Gisplanet 2005 - II Conferência e Exposição sobre Informação Geográfica

Centro de Congressos do Estoril

Site oficial http://www.gisplanet.org

Seja espacial! Um "slogan" interessante! 

GIS PLANET 2005 takes place in a particular framework of human behavior change, strongly influenced by the shift to an era of growing mobility fed by Geographic Information.

Devices and technologies are not new but the emerging ability to fully integrate many human activities within a spatial framework of convergent functionalities and growing capacity is a driving force to new attitudes and patterns capable of revolutionize the current paradigm.

Mobility poses new challenges to Geographic Information, urging for geographic databases to deal with dynamics of spatial and time variability, setting the ground for an immense new generation of applications and becoming a key asset to global sustainable development, as a crucial component of the Earth’s Intelligence System.

BE SPATIAL is about everyone playing a role in the development of the global geographic information society.

BE SPATIAL!

Geographic Information Management in Local Government
Ian Gilfoyle and Peter Thorpe, cop. 2004
ISBN: 0748409351, 272 p.

Sumário: As early pioneers in the use of digital geographic data, many local governments in the UK were ahead of their counterparts in central government and the private sector in the application of GIS technology. To meet current challenges, local authorities must coordinate the latest technology with effective information management strategies, human and cultural issues, and organizational structures and processes. Geographic Information Management in Local Government examines the factors that are necessary to ensure that real benefits are delivered from the improved availability of geographic information.Written by two practitioners with extensive government experience, this four-part book examines supporting technology, the data that fuels it, and the human factors that help or hinder successful GIS implementation. Exploring the history of geographic information management in local government, this volume offers a pragmatic overview of the subject and what local authorities need to do in order to be successful. 
 

Thermal Remote Sensing in Land Surface Processes
Dale Quattrochi, Jeffrey C Luvall, cop. 2004
ISBN: 0415302242, 464 p.

Sumário: Although remote sensing is recognized as a powerful tool in the collection, analysis, and modeling of environmental data, less attention has been given to the use of thermal infrared (TIR) remote sensing. Thermal Remote Sensing in Land Surface Processes focuses on the utility of thermal infrared remote sensing data for understanding the fluxes and redistribution of materials as a key aspect of land surface processes and land-atmosphere interrelationships. This one-of-a-kind resource takes a practical approach to the use of thermal remote sensing data in landscape characterization and analysis. Providing a background on the theory and principles of TIR remote sensing, the book highlights the importance of information obtained from thermal data and compares it to the type of data obtained by other methods.

Um exemplo da importância dos mapas:

O Mar de Timor, situado entre Timor e a Austrália é o refúgio de uma enorme riqueza do povo timorense - o petróleo.







As reservas petrolíferas que aí encontradas contam-se entre as vinte maiores do mundo.

Vem sendo dito que a Indonésia "assegurou" o silêncio de determinados países oferecendo algo em troca , algo que pudesse interessar tanto militar como economicamente, a esses mesmos países.

Objectivamente, no dia 11 de Dezembro de 1989 , foi assinado entre a Indonésia e a Austrália , o chamado "Timor Gap Zone of Cooperation Treaty" (o Tratado de Cooperação para o Intervalo da Fronteira Marítima de Timor ainda não Determinada) Nele ficou referido que assim se removeria "uma fonte potencial de conflito bilateral ou regional".

O facto é que a Austrália concordara em reconhecer a anexação de Timor-Leste de maneira a poder haver negócio conjunto, austro-indonésio, nna exploração das reservas petrolíferas do Mar de Timor. O povo de Timor-Leste não entrou nas cogitações dos governantes dos dois países...

Portugal denunciaria o acordo austro-indonésio no Tribunal Internacional de Justiça, sem resultar qualquer efeito. Uma das razões alegadas pela Austrália foi a de nunca Portugal ter dado a conhecer qualquer interesse, antes de 1975, sobre a plataforma marítima.

Consequentemente a Austrália não aceita a alegação de que os timorenses tenham quaisquer direitos de soberania permanentes sobre os recursos de plataforma marítima do Intervalo.

Resumidamente poderíamos considerar que o ponto de vista do governo australiano demonstra uma interpretação do direito internacional segundo a qual os actos de agressão podem ser ignorados e que os violadores do direito internacional podem tornar-se os legítimos titulares do território de que se apoderaram.

New Technology For Navigating Without GPS

No more need for GPS!

Sweden (SPX) Mar 15, 2005

A new method for navigation at sea, independent of GPS, is being put forward in a dissertation from Linkoping University.

Today merchant marine, military, and recreational boat traffic all rely on the global satellite system GPS to determine their position at sea. But sometimes information from the system is incorrect. Poor visibility or lax attention can then spell disaster.

GPS can be jammed, either unintentionally or intentionally. Signals from the satellites can be interfered with by ice build-up on the vessel's antennas, by other communication equipment, or by physical obstacles. Submarines cannot usually use the system.

Doctoral student Rickard Karlsson at the Center for Control and Communication describes in his thesis how modern, simulation-based methods of treating signals can be used to monitor and, if necessary, to take over the GPS function on a vessel.

This technology, unique in the world, requires no external infrastructure and is not susceptible to interference. Instead, the vessel's own radar is used to measure the distance to surrounding shores, and this data is then compared with a digital sea chart.

In a submarine, information from sonar equipment is compared with a digital depth chart. In combination with data about the movement of the vessel, the correct position can be calculated.

The method is based on a mathematical algorithm, a so-called particle filter, which is installed as a program in the vessel's computer system.

There is no need for any further hardware to be installed beyond what is already on board. Preliminary trials show that the method works just as well as GPS in navigating an archipelago.

The dissertation Particle Filtering for Positioning and Tracking Applications deals with several other uses of the same principle: positioning industrial robots, tracking vehicles from another vehicle to avoid collisions, and tracking boats and ships from an airplane.

O estudo da biomimética pode ajudar a criar novos sistemas de informação geográfica.

The Internet is often likened to an organic entity and this analogy seems particularly appropriate in the light of some striking new visualizations of the complex mesh of Internet pathways.

The images are results of a new graph visualization tool, code-named Walrus, being developed by researcher, Young Hyun, at the Cooperative Association for Internet Data Analysis (CAIDA) [1].

Although Walrus is still in early days of development, I think these preliminary results are some of the most intriguing and evocative images of the Internet's structure that we have seen in last year or two.

A few years back I spent an enjoyable afternoon at the Monterey Bay Aquarium and I particularly remember a stunning exhibit of jellyfish, which were illuminated with UV light to show their incredibly delicate organic structures, gently pulsing in tanks of inky black water. Jellyfish are some of the strangest, alien, and yet most beautiful, living creatures [2].

Having looked at the Walrus images I began to wonder, perhaps the backbone networks of the Internet look like jellyfish?

Walrus is an interactive visualization tool that allows the analyst to view massive graphs from any position. The graph is projected inside a 3D sphere using a special kind of space based hyperbolic geometry. This is a non-Euclidean space, which has useful distorting properties of making elements at the center of the display much larger than those on the periphery.

Satellites Spy on Lives of Great White Sharks

Sharon Guynup
National Geographic Today

September 22, 2003

The great white shark is the largest predatory fish, much-feared and greatly maligned by humans. But despite their notoriety, little is known about their basic biology or habits, their numbers, where they go—where they mate and birth their young remains a mystery.

To answer these questions, scientists are using two types of satellite transmitters to track the whereabouts of great white sharks from each of the world's hotspots: South Africa, California, and Australia.

The most startling discovery was how much time these sharks were spending thousands of miles from land.

" One shark traveled 2,360 miles (3,798 kilometers) to Hawaii.

Another three were tracked to the subtropical eastern Pacific between Baja California and Hawaii, about 1,500 miles (2,414 kilometers) from land.

They spent up to six months there—and did lots of deep diving, down to nearly 2,000 feet (610 meters). Subsequent tagging corroborated these routes.

Wide-Ranging Sharks
"We assumed that these were coastal fish, hanging out in temperate waters, but found out that they spend about half their life in deep, subtropical waters," said Boustany.

Both Domeier's Mexican whites and Bonfil's South African whites also showed wide-ranging, deep-diving behavior. Bonfil followed one shark over three months that traveled 1,000 miles (1,609 kilometers) into unprotected waters in Mozambique.

Other researchers documented the same behavior across the globe. In 2000, scientists with the Commonwealth Scientific and Industrial Research Organization in Victoria, Australia, traced a young male shark's route from the Victorian Coast to Tasmania and back—1,830 miles (2,945 kilometers) in 129 days—until communication was lost.
