortsätta sälja på traditionellt sätt. För att ta reda på hur intresset ser ut, har en webbenkät publicerats på Internet där skogsägare från hela Sverige kunnat fylla i enkäten. Totalt svarade 173 skogsägare. Deras svar har sedan sammanställts och analyserats för att se vad som skiljer skogsägare som är intresserade av att sälja virke genom en digital virkesmarknad från de som hellre säljer virke på traditionellt sätt. Studien visade att majoriteten (72 %) av skogsägarna var intresserade av att sälja virke genom en digital virkesmarknad. De skogsägare som skulle kunna tänka sig använda en digital virkesmarknad vid försäljning av sitt virke har oftast mindre fastigheter, ingen skoglig utbildning, använder Internet dagligen, ägt skogsfastigheten mindre än 10år och därmed gjort färre virkesaffärer. De som inte skulle kunna tänka sig använda en digital virkesmarknad vid försäljning av sitt virke är oftast över 70år, fastigheten är på över 300ha och gjort fler än 30 virkesaffärer.

Abstract:

AbstractDigital platform research has focused mostly on global platforms, where the users of the platform are consumers. Business-to-business (B2B) digital platforms have received less attention. This study observes and provides an early report on a digital platform for forestry, bringing together forest companies, contractors, and forest machine manufacturers. The platform started in Finland, but it has begun to extent its scope to international markets as well. We present some early insights about the birth of the platform and the factors that have contributed to its success in the beginning. We also describe some aspects present in B2B platform governance and related forces. Finally, we provide a preliminary outlook of possible future directions of the platform and its ecosystem.

Abstract:

AbstractForests play a significant role in any circular economy strategy aimed at achieving sustainable development, human well-being, and national welfare. Forest fires are responsible for substantial losses in forest ecosystems and the valuable ecosystem services they provide. The Internet of Things (IoT) constitutes a collaborative ecosystem comprising smart devices, networking infrastructure, and advanced processing technologies that work together to create smart environments for end-users. This revolutionary technology ensures continuous access to information and facilitates the integration of people and data, contributing to a greener future. It offers effective methods and substantial technical support for forest and environmental sciences and sustainable forest planning and management. Despite the transformative impact of technology in various sectors, the forestry industry has been slow to embrace digital technologies. IoT can be effectively designed and implemented across all phases of forest fire management, transitioning it from a manual system to a digital one with widespread remote participation and governance. This transformation results in the development of more resilient forest landscapes in the face of climate change and external disasters. Achieving a consensus on measures, including hardware, software, and skill requirements, is crucial for ensuring effective information provision. Additional research methods and approaches are needed to address emerging economic, environmental, and social challenges, and there must be a general agreement on what aspects to measure and how to measure them.

Abstract:

The Lugoj Forest Administration is a subunit of the Timi? Forestry Directorate and is located in the western part of Romania in the hilly area of Timi? County. It has as its object of activity the application of the Romsilva strategy for the forests received under administration, the conservation and sustainable development of the publicly owned forest fund of the state, the management of the hunting and fishing funds assigned according to the law, the harvesting and valorization of specific forest products according to the legal provisions in conditions of efficiency economic, also exercising public service duties with specific forestry.[1] The management of forests represents the set of concerns and measures aimed at ensuring the bringing and keeping of forests in an appropriate state from the point of view of the ecological, economic and social functions that they perform. The inventory and record activity of the forest fund is based on topographical measurement works, pedological maps and parcel descriptions showing all the factors on which the production and optimal utilization of forest products depends. The aim of the paper was to update the cartographic base of the forestry fund of the Lugoj Forest Ring Road, of which only one production unit is presented, because the documentation is very extensive. [2] [3] A GPS was used for the topographic surveys of the boundaries of the forest bodies using the static method and the Stop & Go kinematic method, and the Autodesk AutoCAD - Raster Design package was used to process and draw up the cartographic documentation in order to create the thematic digital maps.

Abstract:

The study was carried out in pine stands of the North taiga region of the Arkhangelsk region. The purpose of the study was to determine the xylem temperature of Scots pine trees and calculate the optimal sample size. The air temperature was measured using a metometer MES-200, the xylem temperature of the trees was determined by a portable digital multimeter MY-64 at 5 points of the trunk at a height from 0 m to 2 m. It is shown that the side of the light does not affect the temperature of the xylem. It was found that the xylem temperature is less than the air temperature. It was determined that the optimal sample size for measuring xylem temperature is from 8 to 11 trees.

Full text

Abstract:

Imagery collected via Unmanned Aerial System (UAS) platforms has become popular in recent years due to improvements in a Digital Single-Lens Reflex (DSLR) camera (centimeter and sub-centimeter), lower operation costs as compared to human piloted aircraft, and the ability to collect data over areas with limited ground access. Many different application (e.g., forestry, agriculture, geology, archaeology) are already using and utilizing the advantages of UAS data. Although, there are numerous UAS image processing workflows, for each application the approach can be different. In this study, we developed a processing workflow of UAS imagery collected in a dense forest (e.g., coniferous/deciduous forest and contiguous wetlands) area allowing users to process large datasets with acceptable mosaicking and georeferencing errors. Imagery was acquired with near-infrared (NIR) and red, green, blue (RGB) cameras with no ground control points. Image quality of two different UAS collection platforms were observed. Agisoft Metashape, a photogrammetric suite, which uses SfM (Structure from Motion) techniques, was used to process the imagery. The results showed that an UAS having a consumer grade Global Navigation Satellite System (GNSS) onboard had better image alignment than an UAS with lower quality GNSS.

Abstract:

Tree cover maps derived from satellite and aerial imagery directly support civil and military operations. However, distinguishing tree cover from other vegetative land covers is an analytical challenge. While the commonly used Normalized Difference Vegetation Index (NDVI) can identify vegetative cover, it does not consistently distinguish between tree and low-stature vegetation. The Forest Cover Index (FCI) algorithm was developed to take the multiplicative product of the red and near infrared bands and apply a threshold to separate tree cover from non-tree cover in multispectral imagery (MSI). Previous testing focused on one study site using 2-m resolution commercial MSI from WorldView-2 and 30-m resolution imagery from Landsat-7. New testing in this work used 3-m imagery from PlanetScope and 10-m imagery from Sentinel-2 in imagery in sites across 12 biomes in South and Central America and North Korea. Overall accuracy ranged between 23% and 97% for Sentinel-2 imagery and between 51% and 98% for PlanetScope imagery. Future research will focus on automating the identification of the threshold that separates tree from other land covers, exploring use of the output for machine learning applications, and incorporating ancillary data such as digital surface models and existing tree cover maps.

Abstract:

In this paper, we introduce the concept of “Strategic Digital Information Operations” (SDIOs), discuss the tactics and practices of the SDIOs, explain the main political goals of state and non-state actors in engaging with SDIOs at home and abroad, and suggest avenues for new research. We argue that the concept of the SDIOs presents a useful framework to discuss all forms of digital manipulation at both domestic and international levels organized by either state or non-state actors. While the literature has examined the military-political impacts of the SDIOs, we still don’t know much about societal issues that the SDIOs influence such as emotive political mobilization, intergroup relations, social cohesion, trust, and emotional resonance among target audiences.

Abstract:

As every aspect of life – from job seeking to health care – moves online, digital connectivity is a daily necessity, not a luxury. Against the backdrop of the UK’s worst cost of living crisis in 40 years, discussions about fuel and food poverty are now joined by a new concern with what has become known as digital poverty – challenges affording the cost of online connectivity and devices. Using data from a survey of low-income households, this Policy Briefing explores the extent of digital poverty in the UK and shows how it can exacerbate other forms of poverty among the most disadvantaged households. It also shows how current fixes, including social tariffs aimed at the poorest in society, are not effectively addressing this critical issue.

Abstract:

The GEM program has facilitated the availability of new and converted surficial geology maps and associated digital datasets for large sectors of northern Canada, leading to about 70% of the north being mapped and digitally available. Development of the Surficial Data Model (SDM) and Canadian Geoscience Map (CGM) series have streamlined the publication process and created a common standard digital map format and geodatabase. Based on traditional and more recent remote predictive mapping methodologies, there are now three types of surficial geology CGM maps produced: Surficial Geology, Reconnaissance Surficial Geology, and Predictive Surficial Geology. The considerable number of new surficial geology maps published during GEM-1 and GEM-2, as well as upcoming map publications, has resulted in an increase of 12% map coverage north of 60?, constituting a significant and lasting legacy of the GEM Program.
