A geographic information system (GIS) is a framework for gathering, managing and analysing data. Rooted in the science of geography, GIS integrates many types of data. It analyses spatial location and organises layers of information into visualisations using maps and 3D scenes. ​With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships and situations - helping users make smarter decisions. 

What is GIS?

Hundreds of thousands of organisations in virtually every field are using GIS to make maps that communicate, perform analysis, share information and solve complex problems around the world. This is changing the way the world works.
