GIS - Mapping

A Geographic Information System (GIS) is an organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information.

One of the most powerful features of geographic analysis is the ability to compare different layers of information. Just as a County agency may store information in different databases, GIS stores information in thematic layers. Chelan County data can be divided into layers such as streets, hydrology, parcels, etc. Each layer is managed separately in a GIS.

A GIS can provide a unique insight into many difficult problems. The benefit of a GIS is that it provides a graphical representation and an intelligent database about the inventory of geographic elements. This inherent ability of GIS to locate features spatially adds a great deal of power and flexibility to a database.
