Possibilities for Real-Time Monitoring of COVID-19 Pandemics

Possibilities for Real-Time Monitoring of COVID-19 Pandemics

Author(s): Ioan Voina,Luciana Oprea,Tudor Borşan / Language(s): English Issue: 28/2020

Pandemics have been a real challenge for all humanity since time immemorial, leading to the finding of scientific and medical solutions for long-term monitoring, the development of solutions for pharmaceuticals and equipment specialized in their treatment and healing, but also in the storage of information in the form of spatial data sets necessary for the analysis and study of the phenomenon of their transmission on the entire globe.The contemporary world is currently facing the pandemic caused by the SARS-CoV-2 virus, which is, from our point of view, probably one of the greatest disasters caused by human intelligence from World War II to the present day.This paper aims to reproduce and, why not, to propose at the international level the realization of a unique global real-time monitoring system of pandemics through geodetic sciences, using in this sense the technology based on GNSS systems for real-time monitoring of individuals invested with a certain type of virus, using technical equipment that includes systems that allow the use of GNSS technology who, through the interconnection between them and a digital database created in the GIS environment based on metadata, individuals invested and suspects can be monitored by existing specialized institutions at international, national and local levels, which can transmit useful information to each other in the fight against the pandemic created by COVID-19.

Analyzing the Sprawl of Built-up Areas Using Landsat Data and the Normalized Difference Built-up Index

Analyzing the Sprawl of Built-up Areas Using Landsat Data and the Normalized Difference Built-up Index

Author(s): Iosif Vorovencii / Language(s): English Issue: 28/2020

The sprawl of built-up areas is one of the most important anthropic changes which lead to the development of cities. This study analyses the sprawl of built-up areas around the city of Brașov, Romania, on the basis of two Landsat satellite images acquired in 1985 and 2019. The analysis was based on satellite images obtained through the difference between the NDBI and NDVI indices calculated for each satellite image. The results show that in the period 1985–2019 built-up areas around Brașov and its surroundings increased considerably (24.6%). Furthermore, it was noted that, although the reflectance of built-up areas varies very little from one season to the next, it can be influenced indirectly by the presence in the studied area of agricultural land and barren land whose reflectance is seasonal. This phenomenon led to confusion among built-up, agricultural land and barren land in mapping built-up areas.

Сторожевые «башни» Испиджаба в археологической картографии

Author(s): Baurzhan Abishevich Baitanayev,Mikhail Aleksandrovich Antonov,Azamat Adilovich Yergeshbayev,Anatoliy Khayrutdinovich Shayakhmetov / Language(s): Russian Issue: 3/2020

The mapping data based on earlier archaeological surveys with the use of modern GIS technologies were presented. A database with archaeological data on the monuments typologically related to Karaultobe and settlement monuments of the early-medieval period of the Isfijab historical and cultural district was compiled. The data under study are mostly the results of explorations and surveys of monuments such as Karaultobe. The analysis was performed with the help of the ArcGIS mapping software. The geographical coordinates of each Karaultobe and the altitude map were used separately. The geographical points is a set of data obtained using GPS during the field research (archaeological explorations in particular). The altitude map is high-resolution radar data available on the US Geological Survey website. A digital map with data on the visibility of the chains of monuments and their functioning in the settlements of the region was created. The maps were created not only for publishing data in various formats and for navigation, but also for works that include displaying study analyses as a database. The aim of the project is to create a series of maps: the main map, where all objects are displayed, as well as a number of detailed maps of certain regions and maps with the results of the landscape analysis. In this paper, only some maps – small with simplified annotations – were used.

Defi niowanie rynku właściwego w sektorze farmaceutycznym w sprawach antymonopolowych – rola Obwieszczenia KE w sprawie defi nicji rynku właściwego do celów wspólnotowego prawa konkurencji

Author(s): Katarzyna Racka,Weronika Herbet / Language(s): Polish Issue: 5/2020

The relevant market is one of the key concepts of competition law; its determination is a fundamental element of any antitrust procedure, both at the EU and national level, and a tool allowing entrepreneurs to assess their market position for the purpose of identifying potential risks related to implemented operational activities. One of the instruments used to ensure consistency in the definition of the relevant market in the practice of antitrust authorities is the European Commission Notice on the definition of relevant market for the purpose of Community competition law. The aim of this article is to assess its adequacy in the context of the application of antitrust law to entrepreneurs operating in the pharmaceutical sector. The paper includes a discussion of the legal nature and meaning of the above mentioned notice, a concise discussion of its content in terms of guidelines for determining the relevant market in product and geographic terms. On the basis of the characteristics of the pharmaceutical sector – its participant and product structure, as well as the main factors shaping competition on pharmaceutical markets – the authors analyze: whether the guidelines included in the Commission Notice remain adequate and up-to-date in this respect; on which criteria, for the purposes of their own internal analysis, should entrepreneurs operating in the pharmaceutical sector rely; and what are the possible desirable changes to the discussed soft law in order to adapt it to specific market realities.

Historisch-Geografische Informationssysteme (HGIS) in der Tourismusgeschichte: Transnationale Besucherströme des Ostseetourismus im 19. Jahrhundert

Historisch-Geografische Informationssysteme (HGIS) in der Tourismusgeschichte: Transnationale Besucherströme des Ostseetourismus im 19. Jahrhundert

Author(s): Jan-Hinnerk Antons / Language(s): German Issue: 3/2021

This essay serves a double purpose: First, to demonstrate the potentials of digital methods, particularly Historical Geographic Information Systems (HGIS), in researching tourism history. To this end, it uses the example of nineteenth-century Baltic Sea tourism in order to show what benefits, problems and challenges the use of digital methods entails. Given the volume of data, in this case thousands of entries from Nineteenth Century guest lists of six Baltic Sea resorts, digital tools prove to be crucial to visualize and analyze spatial patterns of early tourist’s mobility. Second, on the level of historiographical insights, the essay asks for explanations for the specific spatial patterns of tourism movements. It analyses the spatial origin of visitors of the Baltic Sea resorts Travemünde near Lübeck, Heiligendamm in Mecklenburg, Pernau (Pärnu), Arensburg (Kuressaare), Hanko (Hangö) and Mariehamn (Maarianhamina), all in the Russian Empire, in certain sample years throughout the nineteenth century. The hypothesis of a determination by traffic infrastructure proves to be of only limited relevance. Cultural and climatic factors play considerably more decisive roles in shaping the prevailing north-south and east-west directions of visitor streams.

3D Modeling Techniques for the Restoration and Conservation of Historical Buildings

Author(s): Cătălin Constantin Ceaușu,Silvia Alexandra Dreghici / Language(s): English Issue: 29/2020

In the restoration and conservation of historic buildings and monuments, for verification and repairs of any kind, accurate information on shape, size and architectural details are of utmost importance. The field of photogrammetry plays an important role in this process, through the possibilities of 3D modeling and representation of historical buildings and monuments. At present, there are a series of photogrammetric software with expertise in image processing algorithms, with digital photogrammetric techniques that establish the direction of development of the applied instruments. The process of photogrammetric modeling uses terrestrial and aerial images of the building attached to the solid model, obtaining a 3D realistic model. This is easily visualized, analyzed and modified by users, even in other fields, such as architecture or history. The advantage of the “multi-view 3D reconstruction technology” is the possibility to use images no matter the shooting distance, as long as each two images contain common points.

The influence of urban expansion on landslide evolution. A case study in Cluj-Napoca Municipality.

The influence of urban expansion on landslide evolution. A case study in Cluj-Napoca Municipality.

Author(s): Anna-Hajnalka Kerekes,Szilárd Poszet / Language(s): English Issue: 1/2022

In the case of Cluj-Napoca Municipality, the analysis of the landslides is a frequently discussed topic due to its complex geology and urban expansion tendency. In this study, we chose the Gruia Neighbourhood in order to map the landslide evolution and land-use/land-cover (LULC) changes which occured between 2003 and 2021. In order to use the post-classification Change Detection method, we applied the supervised classification technique on three satellite imageries (2003, 2009, 2021), which were validated by high Kappa coefficient values, as it follows: 0,892, 0,879 and 0,931. Comparing the three classified imageries, we could conclude that a transition between agricultural land to urban areas is visible, with a total decrease of the agricultural land by 40,69% and a total increase of the urban area by 24,47%. In the evaluation process of the influence of the LULC change on the landslide evolution, we could observe that the increase of the urban areas led to the increase of the surface of the landslides, moreover, the slided territories on urban areas have increased by 200%.

WATERSHED DELINEATION USING DIGITAL ELEVATION MODEL IN ARCGIS

Author(s): Paula Stoica,Ioan Corneliu Marțincu,Catrinel Raluca Giurma-Handley / Language(s): English Issue: 22/2022

The watersheds can be useful in defining the boundaries of the basin or to divide that basin into subbasins. This case study aims to create a boundary that represents the contributing area for a certain pour point. The watershed is delineated from the DEM(Digital Elevation Model) by calculating flow direction and flow accumulation and using them further into the analysis. To achieve this, ArcGIS will be used to perform the analysis leading to watershed delineation.

ELBİSTAN HAVZASI’NIN GENEL MORFOTEKTONİK DİNAMİKLERİNİN JEOMORFOMETRİK İNDİSLERLE ANALİZİ

ELBİSTAN HAVZASI’NIN GENEL MORFOTEKTONİK DİNAMİKLERİNİN JEOMORFOMETRİK İNDİSLERLE ANALİZİ

Author(s): Fatma Esen,Saadettin Tonbul / Language(s): Turkish Issue: 24/2022

In this study, the structural features affecting the geomorphological development of the Elbistan Basin were questioned with geomorphometric indices. In the inquiry, the effect of geological structure and tectonics on the acquisition of geomorphological characteristics of 25 sub-basins belonging to the Elbistan Basin was tried to be explained with quantitative data. For this purpose, drainage basin asymmetry (Af), transverse topographical symmetry factor (T), basin relief (Bh), relief ratio (Rh), basin shape index (Bs), hypsometric curve (Hc) and hypsometric integral (Hi) such as geomorphometric indices were applied. During the application, a 10x10 meter resolution Digital Elevation Model (DEM), geology data, active fault data and ArcGIS 10.7 package program from Geographic Information System (GIS) software were used. Quantitative data obtained from the indices (Af, T, Bh, Rh, Bs, Smf, Hc, Hi) applied to the basin gave consistent results with each other. In other words, based on the classifications made according to the degree of tectonic impact in the sub-basins, it is generally seen that the same sub-basins are in the same group. However, the sub-basins located in close locations were mostly in the same classes. Another geomorphometric index used to calculate the relative tectonic activity of fault segments in the shaping of the Elbistan Basin is Smf. When the results obtained from the Smf values applied to 15 basins were evaluated, it was determined that tectonics played a highly active role in the development process of the mountain fronts. Active tectonic and lithology played an important role in the different form of the sub-basins in the Elbistan Basin.

Analysis on the Dynamics and Vulnerability of the Areas Covered by Forests, Harghita County

Author(s): Gheorghe Badea,Ana Cornelia Badea / Language(s): English Issue: 32/2022

In this article the main topic of interest is to explore the analyzing possibilities of exploiting data available from multiple sources. We chose to use several methods of data investigation, as follows: in the GFW (GlobalForestWatch) geoportal; in the ArcGIS Online application created based on MapBuilder; in ArcGIS Pro. The results and conclusions were extracted based on charts and model elements, offered by the latest version of ArcGIS Pro. The purpose of this work consisted in integrating different sources of data regarding forested areas. Thus, it is revealed the importance of integrating the information that can be obtained in GIS with those from the geoportals of spatial data, all of which can bring benefits to the local administration for creating strategies. The obtained result draws attention to protected areas vulnerable to change by 2050, and also present in loss areas, constituting a starting point for the thorough monitoring of these areas.
