Design And Implementation Of A Computer Based Cartographic System

BACKGROUND OF THY STUDY
1.1 INTRODUCTION
Cartography is study and paractice of making maps or globes. Maps have traditionally been made using pen and paper, but the advent and spread of computers has revolutionized cartography.
Most commercial qualities maps are now made with map making software that falls into one of the three main types, CAD, GIS AND specialized map illustration software.
Maps functions as visualization tolls for spatial data. Spatial data is acquired from measurement and can be stored in a database from which it can be extracted from a variety of purposes. Current trends in this field are moving away from analog methods of map making and towards the creation of increasingly dynamic, interactive maps that can be manipulated digitally.
The cartographic process rest on the premise that the world is measurable and that we can make reliable representations or models of that reality. Map making involve advanced skills and attitudes, particularly the use of symbols to represent certain geographic phenomens, as well as the ability to visualize the world. In an abstract and scaled down form.

1.2 STATEMENT OF THE PROBLEM
The present system of cartographic system of Nigerian population commission has a lot of problems, which are mentioned below.
ACCURACY
In term of accuracy, the system is relatively slow and since it is dependent to human effort, so inevitable, it is also prone to human errors and omission.
TIME
Going by the present system of operaion, time is consumed in the handling of operation; since most cartographic drawings are manilly operated with pen and papers. It takes time to execute a particular work.

1.3 PURPOSE OF THE STUDY
The objectives of the study is designed to help the Nigeria population commission in their cartographic and maps designing and rpresentation.

1.4 OBJECTIVES OF THE STUDY
The objectives of the study are as follows
1. To provide better efficient job presentation for various designing in the commission.
2. To produce a system where information and output report will be produced much faster, more accurately and more detailed to the commission.
3. To keep records that are compact, integrated and updated.

1.5 SCOPE OF THE STUDY.
This study is strinced at finding out how effectively the computerization of the commission cartographic system will improve the operation of the commission. However, the project is narrowed to planning department that is responsible for map presentation and enumeration demarcation.

1.6 LIMITATION
The following constrants were faced by the research and limited the effort in the developing of a comprehensive package needed in the commission.
1. TIME: This project work has one semester time limit. It would have been desirable for a longer period of time for the development of a package for the commission.
2. INFORMATION: For some security reason, access to some vital information were deprived by the commission.

1.7 ASSUMPTION
Due to insufficient information, I assumed the following;
(a) The staff of the particular department should be computer literate.
(b) There should be enough tools and equipment for the operations.

1.8 DEFINITION OF TERMS
Computer:- A computer system is an electronic device with certain physical and logical attributes which enables it to accept input, process input and brings out output.
PROGRAMMING: Programming is a term used to refer to the act of formulating algorithms and data structure which can be executed by some computers, to perhaps yield the required solution to a given problem.
FLOW CHART: A flow chart represents a systematic way of carrying out a process and is of use when writing a computer program.
