This working group plus the Chair of the International Association of Geodesy, sub commission on Reference Frames, Africa (SC 1.3d), constitutes the International Steering Committee on AFREF (ISCA).


AFREF achievement since CODIST.1 (2009):

The Steering Committee held one meeting during the reporting period. The meeting was held in n Addis Ababa, Ethiopia. The main activities during the reporting period were creating awareness and requesting organizations to join the AFREF project, technical workshops and preparation of technical documents for the implementation of AFREF.

workshops and training
Workshops and Training

Two training sessions of two weeks duration on AFREF and GNSS data processing were held at Regional Centre for Mapping of Resources for Development (RCMRD), Kenya in August 2009 and August 2010.

Objectives to equip geodesist with practical skills in the establishment and operation of Continuous Operating Reference Stations.

The topics discussed included AFREF implementation strategy, IGS products & data, hardware and software requirements to establish Continuous Operating Reference Stations, design of geodetic networks and GNSS data processing.

Participants from eleven countries namely; Botswana, Ethiopia, Namibia, Malawi, Kenya, Uganda, Nigeria, Sudan, South Africa, Tanzania and Zambia took part in the courses.

Two expert group meetings were held in Nigeria and Ethiopia in 2010 and 2011 respectively.

Presentations on AFREF were made at: IGS 2010 conference; EUG 2009 conference, IAG 2009 conference, REFAG conference in 2010, and Africa Array meetings held in South Africa and USA in November and June 2010 respectively.

website and newsletter
Website and Newsletter

The AFREF website was created in May 2006 ( UNECA continues to maintain and update the website. All papers and presentations relating to AFREF and the CFP are available on the site.

The quarterly AFREF newsletter continued to be published regularly by the AFREF secretariat at RCMRD. The objective of the newsletter is to create a forum for discussions and exchange of information and experiences in the implementation of AFREF project.

Five editions of the Newsletter were published during the reporting period as follows: Three editions in 2009 and two in 2010.

implementation status
Implementation Status

The following countries have already established at least one Continuous Operation GNSS Reference Stations (CORS); Algeria, Egypt, Mozambique, Ghana, Kenya, Benin, Morocco, South Africa, Namibia, Zambia, Ivory Coast, Uganda, Malawi, Ethiopia, Mozambique, Nigeria, Mauritius, Tanzania, Cameroon. Algeria, Ethiopia, Egypt, South Africa, Nigeria, Ghana and Benin.

AFREF Operational Data Centre (ODC) for the collection and dissemination of data from permanent GNSS stations in Africa started operations at the beginning of June 2010.

GNSS data from all known stations that provide data on an open and free basis to users is collected and archived in the ODC which means that there is now one data base from which users can retrieve data.

At present there are about 50 stations throughout Africa that contribute to the ODC The web address for the AFREF ODC is:

The ODC is operated by Chief Directorate: National Geospatial Information of the Republic of South Africa.

implementation status12
Implementation Status

The next phase is to densify the CORS and realize the Africa Reference Frame that can be adapted by African Countries.

A draft call for participation document to all interested and capable institutions in the processing and analysis of GNSS data from the network of permanent GNSS base stations in Africa for the establishment of a uniform geodetic reference frame has been prepared.

This document together with the methodologies and strategies for computing the Africa Reference Frame will be discussed during the present CODIST meeting.

An implementation support plan for the AFREF project was endorsed for support by the AU-EC 8th Priority Action and Joint Strategy.

Projects in progress

Current progress:

Outline of document – complete

Description of content of each chapter – complete, but amendments can be effected

Document specification - complete

Production schedule – draft

Funding sourced – project proposal for funding in progress

Assignment to authors/contributors – awaiting funding.

Funding for this project is now the biggest obstacle to making progress. It is estimated that US$ 120,000 will be required. This estimate is based on authors only being paid an honorarium fee.

cooperation with the ica
Cooperation with the ICA

The Working Group has a very close working relationship with the International Cartographic Association (ICA), in particular the ICA Working Group on Mapping Africa for Africa.

The ICA adopted the Durban Statement on Mapping Africa for Africa in August 2003 and since that time has been providing international experience and expertise to the initiative.

It has supported the WG on Fundamental Datasets with valuable advice.

working group on standards
Working Group on Standards

Compiled by Sives Govender, Executive Director, EIS-AFRICA and Antony Cooper, Operating Unit Fellow, CSIR (South Africa)

The activities are focused on:

Participation in international standards activities (ISO TC 211)

Key standards for future consideration support the development of Fundamental Geospatial datasets and the Mapping Africa for Africa Initiative (MAfA).

ISO TC 211 plenary in Pretoria in November 2011.

african metadata tools
African Metadata tools

At CODI V a African profile of ISO 19115 created.

Tools assessed.

UNECA tested and deployed GeoNetwork Opensource.

UNECA used this FOSS tool to deliver short courses in Sierra Leone on metadata creation, dissemination and discovery.

We must consider this tool to support the capture of the African metadata profile.


This reports details the activities undertaken by Mr. Antony Cooper in his role as Standard Working Group member and Liason from ISO/TC211 to UNECA. It covers the period from the end of CODIST1 to present.

participation in international standards activities
Participation in international standards activities

ISO/TC 211 is the International Organization for Standardization’s Technical Committee developing standards for Geographic Information/Geomatics (see: ISO/TC 211 was established in 1994 and is a very active committee, with 32 Participating Members (P-members) and 31 Observing Members (O-members).

Currently, the ISO/TC 211 members from Africa are:

 P-members: Morocco and South Africa.

O-members: Kenya, Mauritius, Swaziland (corresponding member), Tanzania and Zimbabwe.

South African is only active African country. (SABS SC71E).

ISO/TC 211 also has 31 Class A Liaisons – these are international organizations that also participate in ISO/TC 211. They include agencies of the United Nations, international scientific unions and industry organizations. UN ECA became a Class A Liaison in 2005.

Currently Mr. Andre Nonguierma and Mr. Antony Cooper, are the liaison from UNECA to ISO/TC 211.

ISO/TC 211 Plenary in South Africa

South Africa hosted the 10th Plenary in March 2000 and South Africa will host the 33rd Plenary in Pretoria from Sunday 13 to Friday 18 November 2011,

Essential that there is good participation African countries, either as part of their national delegation, or for those countries that are not yet members of ISO/TC 211, through the United Nations Economic Commission for Africa (UN ECA) or other liaison organizations.

how do you participate
How do you participate?

For experts from the members of ISO/TC 211, namely Kenya, Mauritius, Morocco, South Africa, Swaziland, Tanzania and Zimbabwe, participation can be through your national standards body. (The relevant contact details will be provided).

As part of the delegation from UN ECA, as it is a liaison organization to ISO/TC 211. ECA must forward names to ISO.

Through other liaison organizations to ISO/TC 211, such as the Global Spatial Data Infrastructure (GSDI), the International Cartographic Association (ICA), the International Society for Photogrammetry and Remote Sensing (ISPRS), or the International Steering Committee for Global Mapping (ISCGM).

how do you participate30
How do you participate?

There are no fees.

delegates obviously need to cover their subsistence and travel costs.

Typically, there are two deadlines for meetings of ISO/TC 211:

By 13 August 2011, ISO/TC 211 needs to know which member countries and liaisons will participate, and approximately how many delegates there will be.

By 13 October 2011, ISO/TC 211 needs to know the names of all the delegates, and hence the exact number of attendees.


CODIST GEO members must exploit the opportunity of having the ISO/TC 211 experts in Pretoria.

We must plan to have events such as tutorials or workshops on specific standards, which would be open to anyone.

ISO/TC 211 also holds tutorials or workshops on ISO processes, the ISO Directives, the ISO/TC 211 scope, the unified modeling language (UML) as used in ISO/TC 211, and terminology in ISO/TC 211 standards.

Participation can only enhance our understanding and contribution to developing our own national standards.


For the Working Group on Standards to realistically deliver on its mandate it is imperative that dedicated funding be sourced to cover the costs in attending Standards meeting as well as to develop African profiles of the ISO standards to support FDS and MAfA.

The WG on Standards need more volunteers to join the Standards WG.

We must participate in ISO TC 211 in South Africa and UNECA must assist with this process.

Implementation agency/Custodians must be NMAs

NMAs must take a leadership role.



Best Practise guideline will need significant funding and also “our” regular inputs to keep document “alive”.


Complex, technical

Need dedicated resources to develop African profiles to assist Mapping Africa for Africa.

Must attend ISO TC 211 plenary in South Africa.

Capacity Building:

Resourcing important

Co-locate events at AfricaGIS and AARSE (save costs and maximise exposure)
