Spatial multicriteria decision analysis to potential beekeeping assessment. Case study: Montesinho Natural Park (Portugal)

The Multicriteria decision analysis is a tool to support decision-making in the identification of areas with the utmost beekeeping potential. This paper design a GIS multicriteria approach to assess the beekeeping potential. The development of a conceptual model structure requires the participation of stakeholders and experts in that process. The spatial Multicriteria Decision Analysis (MCDA) allowed defining the potential beekeeping map. The resulting maps can be used by the beekeepers associations to easily select the more suitable areas for the apiaries location or relocation and avoid prohibited areas by legal requirements.

Interoperabilidade, processamento e análise visual de dados geográficos

Esta dissertação apresenta uma arquitectura interoperável que permite lidar com a obtenção, manipulação, processamento e análise de informação geográfica. A aplicação 30, implementada como parte da arquitectura, para além de permitir a visualização e manipulação de dados dentro de um ambiente 30, oferece métodos que permitem descobrir, aceder e usar geo-processos, disponíveis através de serviços Web. A interacção com o utilizador é também feita através uma abordagem que quebra a típica complexidade que a maioria dos Sistemas de Informação Geográfica apresenta. O recurso à programação visual reduz a complexidade do sistema, e permite aos operadores tirar proveito da localização e de uma abstracção de um processo complexo, onde as unidades de processamento são representadas no terreno através de componentes 30 que podem ser directamente manipuladas e ligadas de modo a criar encandeamentos complexos de processos. Estes processos podem também ser criados visualmente e disponibilizados online. ABSTRACT; This thesis presents an interoperable architecture mainly designed for manipulation, processing and geographical information analysis. The three-dimensional interface, implemented as part of the architecture, besides allowing the visualization and manipulation of spatial data within a 30 environment, offers methods for discovering, accessing and using geo-processes, available through Web Services. Furthermore, the user interaction is done through an approach that breaks the typical complexity of most Geographic information Systems. This simplicity is in general archived through a visual programming approach that allows operators to take advantage of location, and use processes through abstract representations. Thus, processing units are represented on the terrain through 30 components, which can be directly manipulated and linked to create complex process chains. New processes can also be visually created and deployed online.

Apoio geoespacial a uma operação NEO

No âmbito das obrigações que o Estado Português tem em garantir a segurança dos seus cidadãos, é efetuada, em países ou regiões onde há comunidades nacionais, uma avaliação quanto ao risco de vida para os cidadãos nacionais que aí residam ou aí se encontrem, entendendo-se, à luz do direito internacional consuetudinário, que é legítima a eventual execução de intervenção militar de extração de nacionais não combatentes dessas zonas de risco. Este trabalho pretende contribuir para uma reflexão sobre o apoio geoespacial a uma operação de extração de cidadãos nacionais não combatentes, que se denomina NEO (non-combatant evacuation operation). Dada a importância do conhecimento holístico do ambiente operacional para os comandantes militares, os Sistemas de Informação Geográfica desempenham um papel fundamental em termos da análise, contextualização e visualização da informação geoespacial, sendo um precioso sistema de apoio à decisão. A tomada de decisão é efetuada com os contributos de várias áreas de conhecimento, sendo fundamental que o planeamento seja efetuado com base na mesma informação geoespacial, evitando a existência de uma multitude de dados geoespaciais nem sempre coerentes, atualizados e acessíveis a todos os que deles necessitam, pretendendo-se com este trabalho fornecer um contributo para resolver este problema. Aborda-se também a escassez dos dados geográficos nas zonas em que este tipo de operações se poderá desenrolar, a pertinência e a adequabilidade de utilização de dados espaciais abertos, os modelos de dados, bem como a forma como a informação pode ser disponibilizada.

Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo

The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And the elements of this space are always more than suffering direct or indirect influences as the flow in the port is expanded. Therefore, this region became subject to the accidental spillage of oil, because it presents a heavy traffic of ships of various sizes that can run aground or collide with oil causing accidental events. The study of geomorphological and sedimentological compositions of seafloor becomes important as more is known about the relationships between these parameters and associated fauna, and can identify their preferred habitats. The database background, acoustically collected along the proposed study area, is a wealth of information, which were duly examined, cataloged and made available. Such information can serve as an important tool, providing a geomorphological survey of the sedimentary area studied, and come to subsidize, in a flexible, future decision making. With the study area Port of Cabedelo, Paraíba - Brazil, this research aimed to evaluate the influence of the tidal surface and background in modeling the seabed, including the acquisition of information about the location of submerged rocky bodies and the depth of these bodies may turn out to be natural traps for the trapping of oil in case of leaks, and obtain the relationship between types of bed and the hydrodynamic conditions present in the region. In this context, for this study were collected bathymetric data (depth) and physical oceanographic (height of water column, water temperature, intensity and direction of currents, waves and turbidity), meteorological (rainfall, air temperature, humidity, winds and barometric pressure) of the access channel to the Port of Cabedelo / PB and its basin evolution (where the cruise ships dock), and includes tools of remote sensing (Landsat 7 ETM +, 2001), so that images and the results are integrated into Geographic Information Systems and used in the elaboration of measures aimed at environmental protection areas under the influence of this scale facilities, serving as a grant to prepare a contingency plan in case of oil spills in the region. The main findings highlight the techniques of using hydroacoustic data acquisition together bathymetric surveys of high and low frequency. From there, five were prepared in bathymetric pattern of Directorate of Hydrography and Navigation - DHN, with the depth in meters, on a scale of 1:2500 (Channel and Basin Evolution of Access to Port of Cabedelo), where there is a large extent possible beachrocks that hinder the movement of vessels in the port area, which can cause collisions, running aground and leaking oil. From the scatter diagram of the vectors of currents, it can be seen as the tidal stream and undergoes a channeling effect caused by the bidirectional effect of the tide (ebb and flood) in the basin of the Port of Cabedelo evolution in NW-direction SE and the highest speed of the currents occurs at low tide. The characterization weather for the period from 28/02 to 04/07/2010 values was within the expected average for the region of study. The multidisciplinary integration of products (digital maps and remote sensing images), proved to be efficient for the characterization of underwater geomorphological study area, reaching the aim to discriminate and enhance submerged structures, previously not visible in the images

O CADASTRO NACIONAL DE IMÓVEIS RURAIS (CNIR): IMPLICAÇÕES PARA OS PROJETOS DE REFORMA AGRÁRIA E PARA A TRIBUTAÇÃO FUNDIÁRIA NO BRASIL

Este artigo visa analisar as implicações decorrentes da implementação parcial do Cadastro Nacional de Imóveis Rurais (CNIR) para o Imposto Territorial Rural (ITR) e para os projetos de Reforma Agrária. Entendido como um elemento necessário para a compreensão da atual configuração territorial brasileira, o CNIR se apresenta como um sistema normativo no território, elaborado a partir de sistemas técnicos que se utilizam de tecnologias da informação (sistema de GPS, sensoriamento remoto orbital e sistemas de informação geográfica), operacionalizando um cadastro fundiário de maior precisão e atualizado regular e periodicamente. São apontadas as implicações diretas que o cadastro georreferenciado de imóveis rurais possui, como identificação de terras devolutas, reconhecimento de posses ilegais, inconsistências nos dados sobre a situação fundiária brasileira, além de sua relação com o sistema de tributação fundiária e as possibilidades de reforma agrária, analisando a sua utilização para a chamada Reforma Agrária de Mercado, promovida pelo Banco Mundial. O CNIR é, portanto, entendido como um elemento da densidade técnica e normativa do espaço geográfico e que ocasiona em novas formas de uso, organização e regulação do território brasileiro.

SIG Aplicado á Ánálise Espacial dos Assentamentos Comunitários no Parque Natural de Serra Malagueta

A preservação dos ecossistemas e das biodiversidades é atualmente uma preocupação mundial, devido às fortes ameaças de alterações climáticas que vem sendo sofridas a nível do globo. Cabo Verde, não foge à regra, devido a sua localização geográfica, aliadas às alterações climáticas e ações antrópicas, vem sofrendo fortemente a degradação dos seus recursos naturais, em todo o território nacional. Daí a atenção das autoridades Caboverdeanas, na definição e criação de espaços naturais “Áreas Protegidas”, através de regimes e medidas de proteção e preservação. O Parque de Serra Malagueta é uma área protegida com 774 hectares, gerida pela Direção Geral do Ambiente do Ministério do Ambiente Habitação e Ordenamento do Território, cujos objetivos baseiam-se na proteção e preservação das espécies animais e vegetais aí existentes, apostando fortemente numa luta constante que deve envolver as comunidades residentes, desempenhando deste modo, um papel fundamental nessa ação, e portanto torna-se importante o conhecimento dessas comunidades. Constitui o propósito deste trabalho, a aplicação do SIG para análise dos assentamentos comunitários, nas áreas afectas ao PNSM, tendo em vista diversos factores, que interferem na disposição e localização das habitações, produzindo mapas que servem como subsídio a uma gestão sustentável do espaço, tomada de decisões e fazer previsões. Os Sistemas de Informação Geográficas (SIG) sendo a mais moderna ferramenta para análise espacial, servirá como um ótimo suporte para essa análise, pois trata-se de fenómenos Geoespaciais. Definiu-se duas áreas amostrais; Serra Malagueta (Locotano, C. d’Asno, Posto), e Fundura (Fundura, Mato), recorreu-se ao GPS (Map76 S), e uma base cartográfica (Ortofoto mosaico Tif 2008) em papel, para a visualização e coleta dos dados. Foram coletados um total de 418 localizações georreferenciadas do edificado, entre privados habitacionais, públicos e sem definição. Os habitacionais fazem um total de 396 observações, aproximadamente 95% do total dos edifícios coletado

Construção das capacidades organizacionais de tecnologia da informação no contexto dos sistemas institucionais integrados de gestão da UFRN

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

Utilização de SIG na sistematização de ocorrências de trauma no SAMU-192 das cidades de Feira de Santana BA e Rio Claro SP

Considering current technological progresses, they prove to be useful tools to be increasingly exploited in order to meet the population's needs. Generally, in Brazil, the Mobile Emergency Services (SAMU) tend to be limited to the management of incidents, which undermines the efficiency of these bodies. In this context, this final dissertation aims to present the use of Geographic Information Systems (GIS) for the SAMU in the cities of Feira de Santana BA and Rio Claro SP, integrating occurrences data related to trauma by cold weapon injuries, injury by gun, and assaults, in the period 2012-2013, as well as census data. The study was developed in stages that included obtaining data related to trauma events linked to urban violence, and statistical Census data (2010), provided by the Brazilian Institute of Geography and Statistics (IBGE). Regarding the GIS, the free software Quantum GIS (QGIS) was adopted for processing and spatializing data, assuming the districts as units of study, in the urban area of the cities analyzed. The resulting research products were presented in thematic maps format, which conducted to a comparative analysis of the occurrences related to traumas. The achieved results were satisfactory, and a database in GIS was developed, integrating occurrences data by Cold Weapon Injuries (FAB), Injury by Gun (FAF) and Assaults with census data, allowing the proper use and update of the system. Making a comparative analysis between the two cities, it was possible to establish that Rio Claro presents more occurrences when it comes to FAF, FAB and Aggression recorded at SAMU per 100,000 inhabitants than Feira de Santana. Thus, although Rio Claro's population is about three times smaller than Feira de Santana's, it can be said that Rio Claro is a more violent city, considering the factors analyzed. It is possible to infer that the use of GIS applied to the SAMU in medium-sized cities is feasible, and it has the advantage...
