O presente trabalho de projecto, realizado no âmbito do Mestrado em Gestão do Território, Área de Especialização em Detecção Remota e Sistemas de Informação Geográfica, ministrado na Faculdade de Ciências Sociais e Humanas (FCSH) da Universidade Nova de Lisboa, regista o trabalho desenvolvido sobre a constituição de geocomunidades de informação geográfica em meio empresarial. Este trabalho foi realizado com o apoio partilhado FCSH e Nokia Portugal. O trabalho projecto está dividido em duas partes. Uma primeira parte que consiste numa abordagem teórica sobre a evolução dos SIG, sobre o estado da arte, sobre a nova geografia (neogeography); contem também uma abordagem sobre o crowdsourcing e as suas funcionalidades e potencialidades, caracterização dos seus utilizadores e o seu valor económico e social. Esta primeira parte tem o intuito de tentar chegar a uma conclusão sobre qual a melhor opção para uma empresa, no que toca à criação de base de dados geográficas olhando para as variadíssimas opções que existem no mercado desde base de dados governamentais, às privadas até às base de dados de cariz voluntário e sem custo para o utilizador ao aceder a essa informação. A segunda parte, de natureza prática, pretende cruzar dados e informação sobre duas Expert-Community que foram criadas com o intuito de testar a plataforma Map-Wiki da Nokia durante doze meses. Apesar de ser uma parte mais prática, conta também com uma breve retrospectiva da Nokia e das aplicações baseadas em Global Position Systems, uma explicação sobre o que é o Nokia Here e uma comparação entre as várias propostas existentes no mercado.

The forest has a crucial ecological role and the continuous forest loss can cause colossal effects on the environment. As Armenia is one of the low forest covered countries in the world, this problem is more critical. Continuous forest disturbances mainly caused by illegal logging started from the early 1990s had a huge damage on the forest ecosystem by decreasing the forest productivity and making more areas vulnerable to erosion. Another aspect of the Armenian forest is the lack of continuous monitoring and absence of accurate estimation of the level of cuts in some years. In order to have insight about the forest and the disturbances in the long period of time we used Landsat TM/ETM + images. Google Earth Engine JavaScript API was used, which is an online tool enabling the access and analysis of a great amount of satellite imagery. To overcome the data availability problem caused by the gap in the Landsat series in 1988- 1998, extensive cloud cover in the study area and the missing scan lines, we used pixel based compositing for the temporal window of leaf on vegetation (June-late September). Subsequently, pixel based linear regression analyses were performed. Vegetation indices derived from the 10 biannual composites for the years 1984-2014 were used for trend analysis. In order to derive the disturbances only in forests, forest cover layer was aggregated and the original composites were masked. It has been found, that around 23% of forests were disturbed during the study period.

Crisis-affected communities and global organizations for international aid are becoming increasingly digital as consequence geotechnology popularity. Humanitarian sector changed in profound ways by adopting new technical approach to obtain information from area with difficult geographical or political access. Since 2011, turkey is hosting a growing number of Syrian refugees along southeastern region. Turkish policy of hosting them in camps and the difficulty created by governors to international aid group expeditions to get information, made such international organizations to investigate and adopt other approach in order to obtain information needed. They intensified its remote sensing approach. However, the majority of studies used very high-resolution satellite imagery (VHRSI). The study area is extensive and the temporal resolution of VHRSI is low, besides it is infeasible only using these sensors as unique approach for the whole area. The focus of this research, aims to investigate the potentialities of mid-resolution imagery (here only Landsat) to obtain information from region in crisis (here, southeastern Turkey) through a new web-based platform called Google Earth Engine (GEE). Hereby it is also intended to verify GEE currently reliability once the Application Programming Interface (API) is still in beta version. The finds here shows that the basic functions are trustworthy. Results pointed out that Landsat can recognize change in the spectral resolution clearly only for the first settlement. The ongoing modifications vary for each case. Overall, Landsat demonstrated high limitations, but need more investigations and may be used, with restriction, as a support of VHRSI.

L'explosió d'aplicacions a Internet basades en oferir serveis de localització, com són portals web de mobilitat o aplicacions de seguiment de vehicles en línia han motivat aquest projecte. Google Maps ens permet afegir mapes fàcilment en un lloc web amb la seva API, però OpenLayers, una llibreria JavaScript lliure ens dóna l'opció de carregar cobertures de mapa i marcadors des de qualsevol font. OpenStreetMap proporciona dades geogràfiques de manera lliure, com per exemple mapes de carrers i carreteres. Un estudi acurat de l'estructura i agrupació de les dades en el format OSM i el desenvolupament d'un servidor basat en el model de tessel·les, són els principals elements de partida per crear la nostra pròpia font de dades cartogràfiques. En aquest projecte s'analitza i processa DXF Drawing eXchange Format passant al format OSM. Un fitxer OSM conté la informació geogràfica necessària per a la base de dades espaial a partir de la qual, entre d'altres aplicacions, es podran visualitzar els mapes propis en una aplicació de seguiment de vehicles o en un portal web.

Nowadays, service providers in the Cloud offer complex services ready to be used as it was a commodity like water or electricity to their customers with any other extra effort for them. However, providing these services implies a high management effort which requires a lot of human interaction. Furthermore, an efficient resource management mechanism considering only provider's resources is, though necessary, not enough, because the provider's profit is limited by the amount of resources it owns. Dynamically outsourcing resources to other providers in response to demand variation avoids this problem and makes the provider to get more profit. A key technology for achieving these goals is virtualization which facilitates provider's management and provides on-demand virtual environments, which are isolated and consolidated in order to achieve a better utilization of the provider's resources. Nevertheless, dealing with some virtualization capabilities implies an effort for the user in order to take benefit from them. In order to avoid this problem, we are contributing the research community with a virtualized environment manager which aims to provide virtual machines that fulfils with the user requirements. Another challenge is sharing resources among different federated Cloud providers while exploiting the features of virtualization in a new approach for facilitating providers' management. This project aims for reducing provider's costs and at the same time fulfilling the quality of service agreed with the customers while maximizing the provider's revenue. It considers resource management at several layers, namely locally to each node in the provider, among different nodes in the provider, and among different federated providers. This latter layer supports the novel capabilities of outsourcing when the local resources are not enough to fulfil the users demand, and offering resources to other providers when the local resources are underused.

En aquest projecte es visualitza la trajectòria d'un vehicle (aeri o terrestre) en una pàgina web. Per això es disposa d'una PDA (Personal Digital Assistant), en la qual es té informació actualitzada de la posició i de la velocitat d’aquest vehicle. Aquestes dades són obtingudes d'un sistema que combina la navegació inercial i el GPS (Global Position System), els quals estimen de manera precisa la trajectòria del vehicle. A fi d'oferir una visualització en temps real, versàtil, accessible i amigable a l'usuari de la trajectòria del vehicle, s'ha desenvolupat un sistema de visualització on-line que proporciona un millor rendiment en comparació amb la qual es venia fent en la PDA. Per a dur-lo a terme s'implementa una interfície d'usuari en la PDA que ens permet transmetre aquesta informació via WIFI a la pàgina web, d'igual forma al servidor web es crea una interfície que interpreta i gestiona aquestes dades per a posteriorment ser graficats a Google Maps.

This article offers an overview of methodological difficulties that arise in the study of religions on video sharing websites (VSW). We suggest how to put these difficulties in perspective and how to overcome them. A typology lists the various forms of religions represented on this type of website. We will also try to understand why some religious groups have created their own video sharing websites. Finally we will give possible interpretations of this phenomenon and suggest some ways to use this type of material in academic research and teaching about religions. Cet article propose une vue d'ensemble des difficultés méthodologiques rencontrées dans l'étude des religions sur les sites web de partage de vidéos. Il propose des pistes pour relativiser et surmonter ces difficultés. Une typologie présente les différentes formes sous lesquelles on trouve des religions dans ce type de sites web. Nous tentons aussi de comprendre pourquoi certains groupes religieux ont créé leurs propres sites de partages de vidéos. Enfin, nous donnerons des possibles interprétations du phénomène et suggérerons comment on pourrait utiliser de ce type de matériel dans la recherche et l'enseignement académiques sur les religions.

Grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational resources. Grid enables access to the resources but it does not guarantee any quality of service. Moreover, Grid does not provide performance isolation; job of one user can influence the performance of other user’s job. The other problem with Grid is that the users of Grid belong to scientific community and the jobs require specific and customized software environment. Providing the perfect environment to the user is very difficult in Grid for its dispersed and heterogeneous nature. Though, Cloud computing provide full customization and control, but there is no simple procedure available to submit user jobs as in Grid. The Grid computing can provide customized resources and performance to the user using virtualization. A virtual machine can join the Grid as an execution node. The virtual machine can also be submitted as a job with user jobs inside. Where the first method gives quality of service and performance isolation, the second method also provides customization and administration in addition. In this thesis, a solution is proposed to enable virtual machine reuse which will provide performance isolation with customization and administration. The same virtual machine can be used for several jobs. In the proposed solution customized virtual machines join the Grid pool on user request. Proposed solution describes two scenarios to achieve this goal. In first scenario, user submits their customized virtual machine as a job. The virtual machine joins the Grid pool when it is powered on. In the second scenario, user customized virtual machines are preconfigured in the execution system. These virtual machines join the Grid pool on user request. Condor and VMware server is used to deploy and test the scenarios. Condor supports virtual machine jobs. The scenario 1 is deployed using Condor VM universe. The second scenario uses VMware-VIX API for scripting powering on and powering off of the remote virtual machines. The experimental results shows that as scenario 2 does not need to transfer the virtual machine image, the virtual machine image becomes live on pool more faster. In scenario 1, the virtual machine runs as a condor job, so it easy to administrate the virtual machine. The only pitfall in scenario 1 is the network traffic.
