    A Geographical Information Retrieval System

    CHAPTER ONE

    Introduction

    1.1 Background Of Study

    According to Chang, K. T. (2008), Geographic Information Retrieval System (GIRS) is a system designed to capture, store, manipulate, analyze, manage and present all types of geographical data. The acronym GIRS is sometimes used for geographical information science or geospatial information a study which refers to the academic discipline or career of working with geographic information system. In simplest terms GIRS is the merging of cartography, statistical analysis and database technology.

    A geographical information retrieval system can be thought of as a system which digitally creates and manipulates spatial areas that may be jurisdictional, purpose or application- oriented. Generally, a GIRS can be custom designed for an organization. Hence, a GIS developed for an application jurisdiction, enterprise or purpose may not be necessarily interoperable or compatible with a GIRS that has been developed for some other application, jurisdiction, enterprise or purpose. What goes beyond a GIRS is a spatial infrastructure, a concept that has no such restrictive boundaries.

    In general sense, the term GIRS describes any information system that integrates, stores, edits, analyzes, shares and displays geographic information for informed decision making. GIRS applications are tools that allow users to create interactive queries (user − created searches), analyze spatial information, edit data in maps and present the result of all these operations. Geographic information science is the science underlying geographic concepts, applications and systems.

    The link between geography and information technology can not to a very large extent be over- emphasized.

    Using Enugu State tourism board as a case study has helped to give a comprehensive understanding of the importance and the need of a geographic information system, as it is believed, information technology has a significant role in geographic information system and high level of expectations would and is already being demanded from its use both in Nigeria and the world at large.

    1.2 Statement Of The Problem

    In our daily lives as humans, most of our endeavors involve moving from one location to another for one thing or the other. A problem emerges when there is no proper direction or a system as to give accurate direction in locating our destination, what the said destination contains and what is has to offer. This is the problem the state has as concerning tourism, whereby a good number of tourists

    (most especially tourists visiting for the very first time) and other individuals wanting to visit tourist sites in the state but cannot do so because of the lack of a well detailed system to provide them (tourists) with an accurate geographic information system as to how to locate these sites within the state.

    Due to the lack of an accurate geographic information retrieval system as far as tourism is concerned, most tourists are discouraged from exploring these tourist locations within the state, this in turn hampers the positive impact that tourism is meant to have on the development in the state and the Nigerian society at large.

    1.3 Objectives Of The Study

    1. To examine the existing / current system in regards to how geographic information for tourism is provided for tourists in and outside the state.
    2. To improve on the already existing system by designing a geographic information retrieval system that is well detailed and easily accessible.
    3. This study also seeks to help in broadening the scope of tourism in the state through providing a comprehensive geographic information retrieval system.

    1.4 Significance Of The Study

    The significance of this study is to show that a link between geography and other professions can be created on the platform of information technology. i.e. to show that with information technology the problem of location can and is solved to a very large extent.

    Defense Procedure for Computer Science Researchers

    In preparation for defending a project or seminar on A Geographical Information Retrieval System, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

    Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

    Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

    During the question and answer segment, the External Examiner may pose questions pertaining to your research. If confronted with a challenging or irrelevant question, respond diplomatically with, “Sorry, Sir/Madam, the question asked is beyond the scope of my study.” Whenever possible, direct your answers back to your research findings to reinforce your expertise.
