Achievement
  • AFREF achievement since CODI V (2007)

9
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 2007 and
    August 2008.
  • Objective to equip geodesist with practical
    skills in the establishment and operation of
    Continuous Operating Reference Stations.
  • Participants from nine countries Ethiopia,
    Malawi, Kenya, Uganda, Nigeria, Niger, South
    Africa, Tanzania and Zambia.
  • Presentations on AFREF were made during
  • AARSE conference held in Ghana in October 2008
  • The International Symposium on GNSS, Space-Based
    and Ground-Based Augmentation Systems and
    Applications held in Germany, November 2008
  • Africa Array meeting held in South Africa June
    2008
  • Trimble Dimensions conference held in November
    2007 in the USA.

10
Website and Newsletter
  • The AFREF website was created in May 2006
    (http//geoinfo.uneca.org/afref). 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. Six editions of the Newsletter
    were published during the reporting period as
    follows Two editions in 2007, three editions in
    2008 and one in 2009.

11
Implementation Plan
  • An implementation plan for the AFREF project was
    completed and sent to donors for funding.
  • The proposal was endorsed for support by the
    AU-EC 8th Priority Action and Joint Strategy.
    Implementation is expected to start in the next
    year. The main goals associated with the project
    are to
  • Establish a network of permanent GPS reference
    stations that will define the African Reference
    Frame for practitioners to use for position
    determination, and forming part of the global
    geodetic infrastgructure. The stations will
    conform to IGS standards, continuously collecting
    data and transmitting same to relevant data
    processing centres.
  • Establish a network of regional data processing
    centres to receive data from stations in their
    respective regions, process them and transmit the
    processed data to a designated main data
    processing and archiving facility.
  • Establish a data archiving and dissemination
    facility to compute parameters for the African
    reference frame and disseminate same continuously
    to users.
  • Compute the parameters of the African Reference
    Frame.
  • Support Countries to align national coordinate
    systems. to AFREF
  • Establish a network of Geodesists sharing lessons
    and working together to realize the objectives of
    the AFREF project, extend and densify the
    network, and continuously compute and disseminate
    improvements and corrections to the parameters of
    the African reference frame.

12
Implementation Status
  • The demonstration phase of AFREF has started in
    2007.
  • The objective of this phase is to show the
    installation, operation, data dissemination and
    analysis capabilities.
  • 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.
  • Two CORS were donated by Leica Geosystems and
    were installed in Kenya and Nigeria.
  • Trimble Navigations donated five CORS and have
    been installed in Tanzania, Niger, DRCongo and
    Ethiopia.
  • Some data from the established CORS is already
    being received by HartRAO data Centre in South
    Africa and the International GNSS Service (IGS).
  • The next phase is to densify the CORS and
    realize the Africa Reference Frame that can be
    adapted by African Countries.
  • Methodologies and strategies for computing the
    Africa Reference Frame were discussed during the
    pre-CODIST Workshop on AFREF Implementation Plan.

13
AFREF Workshop Outcomes
  • Held on 28 April 2009
  • Recommendations will be presented by Chair of WG
    at a later session.

14
Working Group on Fundamental Datasets
  • Compiled by Dr. D. Clarke, Chief Director CDSM
    (South Africa)
  • The activities are focused on
  • Capacity Building Workshops and Training
  • Implementation Plan
  • Implementation Status

15
Catalogue of Fundamental Geospatial Datasets
  • At the previous CODI-Geo meeting held in April
    2007 the WG on Fundamental Datasets submitted a
    draft report on the Catalogue of Fundamental
    Geo-spatial Datasets for Africa.
  • It was requested that comments be provided on the
    draft report.
  • No subsequent comments were received

16
Meetings and Collaboration
  • The WG held a joint meeting with the ICA WG on
    Mapping Africa for Africa on 27 August 2008, in
    Cape Town. At this meeting
  • The report on the Catalogue of Fundamental
    Geo-spatial Datasets for Africa was reviewed and
    approved.
  • The catalogue of fundamental geo-spatial datasets
    had been loaded on the geo-portal of UNECA. But
    the UNECA geo-portal was not working.
  • It was decided that the Country Gap Analysis
    reports, should be sent out to each country.
  • The next phase of work in terms of the project
    plan, namely the best practices guidelines,
    should be commenced. The first task will be to
    describe the framework for the guideline

17
Next Steps
  • Guidelines of Best Practice
  • In an effort to start the process of defining
    what the content of the Guidelines of Best
    Practice should be, an assessment of the various
    challenges facing countries in the acquisition,
    maintenance and dissemination of fundamental
    geo-spatial datasets was undertaken. A
    questionnaire survey was used for this purpose.
    The initial response to the questionnaire was
    very low and no significant results can be drawn
    from the responses. The questionnaire was
    circulated to all African mapping organizations
    and through the Global Spatial Data
    Infrastructure. It is hoped that further
    responses will be obtained during this CODIST-Geo
    meeting.
  • A draft (1.2) of the contents of the Guidelines
    of Best Practice has been prepared and will be
    presented for discussion and comments during
    CODIST Geo.
  • The WG on Fundamental Datasets and the ICAs WG
    on Mapping Africa for Africa continue to work
    well together, having joint meetings whenever
    possible.
  • The following meeting to take place in November
    in Santiago, Chile coinciding with the ICAs
    International Cartographic Conference.

18
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
  • African metadata profile of ISO 19115
  • 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).

19
African metadata profile of ISO 19115
  • The starting point for the African metadata
    profile is the set of core metadata elements in
    ISO 19115, whether they are mandatory,
    conditional or optional. All the entities in the
    core have been unraveled to identify what the
    actual metadata elements were.
  • These core metadata elements have been included
    in a matrix to illustrate the structure of the
    core (this matrix is attached to full report).
  • All the metadata elements in the matrix have been
    illustrated using the metadata for South Africa's
    150 000 national mapping series, as the metadata
    was readily available, provided metadata for most
    of the metadata elements (there was not metadata
    for some of the optional elements), and was for
    an African dataset series that should be familiar
    to most geo-information experts in Africa.. (this
    document as been attached to full report)

20
Metadata tools
  • A review committee was formed during CODI V to
    evaluate tools currently available for compiling
    and viewing metadata, with the aim of having an
    open source tool readily available that supports
    the African metadata profile.
  • UN ECA has acquired, tested and deployed
    GeoNetwork opensource, a standards-based, free
    and open source catalogue application developed
    initially by FAO.
  • It provides metadata editing and search
    functions, and an embedded interactive web map
    viewer.
  • GeoNetwork opensource provides a decentralized
    environment enabling access to geo-referenced
    data bases, cartographic products and related
    metadata from a variety of sources.
  • See http//geonetwork-opensource.org/
  • UN ECA has used GeoNetwork opensource to deliver
    a short course in Sierra Leone on metadata
    creation, dissemination and discovery.
  • However, more experience is required with
    GeoNetwork opensource before definitively
    recommending it as a suitable metadata tool for
    Member States.
  • As GeoNetwork opensource supports ISO 19115, it
    will support the African metadata profile of ISO
    19115.
  • However, GeoNetwork opensource will not yet have
    a template that will allow the user to restrict
    the metadata fields they see to just those of the
    African metadata profile of ISO 19115.

21
Participation in international standards
activities
  • ISO/TC 211
  • The Technical Committee within the International
    Organization for Standardization (ISO) developing
    standards for geographical information, in the
    ISO 19100 series.
  • ISO/TC 211 has published 29 International
    Standards, 5 Technical Specifications and 3
    Technical Reports. It also has 16 active
    projects developing new standards or
    specifications, and a further 7 amending or
    revising existing standards and specifications.
  • ISO/TC 211 is a very active committee, with 31
    Participating Members (P-members) and 31
    Observing Members (O-members).
  • Members from Africa are
  • P-members Morocco and South Africa.
  • O-members Kenya, Mauritius, Tanzania and
    Zimbabwe.
  • South Africa has been the only active African
    country participating in ISO/TC 211, attending
    all the Plenaries since 1998 (with over 25
    delegates over the years), contributing to the
    development of standards.
  • ISO/TC 211 also has 28 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.
  • The United Nations Economic Commission for Africa
    (UN ECA) became a Class A Liaison in 2005. The
    current liaisons from UN ECA are Chukwudozie
    Ezigbalike, Paul Belanger, and Antony Cooper.
  • ISO/TC 211 meetings enjoy very good participation
    and hopefully, participation by African experts
    will increase in the near future. The 28th
    Plenary of ISO/TC 211 is scheduled for Molde,
    Norway, on 28 and 29 May 2009.

22
Key standards for future consideration support
the development of Fundamental Datasets and
(MAfA)
  • ISO/TC 211 has begun developing standards for
    application domains, which will touch directly on
    the work of users, as these standards deal more
    with data issues than system issues.
  • In considering the fundamental data sets for
    Africa, the following are key standards
  • The Metadata The best known ISO/TC 211 standard
    is ISO 191152003, Geographic information
    Metadata
  • Quality There are three standards from ISO/TC
    211 dealing with quality ISO 19113 2002,
    Geographic information Quality principles, ISO
    191142003, Geographic information Quality
    evaluation procedures, and ISO/TS 191382006,
    Geographic information Data quality measures.
  • Cataloguing or classification The two relevant
    standards are ISO 191102005, Geographic
    information Methodology for feature
    cataloguing, and ISO 19126, Geographic
    information Feature concept dictionaries and
    registers
  • Essential climate variables (ECVs) ISO 19144-1,
    Geographic information Classification systems
    Part 1 Classification system structure. ISO
    19144-2, Geographic information Classification
    Systems Part 2 Land Cover Classification
    System LCCS.
  • Land administration A new ISO/TC 211 project is
    ISO 19152, Geographic information Land
    Administration Domain Model (LADM), which is
    developing common terminology and a framework
    model for land administration, bridging the
    cadastre, deeds, land ownership and land tenure,
    both formal and informal.

23
Outlook
  • 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 will work closely with the WG
    on FDS to look at priority standards and
    profiling these for Africa.
  • The WG on Standards need more volunteers to join
    the Standards WG.
  • South Africa is considering hosting ISO TC 211 in
    the second half of 2010.
