COMMISSION
X:
"GLOBAL
AND REGIONAL GEODETIC NETWORKS"
Introduction
The
goal of the Commission is to focus on the variety of existing control
networks (horizontal or vertical, national or continental, global from
space techniques) as well as their connections and evolutions.
The
Commission has two types of subdivisions: Sub-Commissions and Working
Groups:
1)
Sub-Commissions for large geographic areas: Europe, North
America, South America, Africa, South East Asia and Pacific. Such
Sub-Commissions will deal with all types of networks (horizontal,
vertical and three-dimensional), and all related projects which belong
to that geographical area.
2)
Working Groups for specific technical topics which would be
relevant to the Commission's activities. Such Working Groups are not
substitutes for a SSG of the IAG, but rather look at technical and
practical problems, in particular by establishing specifications for
the countries, and also possibly sponsoring training seminars.
In
addition, Commission X has a Steering Committee (SC) consisting of:
·
President
of the Commission
·
Presidents
of the Sub-commissions
·
Chairs
of the Working Groups
Each
country member of the IAG is permitted to appoint one representative
to Commission X. If the country belongs to an area where a
Sub-Commission has been already established, the representative will
be a de facto member of that Sub-Commission. Each country not yet a
full member of the IAG is welcomed to appoint an observer to the
Commission. Members of Working Groups will be selected by the Chairs,
and approved by the SC after consultation with relevant people and
representatives of countries. The web site for the Commission is at: http://lareg.ensg.ign.fr/GRGN/.
Objectives
of the Commission
1.
To expand the present GRGN web site in order to give a proper
source of information of relevant activities, including
Sub-Commissions and Working Groups, but also related activities at
national or international level, such as survey agencies,
international programs or projects, services such as IGS, IERS or
others. This site should also provide informations on standards and
terminology, catalogue of datums and cartographic coordinate systems.
2.
To expand the list of national representatives and involve them
more in the Commission activities (for instance updates of the web
system).
3.
To stimulate the formation of new Sub-Commissions.
4.
To update the list and charters of the Working Groups.
5.
To stimulate the development of a modern geodetic framework for
Africa (AFREF).
6.
To stimulate the organisation of a training school related to
the GRGN field (modern networks, ITRF, GPS, etc.).
7.
To promote ITRF as the international framework, and to realise
its densification for all type of uses, help to remove
misunderstandings with respect to WGS84, and promote ITRF for the new
global navigation satellite systems such as the European Galileo
program.
