Map Scales
Map scale is a very important feature on a Topographic Map, it is the ratio between the distance on the map and the corresponding distance on the ground.

What Cannot be shown on a topographic map?

What are topographic symbols?
A topographic map shows more than contours. The map includes symbols that represent such fea- tures as streets, buildings, streams, and vegetation . These symbols are con- stantly refined to better relate to the features they represent, improve the appearance or readability of the map, or reduce production cost.
