Digital Geologic Map

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 maps of National Park areas visit the Geologic Resources Inventory Publications page on this site.

Geologic Map

Geologic Maps

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 at

Topographic Map

Topographic Maps

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 .

General Map

General Park Maps

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.
