WHAT IS GIS? Geographic Information System (GIS)

The mapping and data analysis technology that’s powering business decisions, supporting government operations, and quietly changing the world.

To make sense of the immense amount of data in today's world, we can map it. When we visualize and analyze data on a map, hidden connections and insights emerge. GIS gives us a deeper understanding of our world, guiding decisions and actions.

GIS is a unique problem-solving technology with remarkable impact. Play the video to learn from visionary leaders and technology professionals as they describe in their own words what GIS is, how it works, and why it matters.

FORMAL DEFINITION

Geographic information system(s), GIS (noun)

GIS is a technology that is used to create, manage, analyze, and map all types of data.

GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication, efficiency, management, and decision-making.

What does GIS do?

While mapping is fundamental, GIS does much more.

Data management

GIS is a foundational system of record. You can store and integrate information from business systems and authoritative sources, magnifying data’s usefulness.

Mapping and visualization

From digital maps and dashboards to satellite imagery, 3D, and real time—GIS brings data to life, helping us understand problems and solve them.

Spatial analysis

Most data has a location component—everything happens somewhere. With spatial analysis tools, we find hidden relationships and generate new insights from data.

Communication

Maps and dashboards communicate complex ideas quickly. Science and data build common understanding, supporting collaboration and problem-solving.
