Geographic Information Systems

Contents

Introduction

Geographic information systems (GIS) are computer-based systems used to store, display, and analyze geographically referenced data, i.e., data identified according to their locations. GIS are also defined as computer-based mapping and information systems that enable the user to analyze geographic data in a variety of ways. GIS have a wide variety of applications for public works, planning and permitting, public safety, and other local government activities.
