Geographical Information Systems (GIS) is a relatively new, albeit fast growing area of IT. Even 15 years ago there were no maps really stored on computers and it is only since the advent of mobile phones, GPS and satellite tracking that this aspect has become so crucial.

In short, GIS is a computerised system that stores mapping data and uses the information to plot coordinates and find locations or assets. Assets could include transport or telecommunications networks, buildings, and so on. The amount of data required to construct a map, let alone pin point a location, is immense and GIS officers are in charge of this. They can work in a number of areas, including commerce and retail, government and defence, transport and logistics.

GIS Officers initially begin by collating and digitising data, either from hard, paper maps or older computerised programmes. This will then be updated and transferred into a modern format which can be used on modern computer systems. All maps are then plotted and checked before being uploaded into appropriate, user-friendly formats for the end user.
