A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations 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.

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.


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.


Spatial analysis lets you evaluate suitability and capability, estimate and predict, interpret and understand, and much more, lending new perspectives to your insight and decision-making.


Apps provide focused user experiences for getting work done and bringing GIS to life for everyone. GIS apps work virtually everywhere: on your mobile phones, tablets, in web browsers, and on desktops.


Hundreds of thousands of organizations 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

Use GIS to illuminate issues that are driven by geography. A map of opioid prescription claims can reveal the geographic patterns that emerge when data is well-mapped.


Manage & Respond to Events

GIS delivers real-time situational awareness. A hurricane and cyclone map can show the potential impact to people and businesses, probable track of storms, and storm surge.

Set Priorities

GIS helps to set priorities based on spatial analysis. By analyzing crime patterns, public safety officials can identify target areas and assign officers in those areas.

Monitor Change

If a picture tells a thousand words, a map tells a thousand pictures. A map can reveal the extent of glacier retreat in the Southern Hemisphere.

Perform Forecasting

Use GIS to forecast traffic. A map can highlight challenges at an intersection in Fort Mitchell, Kentucky, where forecasting shows traffic is expected to worsen based on land use changes.


Understand Trends

GIS helps you gain insight into data that might be missed in a spreadsheet. A map can measure job growth or losses in different industries and quantifies local competitive advantage.
