2008 ESRI International User Conference to Host a Special Climate Change GIS Program

The upcoming 2008 ESRI International User Conference will play host to over 14,000 attendees and numerous technical and subject-based tracks. One of the new subject threads is the Climate Change GIS track where conference goers can learn about the role of data and technology in investigating and mitigating global warming. Carla Wheeler, ESRI writer, presents an overview of this track:

Melting glaciers and shrinking snow cover. Earlier bird migrations and egg laying. More intense droughts. These signs and others, say the scientists serving on the Intergovernmental Panel on Climate Change (IPCC), point to what they call “unequivocal” global warming.

Today, a growing number of people are heeding the findings of IPCC, which shared the 2007 Nobel Peace Prize with former U.S. vice president Al Gore for raising awareness about man-made climate change and laying a foundation for combating it. Scientists, environmentalists, and others are increasingly focused on studying climate change and its repercussions. (For example, studies that forecast continuing shrinkage of sea ice led the U.S. federal government last month to list polar bears as threatened under the Endangered Species Act.

Grid Computing in Distributed GIS

Guest article by Zahid Imran Ahmed, the Sr. IT Manager of Stesalit Inc.

Some consider this to be the “the third information technology wave” after the Internet and Web, and will be the backbone of the next generation of services and applications that are going to further the research and development of GIS and related areas.

Grid computing allows for the sharing of processing power, enabling the attainment of high performances in computing, management and services. Grid computing, (unlike the conventional supercomputer that does parallel computing by linking multiple processors over a system bus) uses a network of computers to execute a program. The problem of using multiple computers lies in the difficulty of dividing up the tasks among the computers, without having to reference portions of the code being executed on other CPUs.
