ABSTRACT

Between March and June 2020, activity in the major cities of Latin America declined due to containment efforts implemented by local governments to avoid the rapid spread of COVID-19. Our study compared 2020 with the previous year and demonstrated a considerable drop in tropospheric NO2 levels obtained by the SENTINEL 5P satellite in major Latin American cities. Lima (47.5%), Santiago (36.1%), São Paulo (27%), Rio de Janeiro (23%), Quito (18.6%), Bogota (17.5%), Buenos Aires (16.6%), Guayaquil (15.3%), Medellin (14.2%), Mexico (7.6%), Belo Horizonte (7.8%), La Paz (9.5%), and Brasilia (5.9%) registered statistically significant decreases in NO2 concentrations during the study period. In addition, we analyzed mobility data from Google and Apple reports as well as meteorological information from atmospheric reanalysis data along with satellite fields between 2011 and 2020 and performed a refined multivariate analysis (non-negative matrix approximation) to show that this decrease was associated with a reduction in population mobility rather than meteorological factors. Our findings corroborate the argument that confinement scenarios may indicate how air pollutant concentrations can be effectively reduced and managed.

ABSTRACT

What are patterns of gender and authorship in urban land science? Our bibliometric analysis shows that the proportion of women shrinks among highly productive, impactful, and senior authors, akin to a pyramid shape. First, women are only one in ten researchers with an h-index above the 95th percentile. Second, women are first authors on 20% of all influential papers cited more than one hundred times. Third, women publish less frequently (1.6 papers/year) than men (2.2). Fourth, women have shorter career lengths (9.4 years) than men (11.8). Since the 2000s, citation rates for women and men have converged. For the generation starting careers since 2016, the proportion of women with an h-index above the 90th percentile increased to 25%. During the Covid-19 pandemic, there was a 51% increase in productivity for women. Despite these changes, gender disparities in urban land science are most pronounced among the most productive and impactful authors.

ABSTRACT

Google Earth Engine (GEE) is a geospatial processing platform based on geo-information applications in the ‘cloud'. This platform provides free access to huge volumes of satellite data for computing, and offers support tools to monitor and analyse environmental features on a large scale. Such facilities have been widely used in numerous studies about land management and planning. Considering the current lack of relevant overviews, it may be useful to evaluate the utilization paths of GEE and its impact on the scientific community. For this purpose, a systematic review has been conducted using the PRISMA methodology based on 343 articles published from 2020 to 2022 in high-impact scientific journals, selected from the Scopus and Google Scholar databases. After an overview of the publishing context, an analysis of the frequency of satellite features, processing methods, applications are carried out, and a special attention is given to the COVID-19 studies. Finally, the geographical distribution of the reviewed articles is evaluated, and the citation impact metrics is analysed. On a bibliometric approach, 90 journals published articles on GEE in the reference period (January 2020 to April 2022), and this large number of journals reveals the multidisciplinary application of GEE platform as well as the interest of publishers towards this topic of relevance for the international scientific community. The results of the meta-analysis following the systematic review showed that: (i) the Landsat 8 was the most widely-used satellite (25%);(i) the non-parametric classification methods, mainly Random Forest, were the most recurrent algorithms (31%);and (iii) the water resources assessment and prediction were the most common methodological applications (22%). A low number of articles about COVID-19, in spite of the planetary importance of the pandemic effects. The reviewed articles were geographically distributed among 86 countries, China, United States, and India accounting for the large number. ‘Remote Sensing' and ‘Remote Sensing of Environment' were the leading journals in the citation impact metrics, while the Random Forest method and the agriculture-related applications being the mostly cited. It is expected that these results might change over the mid to long term, due to fast progress in environmental and spatial information technologies, although currently our findings may be worthwhile and useful for assessing the current global deployment of GEE platform.

ABSTRACT

The coronavirus pandemic has changed the importance of biosecurity in the supply of agricultural produce, with impacts on the transport of goods and people domestically and globally. During the period of the pandemic, the Australian Government has continued to invest in biosecurity to better target critical biosecurity risks. This commitment includes a $371 million biosecurity package to keep out exotic pests and diseases. This investment assists with building the necessary capability for early detection of animal and plant pest and disease risks, and minimising the negative impact on farm income, the environment and the local economy. This report focuses attention on the biosecurity challenges on-farm for five small and emerging industries, and presents several biosecurity sensing technologies that have the potential to improve detection and analyse risk. It showcases technologies to manage biosecurity at the farm level as well as at industry and regional levels to strengthen Australia's national biosecurity system.

ABSTRACT

Not many efforts have been made so far to understand the effects of both the 2015-2016 drought and the 2020 lockdown measures on the agricultural production of smallholder vis-a-vis commercial farmers in Kwazulu-Natal. Google Earth Engine, and random forest algorithm, are used to generate a dataset that help to investigate this question. A regression is performed on double differenced data to investigate the effects of interest. A k-mean cluster analysis, is also used to determine whether the distribution patterns of crop production changed with drought and disruption of agricultural production input. Results show that: (1) droughts affected the agricultural production of both areas similarly. Crop cover declined in both areas for one season after droughts were broken. Then recovery was driven by greener, more productive crops rather than the expansion of crop area. (2) The response of both areas to the COVID-19 lockdown was also similar. Both smallholder and commercial areas' Normalised Difference Vegetation Index - a proxy for crop vitality - improved in response to regulations favourable to the sector and improved rainfall. No significant adjustments in crop cover were observed. Production therefore changed primarily at the intensive margin (improved productivity of existing croplands) rather than the extensive (changing the extent of land under cultivation). (3) Cluster analysis allows for a more granular view, showing that the positive impact of lockdowns on agriculture were concentrated in areas with high rainfall and close proximity to metropolitan markets. Both smallholder and commercial farmers therefore are reliant on market access together with favourable environmental conditions for improved production.

ABSTRACT

The COVID-19 epidemic swept the world and continued to spread. Without effective medical treatments and vaccine during the early stage of the pandemic, local governments in various countries had to lock down cities and adopt non-pharmaceutical interventions (NPIs), such as the stay-at-home order, social distancing, and so on. NPIs against the COVID-19 epidemic have significantly changed socioeconomic activities in cities. However, characteristics and patterns of urban socio-economic activities under this influence are still unclear. Benefiting from the development of earth observation technologies, such large-scale changes in socioeconomic activities are enough to be captured by satellites through remotely sensed night-time lights (NTL). In this study, we selected 20 major cities in the United States including New York, Chicago and Los Angeles to analyze spatio-temporal variations of NTL caused by the lockdown of cities. The first round of COVID-19 epidemic occurred in the United States in mid-March 2020. Since March 2020, American cities have successively issued stay-at-home orders, but there are differences in the time and strictness of policy implementation. Large cities have a higher population density and a higher intensity of social activities, so they are more susceptible to infectious diseases. The diversity of lockdown dates and strictness of lockdowns in cities in the United States are conducive to investigating the spatio-temporal variations of NTL. We acquired monthly averaged NPP VIIRS products of February, March and April, 2020, which are from Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) onboard the Suomi National Polar-orbiting Platform (NPP). We further analyzed the spatial pattern, distance decay and disparities in land use types of changes in NTL. Results show that NTL generally dimmed by 5-8% in U.S. cities caused by the lockdown of cities. There are 6 cities where the luminous brightness has dropped by more than 10%: Chicago, Dallas, Denver, Detroit, Minneapolis, and St. Louis. Among them, Minneapolis has the largest decrease in luminous brightness, with a decrease of about 40% in March. The spatial change of NTL shows obvious "core-periphery" pattern that the reduction of NTL declines with the distance from the city center. This is mainly because the central area of the city is a concentrated commercial area. After the closure of the city, commercial activities have dropped significantly, resulting in an obvious reduction in NTL around city centers. The reduction of NTL varies among diverse urban land use types. In New York, NTL decreased the most on land for residence and aviation facilities by 12% and 11%, respectively. In Chicago, NTL generally decreased by 20% in all types of urban land, and NTL recovered after one month of the lockdown of cities in other urban land except sports facilities land. This study only analyzes the spatio-temporal changes of NTL. In the future, it can be combined with multi-source data to explain the driving force of NTL changes. Nighttime light remote sensing effectively reflects urban socio-economic dynamics with an important application in monitoring and assessing socio-economic impacts of emergencies. © 2022 National Remote Sensing Bulletin.

ABSTRACT

Learning management systems (LMS) have been evolving since the late 1990s as a category of specialized web-based software for educational content delivery and experience. LMS assumed pivotal importance in learning experiences due to the COVID-19 spread. In this software pool, MOODLE (Modular Object-Oriented Dynamic Learning Environment) is a seasoned open-source LMS framework that has been widely adopted by companies, schools, and the academic community. This work aims to set up the learning materials of the Remote Sensing course theoretical and practical modules of UNITO master’s degree in Geography and Territorial Sciences, on the LMS MOODLE and to adapt it considering the multi-disciplinary approach typical of the Geographic domain. Thanks to inherent LMS features and different plugins available on the platform, some analytical approaches originally optimized for face-to-face didactics, are re-developed to optimize the ingestion, classification, and delivery of learning materials through the LMS, to facilitate comprehension and access to such materials by students in the Remote sensing course. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Water clarity is a key parameter for assessing changes of aquatic environment. Coastal waters are complex and variable, remote sensing of water clarity for it is often limited by low spatial resolution. The Sentinel-2 Multi-Spectral Instrument (MSI) imagery with a resolution of up to 10 m are employed to solve the problem from 2017 to 2021. Distribution and characteristics of Secchi disk depth (SDD) in Jiaozhou Bay (JZB) are analyzed. Subtle changes in localized small areas are discovered, and main factors affecting the changes are explored. Among natural factors, precipitation and wind play dominant roles in variation in SDD. Human activities have a significant influence on transparency, among which fishery farming has the greatest impact. This is clearly evidenced by the significant improvement of SDD in JZB due to the sharp decrease in human activities caused by coronavirus disease 2019 (COVID-19).

ABSTRACT

In this present era of 21st Century due to the dangerous infected disease Covid-19 all over the world telemedicine has played a major role in many parts of the world for remote monitoring of the covid-19 patients. Still there are many gaps in online remote monitoring in telemedicine process and as a result effective monitoring of the patients is not possible in many areas in the world. The detection of patients from remote place is considered as need of the day. This study presents the new challenges in the area of telemedicine or e-healthcare system. In this study we carefully analysed the present telemedicine process and we found that effective application of IoT, blockchain technologies and data mining can enhance the telemedicine process. This paper presents the new challenges in IoT, blockchain technologies and data mining where the researchers can work to fill the gaps in telemedicine process.

ABSTRACT

Since the outbreak of the Ukrainian-Russian conflict on 24 February 2022, Ukraine’s economy, society, and cities have been devastated and struck on multiple fronts, with large numbers of refugees fleeing to neighboring countries. The lighting systems in Ukrainian cities have been severely restricted due to Russian missile bombing and curfew policies. The power shortages adversely affected the livelihoods of the Ukrainian residents dramatically. For a timely assessment of the power shortages’ extent and the affected population in Ukraine, this study tracked the dynamics of nighttime light emissions in Ukraine based on the newly developed daily Black Marble product (VNP46A2) from NASA. The results show that the average light radiance in Ukrainian urban areas has decreased by about 37% since the eruption of the war, with Kiev city being the most dramatic region, having a post-conflict decrease of about 51%. In addition, by introducing near-real-time population data, we have implemented a survey of the affected population in Ukraine suffering from war-induced power shortages. Estimates show that about 17.3 million Ukrainian residents were affected by power shortages. In more detail, the number of children under 10 years old was about 2.35 million (about 5.24% of the total population), while the number of elderly people over 60 years old was about 3.53 million (about 7.86% of the total population). Generally, the results of this study could contribute positively to the timely assessment of the impact of the conflict and the implementation of humanitarian relief.

ABSTRACT

Introduction: To evaluate and validate the use of a remote check application in real life to enable cochlear implant (CI) recipients or parent/caregivers to monitor at home their progress and to help their clinicians to determine and plan for clinical visits based on their needs. Method(s): A total of 110 implanted patients (age range: 6-77 years;12-month implant experience and familiarity with vocabulary for digits 0 to 9) were included in this study, in which each subject served as their own control. The test battery includes an implant-site photograph, impedance measurements, datalogs, questionnaires, speech perception, and aided threshold tests. Chi-square test was used for statistical analysis of the results obtained at home vs clinical setting. Result(s): In all but 2 cases (108/110, 98%) the test battery reached the same conclusion as the clinician in determining whether the recipient required any clinical action. Of recipients and parents/ caregivers, 90% (100/110) reported being "satisfied" or "very satisfied" if their clinic visits were based on results from the selfadministered remote test battery (P<.001). Reasons for satisfaction included the convenience of remote monitoring, the ability to request an appointment if needed, and the continued involvement of their clinician. Satisfaction ratings with the remote monitoring concept were moderately to strongly correlated with perceived improvement in convenience and time involved. Conclusion(s): Most respondents recognized that the remote check battery has the potential to save time, reduce costs, and increase the convenience of aftercare. The clinicians with remote check battery are adequately informed regarding patient management, appointment scheduling, and required clinical actions. This may also further support global case management during COVID-19 pandemic time of recommended social distancing.

ABSTRACT

Covid 19 has accelerated the use of digital technology for healthcare in Australia and Worldwide. This has created benefits and opportunities for changing the way we provide access, management and care for our patients, including telehealth, remote monitoring of glucose and provision of education. This has also created challenges with technology, patient engagement, resources and confusing nutritional messages in the media and social media. Common themes of over-restriction and overconsumption of food groups and carbohydrates are observed. What lessons have we learnt, and how can we best use technology for both the patient and clinician?.

ABSTRACT

Coronavirus disease (COVID-19) is a viral infection caused by the SARS-CoV-2 virus that first surfaced in December 2019. According to the World Health Organization, most persons infected with this virus suffer from mild to severe respiratory infections and recover without specific treatment or hospitalization. Some people, however, may acquire serious illnesses that need medical attention and isolation facilities. This paper investigates the use of multi-criteria decision analysis (MCDA) based on GIS technology to determine the optimal site selection for isolation hospitals for coronavirus patients in Nile Delta region in Egypt using the fuzzy analytical hierarchy process (F-AHP) and the weighted overlay tool analysis method (WOA). The research of isolation hospital site selection in Nile Delta governorates in Egypt is one of the areas that have received insufficient attention due to the current global coronavirus epidemic. Several criteria are applied to identify and select the isolation hospital location, including World Health Organization regulations, Egyptian Ministry of Health conditions, previous research studies, and field visits. Geodatabase is created using ArcGIS Pro software, and manual digitization is done. As a conclusion of the study, numerous additional optimal sites for isolated hospitals have been found and chosen. There are around 29 proposed ideal sites for isolated hospitals utilizing F-AHP and approximately 24 sites using WOA approach in Nile Delta region. These planned hospital locations might be permanent as a central hospital or temporary, to be relocated after the epidemic is over. The paper emphasizes the need to use the study criteria while selecting and defining the location of coronavirus isolation hospitals.

ABSTRACT

SESSION TITLE: Unique Uses of Pulmonary Function Tests SESSION TYPE: Rapid Fire Original Inv PRESENTED ON: 10/19/2022 11:15 am - 12:15 pm PURPOSE: Prevention of asthma exacerbations can be done through adequate self management at home. This study aimed to evaluate the feasibility and safety of a portable spirometer for unsupervised home spirometry measurements among patients with asthma. METHODS: A single center, prospective, single-arm, open study recruited 25 patients with moderate or severe asthma. After a 45 min video training session by a respiratory therapist, patients performed daily spirometry at home with the Spirobank Smart MIR mobile spirometry system that was bluetooth connected to the KevaTalk app. Each spirometry examination was recorded and evaluated according to the ATS/ERS acceptability and repeatability criteria. Patients had to perform at least three technically acceptable maneuvers with the KevaTalk app guiding them if they had a good or bad blow. The best value of the three maneuvers were used for subsequent analyses. Patients also entered their daily check ins and symptoms via the KevaTalk Asthma app, tracked their controller and rescue medication use, filled up ATAQ questionnaires as well as were reminded of their action plans. Data obtained from spirometry was reviewed by nurses and pulmonologist and the Keva365 remote monitoring platform prompted alerts based on patient checkins, use of medication and PEF values in the red or yellow zone. Any escalations based on nurse review were reported to the office. RESULTS: Mean age of the patients was 57 years. 1155 spirometry sessions were completed over the duration of 9 months of the study. Data for FEV1, FEV6, PEF FEV1/FVC, as well as the Best Predicted and LLN values was reviewed daily for patients. Flow volume loops during the sessions were reviewed to identify if the home spirometry was done correctly and retraining was provided if needed. The reported values were tracked over the duration the patient was enrolled in the Keva program. 60.9% of patients were found to have peak flows in their respective red zones at least once and 87% were found to have peak flows in their yellow zone at least once, during the course of the study. If 3 consecutive values were in the yellow or red zone along with worsening of symptoms, the physician's office was informed for further course of action. CONCLUSIONS: The COVID-19 pandemic led to paucity of in office spirometry and face-to-face visits for asthmatic patients. Increasing the availability of spirometry with handheld devices along with a remote monitoring platform is useful for improving asthma control and reducing the risk of asthma-related hospital admissions and deaths. CLINICAL IMPLICATIONS: Remote objective spirometry yields clinically meaningful information that helps with asthma patient management and prevent an exacerbation from becoming worse.

ABSTRACT

SESSION TITLE: Unique Uses of Pulmonary Function Tests SESSION TYPE: Rapid Fire Original Inv PRESENTED ON: 10/19/2022 11:15 am - 12:15 pm PURPOSE: Asthma is one of the most common chronic respiratory illnesses affecting quality of life of patients, mortality as well as a high impact on health care utilization. In the era of the COVID19 pandemic, telemedicine and remote patient monitoring (RPM) have been heavily utilized by healthcare systems and providers for patient care. In our pilot program at a large US healthcare center, we enrolled patients known to have asthma to evaluate how RPM could be of value to both the patients and providers. METHODS: Patients included in the study had a confirmed diagnosis of moderate/severe asthma, were at least 18 years of age, and had access to an Android/iOS mobile device with internet access. The patients were excluded from the study for any conditions that would prevent them from using an app such as visual, cognitive, or other impairments that may prevent the patient from being able to participate. Patients were provided with a connected mobile spirometer, the KevaTalk app on their phones and educational introductory sessions during 9 months of the study. Each patient had their action plan and list of medications entered into the Keva365 platform by the nurse or the patient themselves. We provided a baseline patient questionnaire to assess usefulness and evaluate the app features, an ATAQ questionnaire for asthma control and a Smoking cessation questionnaire. Patients were asked to check in daily into the app as green (no symptoms), yellow (some symptoms) or red (bad symptoms). Patients were asked to perform spirometry using a connected spirometer. Remote monitoring protocols were set up for patients which included specific requirements for alerts being escalated to the pulmonologists. We monitored check-ins, alerts, and escalations during the study time window. RESULTS: A total of 25 patients were included in this pilot. Mean age was 57 and majority (23) were female. A baseline questionnaire rating the app, indicated that ease of check-in and ease of modification to the patient's asthma plan were the two highest rated features. 2066 total check ins (1550 green, 506 yellow and 10 red checkins) and 1155 spirometry sessions were recorded during this period. 484 alerts were recorded and evaluated by the monitoring team, of which 37% required an escalation to the physician requiring an intervention which included transfer to a medical facility, change in respiratory medication or further education. CONCLUSIONS: Patient driven engagement along with a well executed RPM program leads to increased compliance and improved outcomes among patients with respiratory illnesses. CLINICAL IMPLICATIONS: Our findings demonstrate preliminary evidence of the clinical impact of respiratory focused remote monitoring combined with a process for triaging our pulmonary patients. Adoption by pulmonolgists and allergists of these digital remote programs can pave the way for reduced physican burden, improved outcomes and reduced costs.

ABSTRACT

SESSION TITLE: Lung Cancer Case Report Posters 2 SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: The outbreak of the SARS-CoV-2 virus identified a need for healthcare systems to transform in order to accommodate the large volume of patients. As a result, innovative new methods to monitor patients have emerged. One type of innovation are remote patient monitoring (RPM) devices, which allow for home vital sign (VS) measurements and telemonitoring. We present a case utilizing this technology to monitor a middle-aged male with metastatic colon cancer to the lung, who required regular debulking therapy as a means of palliation. CASE PRESENTATION: A 59 year-old male with a history of stage IV colon adenocarcinoma with metastasis to the lungs status post lung wedge resection and radiation therapy 7 years previously was found to have an enlarging left lower lobe (LLL) mass. Fiberoptic bronchoscopy revealed resurgence of his metastasis. While undergoing palliative chemotherapy, the patient became increasingly dyspneic. Serial PET CTs showed evolution of his left lung mass with left upper and lower lobe collapse due to endobronchial disease prompting bronchoscopy with argon plasma coagulation (APC) for tumor debulking within the left mainstem bronchus and dilation of the LLL airways. While the patient's symptoms improved, he became dyspneic over several months, and interval CT scans demonstrated invasion of the left mainstem bronchus with complete collapse of the left lung. Repeat dilation and APC were performed with improvement in symptoms. Due to rapid tumor growth, he was enrolled in the continuous RPM (CRPM) program for 24/7 nursing-led telemonitoring. He completed daily questionnaires on a vendor-provided digital tablet, and his VS, composed of heart rate (HR), respiratory rate (RR), SpO2, and temperature, were automatically uploaded to a network using an FDA-approved wearable device. Intermittent readings using peripheral devices to measure blood pressure and spirometry were gathered. His VS mirrored his tumor progression, indicated by elevation in his mean RR and HR while his SpO2 declined necessitating 2L of oxygen. Further evaluation showed tumor invasion into the left mainstem bronchus and began to invade his right mainstem. Successive APC and cryotherapy were performed every 2-3 months with a total of 8 debulking bronchoscopies. Once his disease progressed to obstruct his entire left mainstem, the patient unenrolled from the CRPM program and enrolled in hospice care. DISCUSSION: Several RPM devices have previously been used, but require self-reported VS rather than automated, continuous oximetry. Our CRPM program was piloted as a means to monitor COVID-19 patients following hospital discharge. However, our patient displayed benefit from his 180 day CRPM enrollment while receiving palliative tumor debulking procedures in order to fulfill his wish to maximize time at home. CONCLUSIONS: RPM devices offer a novel method of monitoring patients outside of healthcare facilities. Reference #1: Gordon WJ, Henderson D, DeSharone A, et al.

ABSTRACT

The unprecedented outbreak of Coronavirus Disease 2019 (COVID-19) has impacted the whole world in every aspect including health, social life, economic activity, education, and the environment. The pandemic has led to an improvement in air quality all around the world, including in Malaysia. Lockdowns have resulted in industry shutting down and road travel decreasing which can reduce the emission of Greenhouse Gases (GHG) and air pollution. This research assesses the impact of the COVID-19 lockdown on emissions using the Air Pollution Index (API), aerosols, and GHG which is Nitrogen Dioxide (NO2) in Malaysia. The data used is from Sentinel-5p and Sentinel-2A which monitor the air quality based on Ozone (O3) and NO2 concentration. Using an interpolated API Index Map comparing 2019, before the implementation of a Movement Control Order (MCO), and 2020, after the MCO period we examine the impact on pollution during and after the COVID-19 lockdown. Data used Sentinel-5p, Sentinel-2A, and Air Pollution Index of Malaysia (APIMS) to monitor the air quality that contains NO2 concentration. The result has shown the recovery in air quality during the MCO implementation which indirectly shows anthropogenic activities towards the environmental condition. The study will help to enhance and support the policy and scope for air pollution management strategies as well as raise public awareness of the main causes that contribute to air pollution.

ABSTRACT

In this investigation, an innovative combination of pixel-based change detection technique and object-based change detection technique is explored with the satellite images of Holy Masjid al-Haram, Saudi Arabia. The gray-level co-occurrence matrix (GLCM) method is used to quantify the texture of the remote sensing data through the texture classification approach on the satellite data in this work. GLCM produces results of the texture quantification in normalized form. Thus, applying a texture classification scheme on the satellite data is impressive to observe. Later maximum likelihood image classification approach is used for classification purposes. The classified information is categorized into four different classes. The kappa coefficient’s value and the overall accuracy for the pre- COVID classified study area are 0.6532 and 76.38%, respectively. During COVID, the classified study area presents the kappa coefficient and the overall accuracy of 0.7631 and 82.18%, respectively. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

The rapid spread of COVID-19 has highlighted the need for rapid and digital monitoring means for managing information relating to the spread of the virus. The researchers have produced some innovative experiments in this sense, using geomatics technologies and technologies for the treatment of Big Data. In this research, we used an integrated platform (still under experimentation and validation) that allows the treatment of Big Data to obtain forecast models that can be viewed in a GIS. The advantages of the proposed methodology are the ability to use and correlate a lot of data together through a single platform and view the results on a WebGIS platform. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

COVID-19 pandemic forced many countries to adopt lockdown measures, temporarily closing factories, diminish maritime traffic and reducing the mobility of people in the cities. Analysis from the Tropospheric Monitoring Instrument (TROPOMI) and Ocean and Land Colour Instrument (OLCI) on board Europe's Sentinel-5P, 3A/B respectively, for the first wave of the COVID-19, have shown a substantial improvement in air and water quality. More specifically, since COVID-19 lockdown until the end April, Lisbon and Porto were at their lowest PM10 levels of about 20% and a drop of 33% in 2 years, while Madrid had a significant drop since lockdown with vales significantly below 2018 levels but still close to 2019 levels. In terms of NO2 levels, Lisbon had an historical minimum of the last 2 years, dropping more than 40% during most of April 2020. Finally, Madrid had 2-year lowest level of more than 30% since lockdown. Concerning the water quality in the Portuguese coastal waters, it was verified an increase in water transparency since confinement started until May, accordingly to the Total Suspended Matter (TSM) indicator. From February to March, March to April and April to May there was a reduction in TSM levels of 17%, 37% and 53% respectively. © 2021 by SCITEPRESS - Science and Technology Publications, Lda.
