What is GIS

What is GIS

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.

What is GIS

• Geographic – physical features of earth and how it affects human activity, including population and resources, land use, and industries.

• Information – computer technology, hardware, software, internet, networking, telecommunications.

• System(s) – data collection, storage, processing, creation, and distribution.

What is GIS

A GIS combines individual layers of data such as customers, buildings, and streets to model the real world.

Uses of GIS

Uses of GIS

Map where things are.

Mapping where things are lets you find places that have the features you’re looking for, and see where to take action. You can also begin to understand why things are where they are.

Uses of GIS

Map quantities.

Mapping the most and the least lets you compare places based on quantities so you can see which places meet your criteria, or understand the relationships between places.

Uses of GIS

Map densities

Mapping the density of features lets you see the patterns of where things are concentrated. This helps you find areas that require action or meet your criteria, or monitor changing conditions.

Uses of GIS

Find what’s inside.

Finding what’s inside lets you see whether an activity occurs inside an area, or summarize information for each of several areas so you can compare them.

Uses of GIS

Find what’s nearby.

Finding what’s nearby lets you see what’s within a set distance or travel range of a feature. This lets you monitor events in an area, or find the area served by a facility of the features affected by an activity.

Uses of GIS

Map change.

GIS lets you map where things move, or the changing conditions in a place over time. Knowing what’s changed can help you understand how things behave over time, anticipate future conditions, or evaluate the results of a an action or policy.
