GIS and mapping
Mapping is an essential function of a GIS. People in a variety of professions are using GIS to help others understand geographic data. You don't have to be a skilled cartographer to make maps with a GIS. Look at the examples below and see some of the ways people are making maps with GIS.

You can use GIS to



Create Detailed Regional Road Maps

Using a GIS you can create maps that show roads, lakes, rivers, cities, and towns.

The Bluegrass Area Development District uses GIS to create their official Vacation Guide Kentucky Highway map.

Because the map is created from data in the GIS, any changes in the GIS database will be reflected in the next printing of the map, allowing the District to make changes to the map with minimal effort and cost.

H.M. Gousha Company uses GIS to create detailed road maps for the entire United States.

This example shows the roads for the area surrounding Atlanta, Georgia.

Using existing digital data and scanned images, technicians created a database for the entire State that can be easily maintained and altered for future printings.

Create City Street Maps

METRO DRC of Portland, Oregon, uses a GIS database to create their City street maps. This example is a map showing the City streets and suitable bike routes within the City.

This map also shows recreational trails and classifies them according to bicycling suitability.

Create Shaded Relief Maps

The physical characteristics of Maine's differing elevations can be instantly appreciated by using the GIS database to create color-shaded relief maps.

The Maine Office of Geographic Information Systems uses the GIS to show how elevation (shown in shaded relief and by color) affects the distribution of Maine's 15 "natural areas" and their associated species.

The Bureau of Land Management uses GIS to create maps that show an ecosystem (in this example the Columbia River Basin).

Using the GIS they can create maps that show the entire system with its relief in exceptional detail.

Create 3-Dimensional Maps

The U.S. Geological Survey uses GIS to map geology 3-dimensionally. This example uses a series of plots to show the Quarternary deposits for an area in east-central Illinois.

Displaying the data 3-dimensionally enhances the visualization by the reader and gives a more realistic interpretation of the deposit distribution.
