2 Geoinformatics The application of advanced information technologies to build a distributed, integrated digital information system and working environment that provides innovative means for the study of Earth as a complex system. GSA-SC, 3/17/2009 K. Lehnert: Supporting Science & Education with Geoinformatics 1 www.geoinformatics.info AGU: ESSI Focus Group GSA: Geoinformatics Division EGU: ESSI Section

3 Drivers of Geoinformatics The need to handle an ever-increasing volume of Earth and space observation data. The need to discover, access, integrate, and understand multi-disciplinary data in order to deal with more complex problems and respond more rapidly. The need for processing power, storage, network bandwidth, and analysis tools to support data-based and data-intensive science. GSA-SC, 3/17/2009 K.

29 Concluding Remarks GI is necessary to support Geoscience research & education. While the number of GI systems is growing, coordination and integration of systems is insufficient. Open access to scientific data is fundamental. Organizational and cultural challenges need to be addressed to make GI a real science infrastructure. Scientists and educators need to actively participate in the development of GI. GSA-SC, 3/17/2009 K. Lehnert: Supporting Science & Education with Geoinformatics 28

30 What can be done Data Managers ▫ Enhance available resources (digital lab book, convenient data submission ▫ Education & outreach Scientists ▫ Recognize the need of and comply with data policies ▫ Engage in dialog with data managers ▫ Support funding of new ‘coordinated’ database initiatives Societies ▫ Improve visibility of DATA issues ▫ Facilitate the global dialog on data issues Agencies ▫ Provide incentives for data sharing ▫ Encourage & support collaboration among databases (nationally & internationally) GSA-SC, 3/17/2009 K.
