What is GIS?

A framework to organise, communicate and understand the science of our world

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.

Identify problems Monitor change Manage & respond to events Perform forecasting Set priorities Understand trends

How GIS works

GIS technology applies geographic science with tools for understanding and collaboration. It helps people reach a common goal: to gain actionable intelligence from all types of data.

    Maps

    Maps are the geographic container for the data layers and analytics you want to work with. GIS maps are easily shared and embedded in apps and accessible by virtually everyone, everywhere.

    Data

    GIS integrates many different kinds of data layers using spatial location. Most data has a geographic component. GIS data includes imagery, features and basemaps linked to spreadsheets and tables.
