Objective 1 Implementation of the Terrestrial
Reference Frame for the North Africa region
by

• To inventory all the geodetic data available in
  this area,
• To carry out the complementary GPS measures on
  the six countries
• To install permanent Stations GPS
• To proceed to the treatments (data processing)

18
Objective 2 Determination of the local Geoid on
the région

• To inventory the Gravimetric data available in
  this area,
• To carry out the complementary gravimetric
  measures on the six countries
• To install absolute gravimetric stations
• To proceed to the whole treatments

19
Objective 3 Putting in place the Institutionnal
Framework for implementing NAFREF Project

• Implication of the institutions of the states
  for resources
• Implication of the African and extra African
  specialists on the scientist and technical level
• Project coordination by AOCRS

20
Three Workshops to prepare the implementation
of this Project

• In Tunis, May 2000
• In Algiers, may 2001
• In Rabat, September 2003

21
Participants to Workshops Participating
Countries

• And The representatives of the International
  Association of Geodesy, of the BGI, EUREF
  Project , SIRGAS Project, France and Poland took
  part in work of these workshops.

22
Tree working groups activate under the
coordination of AOCRS

• Mission of Group 1 to carry out the tasks
  listed in the objective n1
• Mission of Group 2 to carry out the tasks
  listed in the objective n2
• Mission of Group 3 to carry out the tasks
  listed in the objective n3

23
1. The group 1 one and 2 work o on the data
inventory 2. The group 3 works on the technical
spécifications and normalisation
24
Data Inventory

• A) By Inventory, it is understood
• The selection of the existing data
• The reprocessing and
• To put the data under digital form

25
The national cartographic institutions works on
the inventory, especially on the classic
networks, Samples

C) Evaluation and statistically selection of
the data
31
The results of the data inventory phase were
presented During the third workshop (2003) -
Rabat, Morocco.
32
NEXT STEPS

• The three working groups are expected to bring
  their work
• The next workshop will be organized
• The first GPS permanent stations will be
  installed in Algeria and Mauritania
