geodetic control network as a pre-cursor of an effective
NGDI. Furthermore, the existing analogue 1:50000
topographic map series of the country are being converted to
digital format.
* The custodian shall keep the dataset(s) it produced while
making the metadata available to the NGDI clearinghouse.
» Develop geospatial data standards for the NGDI, which shall
strive to conform to the ISO standards.
e Facilitate the creation of prelintinary standard services to help
users understand and apply standards, at the initial stage of
NGDI development and promote the benefits of using the
NGDI supported standards.
e Define the metadata content and structure for the NGDI and
produce detailed metadata implementation guidelines,
including practical advice on maintenance and use of
metadata
* Establish Clearinghouses in the NGDI node agencies and
enter the certified metadata of data producers.
e Facilitate adoption and legalisation of all agreements and
protocols relating to NGDI operations.
* Put in place high-speed and high-bandwidth backbone carrier
in the apex clearinghouse as the main gateway and master
server and implement a database server at each NGDI node
agency.
* Promote submission and early passage of the bill to establish
NGDI, which shall include the policy items and funding.
« Encourage indigenous personnel with relevant skills in
acquisition and analysis of GI in the country by ensuring that
all GI related projects are locally implemented to a minimum
of 75%.
e Put in place modalities to ensure that GI producers give
evidence of local contents of their production activities.
* Promote synergy among Gl-related policies.
e Liaise with Federal Ministry of Environment and the
Department of Petroleum Resources to implement
compulsory geo-referenced data requirements for EIA and
ESI.
* Ensure adequate fiscal provisions and funding of the NGDI.
4.0 CONCLUSIONS
In the foregoing sections, the development of GI in Nigeria has
been discussed with main focus on the national space
programmes, geospatial information policy as well as the
implementation of the National Geospatial Data Infrastructure.
The new NigeriaSat-1 earth observation satellite has generated
much interest at all levels and in all sectors in the country
adding impetus to the decision of government to launch a
communication satellite in 2006. The national GI policy as an
essential backbone for efficient realisation of the NGDI has
been prepared and submitted to government for approval; the
policy is expected to facilitate respect and trust among all
stakeholders, apart from its other benefits. With the medium
resolution saiellite already in place, when NGDI with the
sustaining policy are properly implemented in the country, the
essential GI will consequently become part of the national
infrastructure that will facilitate a rapid improvement of the
national economy including an efficient management of the
nation’s natural resources and environment.
