f LINC
The Target Version of LINC incorporates all the
elements required to meet client requirements.
This includes: on-line access to all SMRSS digital
geomatics data; seamless and feature based
queries; visualization for most data types, and; a
Canada wide client base.
Initially a Baseline Version will be developed in
order to meet immediate client needs. This system
will consider only a subset of the SMRSS resource
holdings and required functionality in order to be
timely.
Major Clients
Initial clients of the system will be clients internal
to SMRSS who use other SMRSS data as part of
their operations. Access to LINC will also be
provided to internal digital distributors who would
use the system to access, retrieve and forward the
data through off-line methods (or other methods
presently in use by those organizations) to their
clients. Specifically, the Digital Distribution
Office of the Products and Services Division
would have this access.
In order to have the external clients' perspective
and verify the system's performance over a WAN,
the Baseline System will be accessible in certain
organizations with existing spatial data
infrastructures. This would allow those
organizations to better use the baseline system and
provide valuable feedback on its adequacy and
potential problems that are network related.
4. LINC COMPONENTS
Information Management Framework
The Information Management Framework (IMF)
is the set of policies and standards that provide a
frame or context within which the Geomatics
Information Infrastructure (GII) will operate.
Together the IMF and GII form the Land
Information Network for Canada (LINC), and
both are equally important to the success of LINC.
Technology is not the only issue impacting on the
effectiveness of information management within
the Sector. The development and the adoption of
standards also plays a crucial role. Useful and
well integrated off-the-shelf and custom products
will be accessed through the GII with confidence
225
because of the use of a basic set of management
principles. These principles, in turn, will help
SMRSS meet its mandate in a more effective
manner through the use of support policies and
standards. This collection of policies and
standards and the principles and mechanisms that
will be required to develop and maintain them is
referred to as the Information Management
Framework. It is the responsibility of SMRSS to
decide on and to act upon the IMF.
Policies and standards in the context of the IMF
can be further broken down as follows:
Policies
- organization
- acquisition, use, dissemination, security
and access control of data
- systems and applications
- pricing and intellectual property for
products and services
Standards
= recognized standards for data exchange
and modelling
= data communication, storage, description
and administration
= geomatics data integration models
(spatial and non-spatial)
= tool development and operation
Geomatics Information Infrastructure
The mission of the Geomatics Information
Infrastructure system is to facilitate the
production, exchange and integration of geomatics
information so as to improve the internal
efficiency of SMRSS and provide better external
access to its products and services.
General requirements for the GII are:
- a meta-data catalogue describing the data
sets and tool sets available via the GIT, as
well as data production and quality
information;
- interfaces to a series of data holdings to
allow the retrieval of data sets;
= user access facilities to allow users to
identify, order and receive requested data
sets;
- system management and accounting
services;
- graphical services to order both digital
