provide, through the Internet, a scalable and flexible digital representation
of the nation's geological framework from the map collections of
Canada's geological survey agencies. This will be done from distributed
databases, maintained by individual agencies, that are based on
a common data model, including science language, that makes the
information from mapping published at different scales and to different
geological map database will remain under the control of the
source agency, which will be responsible for updating it regularly.
information, including original citations, must be explicitly
linked to all information in the databases.
data model should respect well-established geological principles
such as the North American Stratigraphic Code, and be compatible
with major "consensual" publications such as the
DNAG volumes and the Lexicon of Canadian Stratigraphy.
data model will accommodate both the original geological information
from the source maps, and common science language and high-level
classifications that will follow international standards and
protocols where available.
data model will support both national "standards"
for a common CGKN portal, and allow flexibility so that individual
agencies can provide information to their own "standards"
directly from their web portals.
Territorial, Provincial and Federal agencies which are actively
involved in the mapping of bedrock geology should be represented
on the sub-group to guide the development of the data model and
its science language, and to populate the geological map databases.
The subgroup will be led by two co-leaders, one representing Federal
agencies and the other, the Provincial and Territorial agencies.
The co-leaders will be appointed by GSC management and the Committee
of Provincial Geologists, respectively.
agency will be responsible for maintaining its own database, including
the provision of the necessary computer systems to support it and
personnel to populate it. Funding will be sought from national programs
such as GeoConnections for support in developing common software
and documentation, and to support travel for regular subgroup meetings
(two per year). Travel support will also be required so that subgroup
members can actively participate in international activities related
to data model development, especially science language.
The subgroup will establish a long-term (3-5 year) plan
to guide the development and maintenance of the national geological
map database. Within this framework, annual plans will be drawn
up to establish the role of each agency in accomplishing particular
tasks, taking into account the agencies' capabilities in terms of
personnel and financial resources for that year. From these annual
plans, projects will be defined to attract matching funding from
The subgroup will meet via conference call regularly
(6-10 times per year), and face to face twice annually. The subgroup
will submit its annual plan to the CGKN secretariat for approval,
and will prepare a written report to the secretariat annually. At
least one member of the Data Infrastructure Coordination subgroup
will be a member of the bedrock subgroup.
