A Geographic Information System (GIS) is a computer system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to Earth. GIS allows users to create interactive queries, analyze spatial information, edit data in maps, and present the results of all these operations. The document outlines the key components of a GIS including computer hardware, software modules, and databases for organizing spatial data. It also discusses different methods for inputting existing data, maps, and field observations into a digital GIS format.

IntroductionIntroduction
 A Geographic Information System (GIS) is an
information system that is designed to work with
data referenced by spatial or geographic
coordinates. In other words, a GIS is both a
database system with specific capabilities for
spatially referenced data, as well a set of
operations for working with data. In a sense, a
GIS may be thought of higher order map.
 What is difference between DATA &
Information ?
 Any relevant background and interest of the
audience ?
