8Achievement
- AFREF achievement since CODI V (2007)
9Workshops 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.
10Website 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.
11Implementation 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.
12Implementation 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.
13AFREF Workshop Outcomes
- Held on 28 April 2009
- Recommendations will be presented by Chair of WG
at a later session.
14Working 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
15Catalogue 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
16Meetings 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
17Next 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.
18Working 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).
19African 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)
20Metadata 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.
21Participation 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.
22Key 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.
23Outlook
- 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.
