What is GIS
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. This map of opioid prescription claims reveals the geographic patterns that emerge when data is well-mapped.
Monitor change
If a picture tells a thousand words, a map tells a thousand pictures. This map starkly reveals the extent of glacier retreat in the Southern Hemisphere.
Manage & respond to events
GIS delivers real-time situational awareness. This hurricane and cyclone map shows potential impact to people and businesses, probable track of storms, and storm surge.
Perform forecasting
Use GIS to forecast traffic. This map highlights challenges at an intersection in Fort Mitchell, Kentucky, where forecasting shows traffic is expected to worsen based on land use changes.
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.
Understand trends
GIS helps you gain insight into data that might be missed in a spreadsheet. This map measures job growth or losses in different industries and quantifies local competitive advantage.
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.
