GIS (Geographic Information System) 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.

Data management - GIS is a foundational system of records. 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.
