Topic: . Probing the Edge of the Universe from the Edge of the Earth: Searching for Cosmic Neutrinos at South Pole
遠征地球最邊緣，探索宇宙最邊緣 － 在南極搜尋宇宙微中子
■ Prof. Pisin Chen陳丕燊教授
Department of Physics & Graduate Institute of Astrophysics, National Taiwan University
This year (2012) marks the centenary of Victor Hess’s historical discovery of cosmic rays. Over the 100 years’ time, scientists further realized that the universe is filled with all sorts of elementary particles. By investigating these cosmic particles, we can gain knowledge about the universe that is complementary to what offered by the more traditional optical telescopes. Neutrinos, which is one type of elementary particles, is known to interact very weakly with other particles and therefore can travel across the entire universe freely. A neutrino telescope can therefore in principle help to probe into the deepest of the universe, which also corresponds to looking back to the earliest history of the universe. However since neutrino is weakly interacting, it requires a large target to intercept when it arrive to Earth. With its huge volume of pristine ice, Antarctica is an ideal place for building such neutrino telescopes. The Askaryan Radio Array (ARA) Neutrino Observatory is one of such attempts. When completed in 4-5 years, it will cover 100 km^2 in area, the largest neutrino telescope in the world. Taiwan has been playing a key role in the inception and the construction of the ARA project. This is the first major scientific project at the South Pole in the 100 years’ history of the Republic of China. In this lecture, we will introduce the science and technology of ARA and share with the audience the photos and videos taken at the South Pole in December 2011.

Topic: . Our Strategic Directions
■ Prof. Shin Wang 王鑫教授
Graduate Institute of Geography, Chinese Culture University
US National Research Council published “ Understanding the Changing Planet: Strategic
Directions for the Geographical Sciences＂in 2010.
1. How Are We Changing the Physical Environment of Earth’s Surface?
2. How Can We Best Preserve Biological Diversity and Protect Endangered Ecosystems?
3. How Are Climate and Other Environmental Changes Affecting the Vulnerabilities of Coupled Human–Environment Systems?
4. How and Where Will 10 Billion People Live on Earth?
5. How Will We Sustainably Feed Everyone in the Coming Decade and Beyond?
6. How Does Where People Live Affect Their Health?
7. How Is the Movement of People, Goods, and Ideas Transforming the World?
8. How Is Economic Globalization Affecting Inequality?
9. How Are Geopolitical Shifts Influencing Peace and Stability?,
10. How Might We Better Observe, Analyze, and Visualize a Changing World?
11. What Are the Societal Implications of Citizen Mapping and Mapping Citizens?
Among them, 10 and 11 are the major concerns of this Symposium.
In 2008, Vespucci Initiative for the Advancement of Geographic Information Science, and the Joint Research Centre of the European Commission published "Next-Generation Digital Earth" a position paper, that says since Vice President Al Gore delivered his forward-looking speech titled “The Digital Earth: Understanding our Planet in the 21st Century” at the California Science Center in Los Angeles on 31 January 1998, the following advancements can be observed, in terms of:
1. Organizing geographical information (Spatial Data Infrastructure, SDI)
2. Geography as a way to organize information
3. Geosensing the world
4. Innovation in supporting technology
The report also pointed out the weakness of current developments. To overcome the limitations, the report suggested that we need to set a new vision to concentrate our future effort, it contains the following 8 elements:
1. Not one Digital Earth, but multiple connected globes/infrastructures addressing the needs of different audiences: citizens, communities, policymakers, scientists, educationalists.
2. Problem oriented: e.g. environment, health, societal benefit areas, and transparent on the impacts of technologies on the environment
3. Allowing search through time and space to find similar/analogue situations with real time data from both sensors and humans (different from what existing GIS can do, and different from adding analytical functions to a virtual globe)
4. Asking questions about change, identification of anomalies in space in both human and environmental domains (flag things that are not consistent with their surroundings in real time)
5. Enabling access to data, information, services, and models as well as scenarios and forecasts: from simple queries to complex analyses across the environmental and social domains.
6. Supporting the visualization of abstract concepts and data types (e.g. low income, poor health, and semantics)
7. Based on open access, and participation across multiple technological platforms, and media (e.g. text, voice and multi-media)
8. Engaging, interactive, exploratory, and a laboratory for learning and for multidisciplinary education and science.
Base on this new vision, the report suggested10 research areas for our consideration.

Topic: . Issues for the Next Generation Digital Earth
■ Prof. Yea-Chung Ding 丁亞中教授
Dept. of Geography, Chinese Culture University
The term Digital Earth put forward by Al Gore in 1998 has come to represent a global technological initiative. Over the past few years, virtual globes have become popular for commercial, social and scientific applications and tools designed to support the realization of the Digital Earth vision, ranging from geo-browsers over online collaborative mapping tools to spatial data infrastructures have been developed. A decade later, some academics argued the vision of Digital Earth needs to be re-evaluated in the fields of information technology, data infrastructures, and earth observation.
Now it’s time to take a serious look towards the future of Digital Earth. With the intention of discussing ways to implement the vision of Next Generation Digital Earth, this speech intends to highlight some issues on revised framework, technology and key aspects for the Next Generation Digital Earth, to present an overview of the existing Digital Earth solutions that have been developed for the challenges faced by the world today, and to identify the next steps in research towards the Next Generation Digital Earth. Fields and directions of research in order to continue the realization of the Digital Earth concept have also been proposed, such as: Volunteered Geographic Information, Linked Geo-data, Information Visualization, Geospatial Semantic Web, Semantic Web Services, Future Internet Tools, and Geospatial Data Availability etc.

Topic: .Ecoinformatics: A New Paradigm for Biodiversity and Ecology Research
■ Dr. Chau-Chin Lin 林朝欽博士
Senior Researcher ,Taiwan Forestry Research Institute
Due to developments of information technology and sensor design, it has converged to provide new ways of collecting biodiversity and ecology data at rates that traditional research methodology can not achieve. The new biodiversity and ecology research is evolving into a more interdisciplinary, collaborative and data-intensive science which is a new way of doing science that entails the capture, curation and analysis of massive amounts of data from an array of sources. Ecoinformatics is the latest development following bioinformatics that enables data-intensive research of biodiversity and ecology. It integrates the functions of bioinformatics and provides a framework that enables scientists to generate new knowledge through innovative tools and approaches for discovering, managing, integrating, analyzing data and information. The system of biodiversity and ecological research information management and examples of ecoinforamtics application for Taiwan Ecological Research Network (TERN) are discussed in this talk. Besides, several global, regional networks such as ILTER, GBIF, GEO BON and APBON collaborations of ecoinforamtics activities that connect to TERN’s system are described.

Topic: .A framework for landscape assessment of important Wetlands in Taiwan
■ Prof. Hsing-Juh Lin 林幸助教授
Distinguished Professor & Department Chairman National Chung Hsing University
Wetlands harbor rich biodiversity and biomass and provide a variety of ecosystem services. Therefore, environmental assessment of wetlands is critical for those seeking to manage these pivotal ecosystems. While the landscape development intensity (LDI) index is commonly used for wetlands assessment, it is, unfortunately, limited in scope and, in some regions, efficacy. The objectives of this study were to improve and modify methods for wetlands assessment using a multi-metric approach that incorporated both the LDI index and landscape metrics. We calculated the LDI index values for 10 wetlands across both the area of each wetland and within a 0 to 600 m wide area (in 100-m intervals). The results showed that the LDI index values varied significantly as the buffer distance increased, and specifically, the wetlands plus a 300-m wide swath was found to encompass the most appropriate area of inclusion for assessment. Furthermore, based on the metrics selective criteria, only LDI index and area metrics were incorporated into the assessment schematic. Due to two types of wetlands identified significantly different in the scatter plots of the LDI index and area, the assessment system was built to accommodate appropriate cut-off points. Four levels were then designated; the coastal wetland had an overall accuracy of 70.0% (kappa coefficient of 0.61), while that of the inland wetlands, which included natural and artificial wetlands, was only 41.7% (kappa coefficient of 0.22). This study confirmed that the extent of assessment had an effect on the LDI value, and there were significant differences in the assessment schematics across wetland types. In addition, LDI and/or area indices could be incorporated into landscape assessments. The assessment methods of this study can be applied in regions with high population density and consequently altered terrain, though the metric, scoring ranges, and levels should be adjusted to local conditions.
