Geografická data se stala nedílnou součástí každodenního života. Nejběžnější vizualizací geografických dat je statická tematická mapa. Ta ovšem vizualizuje pouze jeden časový okamžik, případně několik z nich, agregovaných dohromady. Bez času navíc není možné vizualizovat geografické jevy, jako je vývoj různých geografických charakteristik (např. růst emisí uhlíku nebo šíření viru). Cílem této práce je vytvoření nástroje pro vytváření vizualizací geografických časových řad, které umožní data prezentovat a studovat. Řešení je vyvinuto jako nástroj aplikace Geovisto. Vyvinutý nástroj umožňuje uživatelům vytvářet vlastní vizualizace a animace geografických časových řad a zároveň je konfigurovatelný pro použití s obecnými daty. Uživatelé se znalostí programování mohou vytvářet nové Geovisto nástroje (např. tematické mapy) a pomocí nástroje pro práci s časem sami implementovat animace do nových tematických map.

Background: Working from home (WFH) has become a new tendency thanks to the improvement of technological communications that enable new flexible ways of working. Before 2020 and the Covid19 pandemic, some companies had already started implementing this approach. However, the pandemic drove a widespread implementation of remote work, leading to the appearance of new problems previously not considered by most companies and individuals. Among these problems is the effect of WFH on the employee’s career perspective as well as the lower visibility in the workplace which could have an impact in future promotions. Objectives: The main research phenomenon to be studied is the impact of WFH on career prospects for engineers and in particular the paradox between visibility at work and the career progress of the employees. Methodology: The contribution of this thesis is a fourfold. First, it analyses the effect of visibility when WFH on engineers’ career perspectives. Second, it proposes a framework that relates WFH, visibility and career. Thirdly, it contributes to the existing literature on WFH, visibility and career. Lastly, it uses the innovative method of questerview, involving twelve engineers working on R&D department of an aeronautical company, to finally develop a thematic analysis and generate a new framework to be discussed with the first, according to the grounded theory method. Results: The results showed that WFH has an impact on career progression with a decrease invisibility, affecting it through personal relationships. WFH also affects other factors (such as networking and soft-skills) and these have a connection with visibility that, all together, will have a high impact in the career promotion rate. Other findings include the necessity to work on visibility by prioritizing the meetings with the right people in order to become more allegeable for promotion. Visibility affects the trust between manager and employee, due to the fact that the latter becomes much more dependable on deliverables when comparing to working in the office. WFH doesn’t affect visibility for career promotion if credibility with managers has been achieved, this being connected with job quality. Conclusions: WFH and visibility have both a high impact on the engineer’s career progression. The first reduces direct contact with peers and superiors, which in turn decreases visibility. Visibility has been found to be an essential tool for promotion. Its effect on career promotion works as the enabler to promotion, making superiors notice your work and keeping the employee in their minds to consider when a promotion is proposed. Visibility has not solely an impact on career promotion, but it has a connection between networking and soft-skills, and these three factors are directly related to one another when considering the influence on career promotion. Recommendations for future research: The relationships between factors in the literature review framework need to be studied further, in line with the cross connections found in the new framework. Also, during the elaboration of the thematic maps, it was also found that WFH has an impact on daily work (affecting autonomy, networking, and productivity) and additional research would enrich the final framework. Lastly, it was found during the questerview analysis that other factors not considered in the present study are also relevant for career promotion such as age, education level and experience. Future research could focus on studying the impact these factors have on career promotion.

Middle school students work with many types of maps in school, however most maps they use are qualitative thematic maps that only show differences in kind as compared to quantitative thematic maps that show differences in amounts. This thesis investigates sixth-grade students' abilities to analyze three types of thematic maps: dot maps, choropleth maps, and graduated circle maps. Two hundred and two Oregon sixth-graders were tested on their abilities to interpret map symbology, make inferences from the data, categorize values into regions, and ask geographic questions concerning data distributions. The results indicate that students can understand these three quantitative thematic maps for these purposes. These results also raise the question, "Why aren't there more quantitative thematic maps presented to students in middle school curriculum?"

Access to the to the Internet and to a variety of interactive mapping tools has increased interest among middle school teachers to use interactive maps in conjunction with learning activities. There is very little research in the area of interactive mapping in educational situations, specifically with regards to layer maps that combine multiple thematic layers on a single map. This study evaluates the relationship between the number of layers present on a web-based map and middle-school students' accuracy and timeliness using the map to answer geographic questions. Additionally, this study examines the specific effect of a hill shade on student response time and accuracy when answering questions do not require any terrain information. Tests were conducted in five Portland, Oregon area middle school classrooms using Blackboard CE8 to present maps and collect responses. The results of this research indicate no significant relationship between the number of layers present on a web map and middle school students' accuracy or response times while using the map to answer questions. The presence of a hillshade layers does not significantly impact the students' response times or accuracy while answering questions while using the map either.

O uso de veículos aéreos não tripulados (VANTs) tem se tornado cada vez mais comum, principalmente em aplicações de uso civil. No cenário militar, o uso de VANTs tem focado o cumprimento de missões específicas que podem ser divididas em duas grandes categorias: sensoriamento remoto e transporte de material de emprego militar. Este trabalho se concentra na categoria do sensoriamento remoto. O trabalho foca a definição de um modelo e uma arquitetura de referência para o desenvolvimento de sensores inteligentes orientados a missões específicas. O principal objetivo destas missões é a geração de mapas temáticos. Neste trabalho são investigados processos e mecanismos que possibilitem a geração desta categoria de mapas. Neste sentido, o conceito de MOSA (Mission Oriented Sensor Array) é proposto e modelado. Como estudos de caso dos conceitos apresentados são propostos dois sistemas de mapeamento automático de fontes sonoras, um para o caso civil e outro para o caso militar. Essas fontes podem ter origem no ruído gerado por grandes animais (inclusive humanos), por motores de combustão interna de veículos ou por atividade de artilharia (incluindo caçadores). Os MOSAs modelados para esta aplicação são baseados na integração de dados provenientes de um sensor de imageamento termal e uma rede de sensores acústicos em solo. A integração das informações de posicionamento providas pelos sensores utilizados, em uma base cartográfica única, é um dos aspectos importantes tratados neste trabalho. As principais contribuições do trabalho são a proposta de sistemas MOSA, incluindo conceitos, modelos, arquitetura e a implementação de referência representada pelo sistema de mapeamento automático de fontes sonoras. / The use of unmanned aerial vehicles (UAV) has become increasingly common, particularly in civilian applications. In the military scenario, the use of UAVs has focused the accomplishment of specific tasks in two broad categories: remote sensing and transport of military material. This work focuses the remote sensing category. It address the definition of a model and reference architecture for the development of smart sensors oriented to specific tasks. The main objective of these missions is to generate thematic maps. This work investigates processes and mechanisms that enable the automatic generation of thematic maps. In this sense, the concept of MOSA (Mission Oriented Sensor Array) is proposed and modeled. As case studies, we propose two automatic mapping systems for on-the-ground generated sound sources, one for the civilian case and one for the military case. These sounds may come from the noise generated by large animals (including humans), from internal combustion engine vehicles or from artillery activity (including hunters). The MOSAs modeled for this application integrate data from a thermal imaging sensor and an on-the-ground network of acoustic sensors. The fusion of position information, provided by the two sensors, into a single cartographic basis is one of the key aspects addressed in this work. The main contributions are the proposed MOSA systems, including concepts, models and architecture and the reference implementation comprised by the system for automatic mapping of sound sources.

In the first area under study, the scaling of semivariance function method and spatial linear model with multiple independent replications was used. The structures of spatial variability of the potassium content in soil and soybean yield in five agricultural years were compared.

The same happens to build thematic maps according to the individual models compared to maps generated according to the spatial linear models with multiple independent replications. Comparing the maps originated by the scaled model and spatial linear model with multiple repetitions, high levels of accuracy were obtained, which implies similarity of thematic maps built with these two methods. In the second area under study the interest was to use the spatial linear model with multiple independent replications to study the spatial variability of soybean yield in both years as a function of covariates soil resistance to penetration (RSP) and bulk density (Dens) in the layers 0-0.10, 0.10-0.20 and 0.20-0.30 m deep. In both studies, the structure of spatial variability estimated by spatial linear model with multiple independent replications caused reduction of computational time in the adjustment of models and the generation of thematic maps. / O objetivo deste trabalho foi apresentar um estudo de variabilidade espacial em diferentes períodos de tempo de duas áreas experimentais utilizando modelos geoestatísticos escalonados e espaciais lineares gaussianos com repetições múltiplas independentes. Na primeira área em estudo utilizou-se o método de escalonamento da função semivariância e o modelo espacial linear com repetições múltiplas independentes. Compararam-se as estruturas de variabilidade espacial do teor de potássio no solo e da produtividade da soja em cinco anos agrícolas.

O mesmo ocorreu ao construir mapas temáticos segundo os modelos individuais comparados aos mapas gerados segundo os modelos espaciais lineares com repetições múltiplas independentes. Ao comparar os mapas originados pelo modelo escalonado e o modelo espacial linear com repetições múltiplas independentes, obteve-se índices de acurácia altos, o que implica em semelhança dos mapas temáticos construídos com estes dois métodos. Na segunda área em estudo o interesse foi utilizar o modelo espacial linear com repetições múltiplas independentes para estudar a variabilidade espacial da produtividade da soja em dois anos agrícolas como função das covariáveis resistência do solo à penetração (RSP) e densidade do solo (Dens), nas camadas de 0-0,10, 0,10-0,20 e 0,20-0,30 m de profundidade. Em ambos os estudos, a estrutura de variabilidade espacial estimada pelo modelo espacial linear com repetições múltiplas independentes ocasionou redução do tempo computacional no ajuste dos modelos e na geração de mapas temáticos.

Ao longo da planÃcie costeira de Icapuà foi definido um complexo conjunto de unidades geoambientais originado pela interdependÃncia evolutiva dos variados componentes morfolÃgicos e regida pelos fluxos de matÃria e energia orientados pelas flutuaÃÃes do nÃvel relativo do mar e mudanÃas climÃticas durante o QuaternÃrio. Para definir a integraÃÃo destes componentes elaborou-se uma proposta de zoneamento geoambiental dessa planÃcie localizada no extremo leste do Estado do CearÃ, nordeste do Brasil. O principal objetivo foi o de, atravÃs dos mapas temÃticos em escala de detalhe (geolÃgico, geomorfolÃgico, unidades de paisagens), definir as bases geoambientais para gestÃo planejada dos sistemas naturais. Esses resultados foram alcanÃados atravÃs da realizaÃÃo de um amplo levantamento bibliogrÃfico, atividades em campo para o mapeamento e a utilizaÃÃo de imagens de satÃlite de alta resoluÃÃo. Aliado à elaboraÃÃo dos mapas temÃticos e zoneamento ambiental foi possÃvel realizar estudos quanto à dinÃmica dos elementos socioeconÃmicos e ambientais, os quais possibilitaram a elaboraÃÃo de um diagnÃstico socioambiental com Ãnfase em Ãreas que foram consideradas de risco potencial. Com a definiÃÃo das vulnerabilidades e potencialidades dos componentes morfolÃgicos da planÃcie costeira, foram agrupadas Ãreas relativamente homogÃneas e sugeridas medidas de gestÃo para melhoria da qualidade ambiental e vida das comunidades litorÃneas. Esses resultados alcanÃados fazem parte do projeto âDe Olho na Ãguaâ desenvolvido pela FundaÃÃo Brasil CidadÃo em parceria com o Programa de PÃs-graduaÃÃo em Geografia da UFC com o apoio do Programa Petrobras Ambiental e da FundaÃÃo Cearense de Apoio ao desenvolvimento cientÃfico e TecnolÃgico (Funcap). / This dissertation analyzes the sustainability of the carcinoculture in the city of Fortim-CearÃ, taking into consideration environmental, social and technological aspects. The research aimed at identifying the main handlin g practices and the technology that has been adopted in the shrimp culture farms, and its contribution to a sustainable development of the activity. The study presents some forms of technology and handling practices that can be adopted by the farms, which are considered less environmentally impacting, and it also identifies the main impacts generated by the activity. Primary and secondary data were used. The primary data were obtained by means of an empirical research carried out in the city of Fortim, during the months of April and August, 2005. During these visits, questionnaires were applied, with semi-structu red and open questions. It was also possible to carry out interviews with representatives of governmental agencies and the business community. Secondary data were obtained by means of bibliographical research comprising theses, books and articles on the issue, as well as documents such as reports, Codes of Conduct, Federal and State govern ment directives, and assessments made by governmental agencies in charge of regulating and supervising the activity. In this study, tabular and descriptive analysis techniques and a modified version of the âForest Service of United States Agricultural Department (1986) methodology were applied. These methods made it possible to transform the qualitative variables into quantitative ones, through numerical values and weights so as to obtain a Significance Index of the technological, environmental and social variables. Upon the results obtained by these Indexes, it was possible to assess that the carcinoculture in the region is not developing on a sustainable basis, rejecting, therefore, the proposed hypothesis, according to which the handling practices and the technology that has been used in these farms are contributing for the development of the activity in a way that is in harmony with the environment. In spite of the existence of some initiatives that suggest that the sector is starting to take into consideration environmental matters, it is possible to affirm that the actions carried out by the sectorâs main entities have not been able to effectively promote the necessary changes in the behavior and conduct of the business, neither has it been able to call the attention to the importance of preserving the environment.
