1.1 What is GIS?

A Geographic Information System (GIS for short) is a system that allows users to create digital maps, store and maintain spatial data (such as a parcels database) and solve geographical problems. The tutorial below explains how GIS users turn data into information and how a GIS models our world with points, lines, polygons and rasters. This tutorial also highlights the different components of a GIS System (Hardware, Software, Procedures, Networks, Data and People) and gives a brief overview of who is using GIS and lists tasks that are commonly accomplished with GIS.
