4. Future research opportunities in the geosciences will be
significantly affected both by the availability and utilization of
Information Technology. Understanding the rock record that
preserves ~4.5 billion years of history, Earth structure, and
the processes at work is the key to answering scientific
questions associated with studies of biodiversity, climate
change, planetary processes, natural resources and
hazards, and the 4-D architecture and evolution of
continents. It has become evident that we can only answer
these complex questions through the integrationintegration of all the
data we have at hand and that this will require the
application of modern IT toolsapplication of modern IT tools.

5. What is Geoinformatics?
Geoinformatics is a science which develops and uses information science
infrastructure to address the problems of geosciences and related
branches of engineering.
The three main tasks of geoinformatics are:
･ development and management of databases of geodata
･ analysis and modeling of geodata
･ development and integration of computer tools and software for the first
two tasks.
Geoinformatics is related to geocomputation and to the development and
use of geographic information systems or Spatial Decision Support
Systems
Applications ･ An object-relational database (ORD) or object-relational
database management system (ORDBMS) Object-relational mapping (or
O/RM) Geostatistics

8. Data SetData Set: A relatively raw compilation of data
(standards, formats, completeness may be questionable)
Data BaseData Base: A mature data compilation that has been
“cleaned”, standardized with input from the scientific
community, formatted for use by others (independent of
proprietary software, e.g., ORACLE)
Data SystemData System: A linked and organized set of data bases
including public domain software (not platform dependent),
tutorials, workflows, and procedures to analyze the data

10. •The Geosciences are a discipline that is strongly data drivenstrongly data driven,
and large data sets are often developed by researchers and
government agencies.
•The complexity of the fundamental scientific questions being
addressed require a variety of data with highly integrative andhighly integrative and
innovative approachesinnovative approaches if we are to find solutions.
•Geoscientists have a tradition of sharing of datatradition of sharing of data, but being
willing to share data if asked or even maintaining an obscure
website accomplishes little. Also as a community, we have
no mechanisms to share the work that has been done when a
third party cleans up, reorganizes or embellishes an existing
database.
•We waste a large amount of human capitalwaste a large amount of human capital in duplicative
efforts and fall further behind by having no mechanism for
existing databases to grow and evolve via community input.
