Geographic Information Systems (GIS)

What is a Geographic Information System (GIS) and what do we use it for? This question may be hard to define as there are infinite uses for a GIS. A GIS is a system that holds, displays and manages multiple layers of geographical information. A GIS can be used to collect and analyse data in many ways, allowing patterns in the data to emerge and then present it in the form of maps, charts and/or reports.

A GIS is a very useful tool for anyone in the planning profession and can be used to solve problems by reviewing data in a way that is quickly understood and easily shared. A GIS can hold multiple layers of information and is customisable to any entity that has the need to maintain geographical data. No GIS that exists today has reached its full potential as a GIS has the capacity to cater for a one-stop-shop of infinite information.

With technological advancement moving at an increasing rate, Governmental department should realise the potential of GIS and embrace it, offering one central system that can be easily accessed by the public. This system could store and display relevant data from each Government department, creating a sense of unity throughout the Government and an excellent source of information for the whole of society. This would also benefit the public sector as it would alleviate pressure on public relations.  This is good in theory, however this poses many questions. How long would this take to execute...or...is it possible? Would our Government ever take this unified approach?
