Topographic Maps

Background:

Topographic maps are maps that show locations and elevations of natural and cultural features of a given area.
Standard colors and symbols have been designated for use on these maps by the United States Geological Survey.
Topographic maps are generally oriented to show north at the top. Scales and contour intervals vary on topographic maps
depending on the series of the map and the relief (the variation in elevation) of the topography.
Using the Internet students can create topographic maps for any area in the United States.  Students need to input the latitude and longitude or the zip code to create a map of their choice.

Purpose:

Learn the standard symbol signs and colors used on a topographic map. Become familiar with directions, scales,
elevation readings, and ways of locating various features on topographic maps.
