Divide students into teams. Ask each team of students to determine the latitude and longitude of the school building or campus to the nearest second using a USGS 1:24,000-scale topographic map. Draw a 2.5-minute grid on the interior of the map using 2.5-minute tic marks on the margin of the map as a guide for interpolating the coordinates.

Topographic Mapping and the USGS. A longstanding goal of the USGS has been to provide complete, large-scale topographic map coverage of the United States. The result is a series of more than 54,000 maps that cover in detail the entire area of the 48 contiguous States and Hawaii. Produced at a scale of 1:24,000 (some metric maps are produced at ...

This is accomplished by selecting a map scale that is neither too large nor too small and by enhancing the map details through the use of symbols and colors. The most common USGS topographic map scale is 1:24,000. In this scale 1 inch on the map represents 24,000 in, or 2,000 ft. (1 cm represents 240 m) on the ground.

Suggestions for teaching this lesson (2, 30-minute sessions) As your students have learned, there are many different kinds of maps. This lesson focuses on three basic types of maps—aroad map, a shaded relief map, and a topographic map. 1. Pass out Activity Sheet #3. Ask stu-dents to take out their map packets.
