Introduction Introduction 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 ?
