Introduction & Background • GIS technology are increasing being used by a myraid of organizations across the world in both the private and public sectors. • This exponential demand challenges university researchers and academics to evaluate their GIS infrastructural requisites at both the graduate & postgraduate scale. • Administrators & those not directly connected with using the facility are of the view that a GIS Laboratory is self-sustaining.
Is GIS’s just … • My contention is that it also has to address the following: - Technological, - Human, - Material, - Administrative and - Financial issues • To be functionally successful.
LITERATURE EXPLANATIONS • According to Rhind (1989) a GIS is a computer system that can hold and use data describing places on the earth’s surface. • ... in GIS the common purpose is decision making for managing the us of land, resources, transportation, retailing, oceans or any spatially distributed entities (NCGIA, 1989).

GIS is built on knowledge of various academic disciplines • That includes: • Geography • Cartography • Location Science • Computer Science • Data Modelling • Database Design • Computer Graphics • Interface Design • Mathematics • Topology • Graph Theory • Geometry • Statistics • Traditional Statistics • Spatial Statistics • Information Science • Storage & Retrieval Methods • Metadata Documentation • Integrated into a GIS
Some GIS Application Arear’s • Agriculture • Forestry & Wildlife Management • National, State, County, Regional, Local mapping and geographic inventory • Archaeology • Geology • Oil and gas exploration and production • Municipal Applications • Streets • Properties/Cadastre • Facilities • Utilities • Water, Sewer, Storm Sewer • Environment • Areas/Districts • Utility Applications • Electric • Gas • Telephone • Cable Television
Data integration: The linking of information in different forms through a GIS.
RESEARCH AIMS • To examine the necessary infrastructural requisites at a Tertiary Institution in Africa.
OBJECTIVES 1)To examine the technological, human, financial and administrative resources required to put in place a functional GIS teaching program at a tertiary institution; 2) To highlight the core GIS Curriculum & its necessary pre-requisites for teaching GIS at a tertiary institution in Africa using The University of Limpopo, S. Africa as a Case study.
KEY INFRASTRUCTURAL ISSUES The main infrastructural issues are 1 Function & / or Purpose, 2 Technological Resources, 3 Human Resources, 4 Financial & Administrative Resources, and 5 Future Proofing.
FUNCTION &/or PURPOSE OF A GIS TRAINING FACILITY • In designing & developing the support infrastructure, clear recognition of the intended purpose and desired outcomes is critical for successful implementation of a GIS graduate and/or postgraduate program. • There is no single model that can be employed by all in the development of an infrastructure to support GIS education. • There are a variety of scales of implementation, teaching styles, learning priorities, and institutional frameworks within which instructional takes place. • The function may vary from a strictly educational role to a combination of research &/or contract work and education.

DESIGN & MAINTENANCE Locational Info via a RDMS • Here one needs to ask the question: • Is the facility to be a stand alone or a network GIS facility • Stand alone cost vs network costs &/or savings & requirements COME INTO THE BASKET OF COSTS • Such considerations are fundamental to the determination of hardware, software, data and personnel needs to operationalize a functional GIS FACILITY. Data via a GIS
MATERIALS Electronic Class Room for GIS Teaching • Beyond the physical facilities instructional materials must be procured; • The WWW has access to software, data, exercises & curricular materials; • Where facilities are limited, internships & cooperative work with local agencies (Govt. & Public/Private Companies may augment resources & provide more broad reaching benefits.

SAFETY & SECURITY Operating system security functions, virus checkers & network controlled programs offer protection on the software side but only if installed & maintained correctly; Policies for access and backup are necessary complements to physical security measures. HUMAN RESOURCES FacilityAdmin SAFETY & SECURITY & HUMAN RESOURCES • Management issues are vital to the successful operation of the GIS infrastructure. • Staffing • Personnel is generally the last budget item considered. • The type of support (full or part-time, shared or not) & the expertise level of the individuals would determine how well the facility meets the user’s needs. • Alternative strategies: G/Asst, UL Computing services & Faculty may be the mix.
FINANCIAL RESOURCES • Funding • Given the growing & tightening funds all sources should be explored. • Internal funding may be available in the form of grants, laboratory fees or capital expenditure funds. • External mechanisms include grants, contracts and donations. Explore this through contract & CBO/NGO GIS work.

CHALLENGES IN AFRICA!Can a GIS Help? • There are major challenges in the world today, viz: • overpopulation; • pollution; • deforestation; • natural disasters; • water shortages • All have a critical Geographical Dimension and can use a GIS to help manage the dynamic challenges.

BENEFITS & IMPORTANCE TO AFRICA’S NEEDS • While the issues outlined in the paper focussed on the specifics of infrastructure establishments & management the overall effort is directed towards the removal of physical impediments to instruction in a largely technological development field – GIS Training & Education in Africa for Africans. • The CACGIS Laboratory at UL can, in part, play a leadership role in assisting with GIS Infrastructural Requisites for Africa.
Concluding Remarks & Recommendations • With the continual changes occurring in GIS support infrastructure, it is difficult for any one individual or department to keep up with the state-of-the-art in the GIS Fields. • It is undesirable for time and resources to be unnecessarily diverted from conceptual and instructional development to management and maintenance. • Yet is vital that the practical component of GIS instruction remain up to date. • As a starting point a guide which sets out the basic steps as well as scenarios for development and/or management of GIS facilities under different resource conditions would be helpful.
