1 REGIONAL CENTRE FOR TRAINING IN AEROSPACE SURVEYS (RECTAS) Department of Geographic Information Science Curriculum for Master of Science in Geographic Information Science (M.Sc. GIS) October 2014

2 The programme The M.SC in Geographic Information Science is offered by the Department of Geographic Information Science, Regional Centre for Training in Aerospace Surveys (RECTAS) Ile-Ife, Nigeria. The duration is 3 semesters of 17 weeks each within 18 months. Programme Philosophy The Master s degree programme in in Geographic Information Science (M.Sc. GIS) is designed to train highly skilled manpower in the science and technology of geospatial information. The Programme is designed to extend the frontiers of education and scientific research in Geographic Information System (GIS) with a view to increasing the benefits derived from the technology in various disciplines. In addition, the Programme is expected to provide opportunity for networking among several countries who are member States of RECTAS in particular and other nations in general. The graduates of the programme will fit into the critical areas of their country s economy. Programme Objectives The objectives of the Programme are to: a. provide theoretical and practical training in Geoinformatics and applications; b. produce high grade professional experts/scientists in Geoinformation science; c. enhance capacity and capability for research development and application of Geographic Information technologies; d. equip graduates of various disciplines with adequate technical capability in Geoinformation science applications; e. provide opportunities for result-oriented research in Geographic Information System (GIS), relevant to the country s needs of the participant; f. disseminate to the public the results of research and facilitate the practical application of these results; and g. collaborate with national and international agencies in the areas of applying GIS to tackle relevant problems. 2

3 Justification for the Programme Geoinformation Technology is an emerging area of specialization that is required in the identification, assessment and management of land and natural resources. Therefore there is the need have access to such knowledge in order to use it in developing and managing the abundant resources available to African countries. In particular, land is a fundamental resource for all human uses desiring proper management for a sustained productivity; and this has been the source of many feuds in Africa. Proper understanding of the availability and disposition of natural resources (including renewable and non-renewable energy resources such as oil and natural gas) can be achieved through Geoinformation Technology; hence it will enhance their exploitation for the economic benefit of the nation s citizens, and with adequate consideration for the environment. Secondly, natural and man-induced disasters like earthquakes, volcanic eruptions, landslides and tsunamis have been known to wreak havoc on human habitation, particularly in Africa where there is paucity of knowledge in strategies for their management. Injudicious oil and mineral exploitation, uncontrolled deforestation with the attendant climate change effects of ozone depletion, global warming and other atmospheric issues are challenges facing the world. Therefore, an understanding of such occurrences and their spatial distribution will enable proper management of their manifestations and post-occurrence activities with minimal effects on the population. Finally, any nation s integrity borders on its capabilities in crime prevention and maintenance of peace and security within the country. Therefore, police and military intelligence gathering through Geoinformation Technology are essential in this regard, hence the need to equip their personnel through their exposure to this programme.
