Correlação de imagens digitais

Resumo: Esta dissertação tem por objetivo elaborar a automação do processo de medição de alvo s ou feições imageados com a câmara de TV-HR-600. Neste processo de medição são empregados dois métodos de correlação . O primeiro método consiste em aplicar uma função de correlação a janelas de um estereopar de imagens digitais , para obter a correlação de áreas ao nível do pix el. O segundo método trata a correlação encontrada empregando a t e o r ia dos mínimos quadrados a um modelo matemático que remove as distorções geométricas e as diferenças sistemática s radiometricas inerente s ao processo de aquisição da imagem refinando o processo e elevando a precisão

STRATEGY FOR EXTRACTION OF FOURSQUARE’S SOCIAL MEDIA GEOGRAPHIC INFORMATION THROUGH DATA MINING

This aim of this paper is the acquisition of geographic data from the Foursquare application, using data mining to perform exploratory and spatial analyses of the distribution of tourist attraction and their density distribution in Rio de Janeiro city. Thus, in accordance with the Extraction, Transformation, and Load methodology, three research algorithms were developed using a tree hierarchical structure to collect information for the categories of Museums, Monuments and Landmarks, Historic Sites, Scenic Lookouts, and Trails, in the foursquare database. Quantitative analysis was performed of check-ins per neighborhood of Rio de Janeiro city, and kernel density (hot spot) maps were generated The results presented in this paper show the need for the data filtering process — less than 50% of the mined data were used, and a large part of the density of the Museums, Historic Sites, and Monuments and Landmarks categories is in the center of the city; while the Scenic Lookouts and Trails categories predominate in the south zone. This kind of analysis was shown to be a tool to support the city's tourist management in relation to the spatial localization of these categories, the tourists’ evaluations of the places, and the frequency of the target public

CONFLITO DO USO E COBERTURA DA TERRA EM ÁREAS DE PRESERVAÇÃO PERMANENTE NA CIDADE DE NITERÓI, RJ / CONFLICT OF USE AND LAND COVERAGE IN AREAS OF PERMANENT PRESERVATION IN THE CITY OF NITERÓI, RJ

As Áreas de Preservação Permanente (APP), de acordo com o terceiro Código Florestal de 2012, são espaços territorialmente protegidos com funções de preservar os recursos hídricos, garantir a estabilidade geológica, manter a biodiversidade e promover o bem-estar das populações. Entretanto, devido ao crescimento acelerado dos núcleos urbanos brasileiros com pouco planejamento por parte dos poderes públicos, as cidades passaram a conviver com diversos problemas ambientais devido ao uso irregular de tais espaços. Nesse contexto, este trabalho tem por objetivo analisar os conflitos de uso e cobertura da terra provenientes da ocupação irregular em Áreas de Preservação Permanente (APP) no município de Niterói. Para alcançar tal objetivo foi gerado o Modelo Digital de Elevação Hidrologicamente Condicionado (MDEHC) e utilizada a base cartográfica do IBGE em 1:25.000 de modo a mapear as APP. A seguir foi elaborado um mapa de uso e cobertura da terra usando imagem RapidEye e o método Máxima Verossimilhança obtendo uma exatidão global pelo coeficiente Kappa de 0,806. As APP ocupam 13,98% do município de Niterói, com destaque para a APP de faixa marginal com uma área de 11,54 km² ou 8,63%. Desse total, aproximadamente 69% das APP estão devidamente conservadas, enquanto 31% estão indevidamente ocupadas

Análise espaço-temporal de roubos e furtos de bicicletas na cidade do Rio de Janeiro

In 2015, the government of the State of Rio de Janeiro instituted the system of prevention of bicycle theft and robberies and illegal bicycle trade and began to systematically publicize the occurrences of crimes against the bicycle. The prevention of bicycle thefts and robberies encourages the use of this mode by the population. In this way, this paper makes a spatial temporal analysis of the bicycle thefts and robberies in the neighborhoods of the city of Rio de Janeiro, between June 2015 and June 2017, in order to know the schedule, neighborhoods and places where this type of event occurs in the city. Among the results obtained, it observed that thefts occur less during the night and are more frequent in neighborhoods near the beach. Robberies occur more in the afternoon, are more concentrated in some neighborhoods and tend to follow the train line and the BRT route. Knowledge and understanding of the distribution of bicycle robbery and robbery events in the city of Rio de Janeiro are important for police planning and assistance to cyclists.Em 2015, o governo do Estado do Rio de Janeiro instituiu o sistema de prevenção ao roubo ou furto e ao comércio ilegal de bicicletas e iniciou a divulgação sistemática das ocorrências registradas dos crimes contra a bicicleta. A prevenção destes delitos tende a incentivar o uso desse modal pela população. Destarte este trabalho efetua uma análise espaço-temporal dos roubos e furtos de bicicletas nos bairros do município do Rio de Janeiro, no período entre junho de 2015 até junho de 2017, visando conhecer o horário e locais onde mais ocorrem este tipo de evento. Dentre os resultados obtidos observa-se que os furtos ocorrem com menos frequência na madrugada e que são mais frequentes nos bairros da orla e que os roubos ocorrem mais no horário vespertino e que são mais concentrados e tendem a acompanhar a linha do trem e o trajeto do BRT. O conhecimento e a compreensão da distribuição dos eventos de roubos e furtos de bicicletas na cidade do Rio de Janeiro são importantes para planejamento do policiamento e assistência aos ciclistas

INFORMAÇÃO GEOGRÁFICA VOLUNTÁRIA NO PROCESSO DE REAMBULAÇÃO

Este trabalho apresenta uma metodologia para a construção de uma base de dados voluntária em um estudo de caso para coletar dados de postos de combustível no município do Rio de Janeiro e do seu entorno de modo a inserir na base de dados do OpenStreetMap. A partir dessa experiência apresenta uma reflexão sobre a inserção do mapeamento colaborativo no processo de reambulação das Agências Nacionais de Mapeamento de modo a promover uma atualização dinâmica das bases cartográficas e maior participação social nos processos de construção do território

A Methodology for GIS Databases Integration

The effective development of a Multidatabase (MDB) environment for integration of independent Geographic Information System (GIS) databases, requires a methodology to guide the users and Database Administrators, as well as the provision of a foundation for the development of tools to help the integration. The existing methodologies do not consider characteristics of the cartographic representation in the schemas nor do they take into account the semantic richness of geographic data. They are also limited to a given application domain or to specific information communities. This work presents MMultiGIS, a methodology for the integration of heterogeneous and distributed GIS databases. It has been developed for the MultiGIS System, which aims at providing semantic interoperability among GIS databases. MMultiGIS disciplines the activities during schema integration taking into account the spatial context, the application areas and the semantic and syntax of database schemas. This methodolog..

Avaliação dos Critérios de Elegibilidade do Programa Territórios da Cidadania

The Territories of Citizenship Program (PTC) is one of the most important territorial development policies in force in Brazil, especially regarding its scope and importance. The program features different scope, with territorial approach, social and inter-ministerial management. Despite the fact that the PTC is based in an evolutionary process of public policies, such as the National Program to Strengthen Family Agriculture (Pronaf) and Sustainable Development Program of Rural Areas (Pronat), it still presents certain bottlenecks, as the definition criteria for the choice of the territories. In this sense, the paper presents a statistical methodology with the objective of assessing the eligibility criteria and the importance level of these criteria for a municipality to be served by the program, from proxy indicators to the criteria set by decree. As a result, criteria such as population density, existence of quilombos and indigenous population did not show the expected role. But the Human Development Index is presented as the main eligibility criteria, showing that the index remains relevant for the monitoring and evaluation cycle of Brazilian public policy. Family farming, one of the main pillars of PTC and its predecessor programs, was also important, maintaining the consistency of the scope and objectives of the program
