National Data Centers (NDCs) are evolving both technically and in the
breadth of their application to subsurface resources. Having grown
from National Data Repositories (NDRs) in the 1990s, NDCs offer a
centralized, consolidated means of leveraging data about any asset of
importance to a government or region. Rather than a purely technical
description of the evolution of the NDC, this paper casts the technical
capabilities of the NDC in terms of key sources of value.
Emerging Web-based technologies are
also discussed in terms of enabling
new services and business models
for the NDC.
