Why an Exchange Network?
Many environmental problems cross jurisdictions and involve a
web of natural systems that interact with human communities in
The business of managing and solving these problems has
become highly information intensive.
Environmental policy makers and other stakeholders need
access to timely, accurate, and consistent data that present a
holistic picture of the environment.
Exchanging high quality information allows governments,
regulated communities, interest groups, and the public to make
better decisions regarding the environment.
Electronic data sharing between agencies is often mistaken for
a simple automatic process; however, the truth is that many of
these systems are innately incompatible with each other.
