Geographic Information Systems (GIS) is the convergence of software, hardware, and data to create, analyze, manage, and display geographic information. GIS enables us to visualize data, understand patterns and relationships, and interpret trends.
Maps enable an immediate understanding of the patterns and relationships the information portrays. -Esri President Jack Dangermond
Where? Many of todays problems are geographic and require spatial problem-solving. Every day, millions of decisions are powered by GIS. Siting a new store, modeling groundwater, deploying emergency responders, hazard planning.
A GIS connects data with geography. Mapping your data allows you to fully understand the spatial relationships between elements of your project area.
