What Is GIS?
A Geographic Information System is an automated system that provides for the capture, storage, display, manipulation, and output of spatially referenced data.
In a GIS model:
- Data is organized by layers
- Each layer represents a common feature (transportation, soils, elevation…)
- Layers are bound by a common reference system
For a general overview of GIS and how it is applied in different industries check out ESRI’s About GIS.
ESRI and the office of the CIO have partnered to provide software and instruction to all K-12 schools in Nebraska. To take advantage of GIS in your class, visit: needgisimaps.arcgis.com or www.cionebraska.gov/gio/services.html
