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.
