TOPOGRAPHIC MAPS: The basics. 2. Topo tip: • Use contour lines to determine elevations of mountains and flat areas. The closer together the lines are, the steeper the slope. • Contour elevation numbers indicate the direction of elevation by always reading (pointing) uphill. What is scale? Maps are made to scale. In each case, the scale . represents the ratio of a distance on the map to

Chapter 2 Reading Topographic Maps and Making Calculations

Interpreting Contour Lines Contour lines on a map show topography or changes in elevation. They reveal the location of slopes, depressions, ridges, cliffs, height of mountains and hills, and other topographical features. A contour line is a brown line on a map that connects all points of the same elevation. They tend to parallel each other, each approximately the shape of the one above it and

1 ABSTRACT This experiment is to determine the capacity of oil reservoir if map showing contour lines (isopach) for the area of the reservoir is available. This experiment is carried out using planimeter. Firstly, the planimeter was switched on and one set of contour was chosen to be measured. Secondly, a mark was made on the contour map as a starting point of measurement.

Topographic map - Wikipedia

Topography concerns the shape and character of the Earth's surface, and maps were among the first artifacts to record these observations. In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines (connecting points of equal elevation), but historically using a variety of

How to Read a Topographical Map

Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map. If you look at the areas marked with an orange box on this map you will see contour elevation numbers. This is the elevation of the contour line, relative to mean sea level.
