Electronic Mapping System - Chapter1
Chapter I
INTRODUCTION
A century ago almost all maps were printed on paper. With advances in technologies we now find maps in any other formats. Mapping activities are on the rise as more and more data become available and computer software takes over the tasks of processing the data. The methods used for creating maps have changed dramatically during the past ten years. The map production process consists of several discreet components from an initial design concept through the completion of the map in its final form.
The functionality of maps has been greatly advanced by technology. In electronic maps having local information within the map allows more efficient analysis and better decision making. Usually traditional maps are used for general reference but in our digital world many local and regional governments maintain databases for the storage of information. In this environment maps are generated as they are needed because the database is updated constantly.
Information System (IS) is a part of the development of electronic mapping nowadays. IS are set of components for collecting, storing, and processing data and for delivering information, knowledge, and digital products. Hence, mapping system is said to be classified as a Geographical Information System (GIS).
A Geographic Information System, or GIS, is an organized collection of computer hardware, software, geographic data and functionality, accessed by the GIS user capture, store, update, manipulate, analyze, and display all forms of geographically referenced information. GIS allows us to view, understand,
question, interpret, and visualize data in many ways that reveal patterns and trends in the form of maps.
Making decisions based on geography is basic to human thinking. Where we shall go, what will it be like, and what shall we do when we get there are applied to the simple event. By understanding geography and people’s relationship to location, we can make informed
