Digital Geologic Data
Digital geologic data allows natural resource managers and staff to more easily evaluate potential connections between geology and other ecosystem components. Such data is also more easily incorporated into planning when it is available digitally through geographic information systems (GIS.)
To find digital geologic map datasets for National Park areas visit the Geologic Resources Inventory page on this site. An image of the map is available for viewing or printing as a Park Geologic Map Poster using the links below:
Posters are a static view of the GIS data in PDF format. Newer posters include aerial imagery or shaded relief and other park information. They are also included with the Geologic Resources Inventory Reports.

Geologists make and use special maps that show and identify the rocks at and beneath the surface of the earth. These geologic maps are important for deciding where to build trails and buildings and for a wide range of natural resource management applications. Digital geologic maps in conjunction with other spatial data can be useful for problem solving in geographic information systems. To find published geologic maps, data, and related products from 300+ publishers search the USGS National Geologic Map Database.
Topographic maps use contour lines to depict elevation in addition to most of the things shown on general maps. These maps are true to scale and can be used to calculate distance, slope, and position. Topographic maps are essential to off road navigating and are often used by back country explorers. To find topographic maps visit the USGS Science Explorer.
Most people are familiar with this type of map, these maps usually show roads, towns and cities, rivers and lakes, campgrounds and visitors centers, as well as State and local boundaries. Whenever you visit a National Park you receive a general map of that park in the park brochure.
