A Computer-Based Cartographic System (CBCS) is a sophisticated geospatial technology that harnesses the power of computers to create, analyze, and present maps with precision and efficiency. This advanced system utilizes digital data and algorithms to generate cartographic representations, incorporating geographical information seamlessly. It plays a pivotal role in diverse fields such as urban planning, environmental management, and navigation. The integration of cutting-edge technologies enables a dynamic and versatile approach to cartography, allowing users to manipulate and visualize spatial data with ease. By leveraging keywords such as “computer-based,” “cartographic system,” and “geographical information,” the Computer-Based Cartographic System emerges as an indispensable tool for spatial analysis and decision-making across various domains, contributing to the evolution of modern mapping practices.

ABSTRACT

This project carries out a study need for the design and implementation of a computer based cartographic system using National population commission as case study.
The researcher attempt to find out an improved method of cartographic drawing and how to automate the process (computerization).
Hindrances encountered in the mammal process that is, old approach of using and papers in drawing maps which could lead to poor representation of graphs, maps, hence the need for a well design and implemented computer based cartographic system arises.
This project computer based cartographic system will also help to keep record of many areas and maps of this country.

CHAPTER ONE

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.

Computer Based Cartographic System:

A Computer-Based Cartographic System (CBCS) is a system that utilizes computer technology to create, manipulate, store, analyze, and display maps and geographical data. This type of system is commonly used in various fields, including geography, geology, urban planning, environmental science, and many others where spatial information is essential. Here are the key components and functions of a Computer-Based Cartographic System:

Data Input: Computer-Based Cartographic System starts with the collection and input of geographic data. This data can come from various sources, including GPS devices, remote sensing technologies, surveys, and existing databases. It is essential to ensure data accuracy and consistency.

Data Storage: Geographic data is stored in digital format within the Computer-Based Cartographic System. Databases or Geographic Information Systems (GIS) software are often used to manage and organize this data efficiently. Geographic data can include information like coordinates, elevation, land use, and more.

Data Manipulation and Analysis: Computer-Based Cartographic System allows users to perform various operations on the geographic data. This includes spatial analysis, such as overlaying maps, calculating distances, identifying patterns, and conducting queries to extract specific information.

Map Design and Visualization: One of the primary purposes of a CBCS is to create maps. Users can design and customize maps based on their specific needs. They can choose symbols, colors, labels, and scales to represent geographic features effectively.

Geocoding: Geocoding is the process of converting addresses or place names into geographic coordinates (latitude and longitude) on a map. Computer-Based Cartographic System can perform geocoding to display locations accurately.

Routing and Navigation: Some Computer-Based Cartographic System can provide routing and navigation features, allowing users to find the best routes between locations, estimate travel times, and even incorporate real-time traffic data.

Data Sharing: Computer-Based Cartographic System enables users to share maps and geographic data with others easily. This can be done through various means, such as exporting maps as image files, sharing interactive maps online, or providing data in standard formats like shapefiles or GeoJSON.

Spatial Analysis: Computer-Based Cartographic System can perform advanced spatial analysis, such as spatial statistics, spatial modeling, and suitability analysis. These tools help in decision-making processes related to land use planning, environmental management, and resource allocation.

Data Visualization: Modern Computer-Based Cartographic System often include tools for 3D visualization, allowing users to represent geographic data in three dimensions, which can be useful for urban planning, terrain modeling, and simulations.

Integration with External Data: Computer-Based Cartographic System can integrate with other data sources, such as weather data, demographic data, and socio-economic data, to provide a comprehensive view of the geographical context.

User-Friendly Interfaces: To make Computer-Based Cartographic System accessible to a wide range of users, it typically includes user-friendly interfaces and tools for creating maps and conducting analyses without requiring extensive technical expertise.

Overall, a Computer-Based Cartographic System plays a vital role in understanding, managing, and making decisions related to geographic and spatial information. It helps professionals across various disciplines leverage the power of digital technology to address complex spatial challenges.
