1.5 SCOPE OF STUDY
The scope of this study is limited to tourist locations and hotels within the state using the Enugu state tourism board as a case study in view of providing / improving on the existing geographic information system of the board for tourism in the state.
1.6 LIMITATIONS OF THE STUDY
Time was a major constraint faced during the research for this project work and limited the effort in developing a much more comprehensive package needed in the design and implementation of the geographic information retrieval system.
1.7 DEFINITION OF TERMS
GEOGRAPHY: Geography is a science that deals with the distribution and arrangement of all elements of the earth‟s surface. The word geography was adopted in the 200s BC by the Greek Scholar Eratosthenes and means „earth description.‟

SOFTWARE: This is the logically written instruction that controls the operations of the hardware.
HARDWARE: This is the physical components of computer system and other geographic tools or devices.
DATABASE: This is the collection of related data/ information stored mostly in a central location.
COMPUTER AIDED DESIGN (CAD): Software programs for the design, drafting and presentation of graphics. Originally designed for manufacturing and drawing, now also widely used for mapping.
OPERATING SYTEM: A series of computer programs which control the operations of the computer itself. Application programs such as GIS software run under an operating system. Examples of operating system include UNIX, VMS, DOS etc.
