Program Information
Introduction
The NSF Special Report on Cyberinfrastructure states,
[E]nvironments and organizations, enabled by cyberinfrastructure,
are increasingly required to address national and global priorities,
such as understanding global climate change, protecting our natural
environment, applying genomics-proteomics to human health,
maintaining national security, mastering the world of nanotechnology,
and predicting and protecting against natural and human disasters,
as well as to address some of our most fundamental intellectual
questions such as the formation of the universe and the fundamental
character of matter.
That's how the NSF Blue Ribbon Advisory Committee in their report,
Revolutionizing Science and Engineering Through Cyberinfrastructure,
summarized the scientific need for cyberinfrastructure. The new
capabilities are 'essential, not optional, to the aspirations of
research communities,' the report states.
(full NSF Special Report available at:
http://www.nsf.gov/news/special_reports/cyber/essential.jsp).
Indeed, the demand for cyberinfrastructure has come from research
communities that recognize the many ways it will allow them to push
the scientific envelope. While Geoscience has been one of the early
adopters of information technology (IT), there is the potential for
greater adoption of modern IT approaches and a corresponding need
for training in this field.
The Cyberinfrastructure Summer Institute for Geoscientists (CSIG) has
been designed to provide such training, with the goal of improving the
understanding of IT concepts among geoscientists and familiarizing
graduates students and researchers with new IT tools. CSIG 2005 builds
upon the successful first CSIG offering in August 2004
(http://www.geongrid.org/CSIG04/program_info.html).
The week-long curriculum is focused on IT topics that serve the
immediate science goals of the community. The format provides a quick
introduction to key IT topics with some hands-on exercises. The overall
course structure is as follows. The topic for Day 1 is Data Modeling,
with emphasis on scientific data. Day 2 will introduce the concept of Web
Services with hands-on exercises, and also provide an introduction to Grid
Services. Day 3 will cover GIS concepts and software and will discuss Web
services-based standards for GIS information. Day 4 will discuss issues
related to data integration and map integration, including advanced concepts
such as semantic data integration using ontologies. There will be a
discussion of technologies related to Data Registration, Ontology-based Search,
and Data Integration. Finally, Day 5 will provide an introduction to scientific
workflow systems and their role in scientific analysis and collaboration.
The goal of the CSIG is to provide geoscientists an "IT headstart", and to
expand the community of IT users in earth science research.
