Analysis Of Social Networks

Technology-driven advances in the gathering, processing and delivery of big data are making it easier to monitor forests and make informed decisions over their use and management. This paper first describes how innovations in remote sensing and cloud computing are enabling generation of geospatial data more often, at lower cost and in more user-friendly formats. Second, it describes the evolution of systems and technologies to trace forest products, and agricultural commodities linked to deforestation, from source to final use. Third, it reviews the potential for emerging data mining technologies such as natural language processing, web scraping and computer vision to support forest policy analysis and augment geospatial data gathered through remote sensing. The paper gives examples of how these technologies are being used and may be used in the future to monitor and respond to deforestation, fire and natural disasters, improve governance by enabling faster and more comprehensive analysis of social networks, policies and regulations, and increase traceability and transparency within supply chains.

Technical Assessment

The role of remote sensing data in detecting, estimating, and monitoring socioeconomic status (SES) such as quality of life dimensions and sustainable development prospects has received increased attention. Geospatial data has emerged as powerful source of information for enabling both socio-technical assessment and socio-legal analysis in land administration domain. In the context of Korean (re-)unification, there is a notable paucity of evidence how to identify unknowns in North Korea. The main challenge is the lack of complete and adequate information when it comes to clarifying unknown land tenure relations and land governance arrangements. Deriving informative land tenure relations from geospatial data in line with socio-economic land attributes is currently the most innovative approach. In-close and in-depth investigations of validating the suitability of a set of geospatially informed proxies combining multiple values were taken into consideration, as were the forms of knowledge co-production. Thus, the primary aim is to provide empirical evidence of whether proposed proxies are scientifically valid, policy-relevant, and socially robust. We revealed differences in the distributions of agreements relating to land ownership and land transfer rights identification among scientists, bureaucrats, and stakeholders. Moreover, we were able to measure intrinsic, contextual, representational, and accessibility attributes of information quality regarding the associations between earth observation (EO) data and land tenure relations in North Korea from a number of different viewpoints. This paper offers valuable insights into new techniques for validating suitability of EO data proxies in the land administration domain off the reliance on conventional practices formed and customized to the specific artefacts and guidelines of the remote sensing community.

This article discusses a comparison of various numbers of islands in Indonesia; and it addresses a valid method of accounting or enumerating numbers of islands in Indonesia. Methodology used is an analysis to compare the different number of islands from various sources.  First, some numbers of  Indonesian islands were derived from: (i) Centre for Survey and Mapping- Indonesian Arm Forces (Pussurta ABRI) recorded as 17,508 islands; (ii) Agency for Geospatial Information (BIG) previously known as National Coordinating Agency for Surveys and Mapping (Bakosurtanal) as national mapping authority reported with 17,506 islands (after loosing islands of  Sipadan and Ligitan); (iii) Ministry of Internal Affair published 17,504 islands. Many parties have referred the number of 17,504 islands even though it has not yet been supported by back-up documents; (iv) Hidrographic Office of Indonesian Navy has released with numbers of 17,499; (v) Other sources indicated different numbers of islands, and indeed will imply to people confusion. In the other hand, the number of 13,466 named islands has a strong document (Gazetteer). Second, enumerating the total number of islands in Indonesia can be proposed by three ways: (i) island census through toponimic survey, (ii) using map, and (iii) applying remote sensing images. Third, the procedures of searching valid result in number of islands is by remote sensing approach - high resolution satellite images. The result of this work implies the needs of one geospatial data source (including total numbers of islands) in the form of ‘One Map Policy’ that will impact in the improvement of  Indonesian geographic data administration.

This paper presents some preliminary results from research on monitoring the urban growth of Shenzhen in China. Agriculture is still the pillar of national economies in many countries including China. Thus, agriculture contributes to population growth. Population growth follows either exponential or logistic growth models. These models can be examined using a time-series of geospatial data, mainly historical earth observation imagery from satellites such as LANDSAT. Such multitemporal data may provide insights into settlement analysis as well as on population dynamics and hence, quantify the loss of agricultural land. In this study, LANDSAT data of ten dates, at approximately five yearly intervals from 1977 to 2017 were used. The remote sensing techniques used for analysis of data for 40 years were image selection, then followed by geometric and radiometric corrections and mosaicking. Also, classification, remote sensing image fusion, and change detection methods were used. This research extracted the information on the amount, direction, and speed of urbanization, and hence, the number of hectares of agricultural land lost due to urban expansion. Several specific elements were used in the descriptive model of landscape changes and population dynamics of the city of Shenzhen in China. These elements are: i) quantify the urban changes, from a small town (37.000 people in the early 1970’s) to the megalopolis of around 20 million habitants today. ii) Examining the rate of urban extension on the loss of agricultural landscape and population growth. iii) The loss of food production was analysed against the economic growth in the region. iv) The aspects of loss of agricultural land, area of built-up urban land, and increase in population are studied quantitatively, by the temporal analysis of earth observation geospatial data. The experimental results from this study show that the proposed method is effective in determining loss of agricultural land in any city due to urbanization. It can be used by town planner and other stakeholders such as land surveyors and agriculture experts to mitigate the mushrooming of unplanned settlements in many town / villages and loss of land for agriculture which might cause problems in food security.

The article examines the methodological and theoretical issues of the formation of legal support for the digitalization of land relations in Ukraine. The author points out that the digitalization of land relations causes "profound" changes in their legal regulation and determines the clarification of the basic principles of land law of Ukraine. Thus, with the adoption of the Law "On National Infrastructure of Geospatial Data" laid the beginning of the formation in the land legislation of Ukraine the principle of availability of public data on land, which symbolizes the beginning of the era of digitalization of land relations. The essence of this principle is that all information provided by law and created in the process of maintaining the relevant state registers of land and related natural and other resources (geospatial data) as a multifaceted object of land and other legal relations are available to subjects of such legal relations in real time in the official form and to the extent that such access is provided by the computer equipment and software used by such subjects. As stated in the Concept of Development of the Digital Economy and Society of Ukraine for 2018–2020, digitization is the saturation of the physical world with electronic-digital devices, tools, systems and electronic communication between them, which actually allows integrated interaction of virtual and physical, ie creates cyberphysical space. In our opinion, this definition of digitization cannot be considered as correct. Firstly, saturation of the physical world with electronic-digital devices, means, systems and the establishment of electronic-communication exchange between them is neither the essence nor the purpose of digitalization, but is only a way to implement it. After all, the saturation of the physical world with electronic-digital devices can lead to any social result – both positive and negative. Secondly, the provision of integrated interaction of virtual and physical - the creation of cyberphysical space does not indicate how such cyberphysical space differs from ordinary physical space, in which social relations arise and are regulated by law. Therefore, the concept of digitalization needs to be clarified taking into account the specifics of the legal regulation of land relations. It is proved that the legal norms regulating the digitalization of public relations are an integral part of the administrative, civil, land and other branches of law. The conclusion is substantiated that the legal infrastructure of digitalization of land relations includes legal support for: 1) collection and formation of a system of information about the land using its remote sensing; 2) formation of promptly updated land databases; 3) the formation of a system of registers, portals and other service mechanisms that guarantee and provide access to such databases and the use of information about land in land legal relations. The author proves that legal support for digitalization of land relations is their legal regulation, the basic basis of which is information about the land (data-based legal regulation), which with the help of appropriate software includes the dynamics of qualitative and quantitative state of land in the mechanism of legal regulation of land relations, transforming this dynamic in such dynamics of land legal relations at which negative and positive changes in a condition of the earths automatically cause emergence, change, specification of the rights and duties of their subjects and form preconditions for application of the legal influence provided by the legislation on those subjects whose activity or inaction caused negative consequences in the condition of the lands. Finaly analysis of the modern system of land information required to ensure the digitization of land relations, gives grounds to identify such key components of its legal infrastructure as: 1) collection and formation of a system of such information through remote sensing of land (remote sensing); 2) formation of operatively updated land databases; 3) formation of a system of registers, portals and other service mechanisms, which guarantee and provide access to such databases and the use of information about land in land relations. Each of the selected elements of the system of information use in the process of digitization of land relations has a special legal mechanism.
