摘要：The fuel driving the engine of growth and sustainable development of any nation is the nation's access to reliable and adequate geospatial information (GI). Over 80% of socio-economic and environmental management decisions are based on quality and accurate information on natural resources and other geospatial data. On the other hand, the roots of under-development of the third world countries, such as Nigeria, emanated from a number of factors which include poor quality data collection, organization and management practices including lack of adequate infrastructure and skilled human capacity to develop the natural resources and manage the environment in a sustainable manner. The consequences of these are: food insecurity, air and water pollution, environmental degradation, etc. This paper therefore, examines in detail the above features in terms of the challenges facing the GI community in Nigeria if the nation must attain rapid sustainable socio-economic development. The significant role of space technology for comprehensive, reliable and real-time geospatial data acquisition and the need for the establishment of a national geospatial data infrastructure (NGDI) are discussed. The paper also presents highlights of the National Geoinformation Policy for Nigeria, focusing on the policy statements, objectives and strategies to enable implementation of the NGDI. The issues addressed in the policy include: geospatial datasets, standards, metadata, legal, data access and data security, organizational framework, commercial, capacity building, and related national policies and international cooperation. A focused implementation of the policy items is expected to facilitate efficient production, management, dissemination and use of geospatial information for national development
