Basic Map Reading 1 and 2: Slide/Tape Programs

摘要

The Basic Map Reading program is a narrated visual treatment of skills necessary to use and understand topographic maps properly. The program emphasizes standard USGS 15' quadrangle maps since they are the most commonly used maps in this country. But the basic skills explained in the program are useful when using any topographic map. The program is divided into Part I and Part II to make the segments short enough for comfortable viewing and listening without fatigue and to provide a natural break in the content of the material presented. Part I deals with the quantitative aspects of a topographic map and the important features of a USGS 15' quadrangle map sheet. The program shows how distance, elevation, direction, area, and position are determined from a topographic map. Part II treats the qualitative aspects of a topographic map. Interpretation skills necessary to understand symbology and identify landforms using contour lines are covered in this segment.
