Constructing a topographic map by drawing in contours can be easily done if a person remembers the following rules regarding contour lines: As you draw a contour line on a map you will notice that the elevations on one side of your line will be lower elevations, and elevations on the other side of your line will be higher elevations. A contour interval is a vertical distance or a difference in elevation between contour lines in a topographic map, index contour lines are bold or thick lines that appear on every fifth contour line and if the number associated with specific contour lines is increasing, the elevation of the area is also increasing.

For small scale maps covering a wide area of varying terrain, For rough topographical map meant for initial assessment only, If a detailed map is to be prepared for execution work, If the ground has large variation in levels, for instance, hills and ponds, No measurement or scaling is required since the contour levels are indicated on the contour lines, The distance must be measured on the map and converted to actual distance by multiplying with the scale of the map, In a given map the contour interval is a constant, The horizontal equivalent varies with slope. 16. Lets assume, 7000 and 7100 and calculate the interval between it. 40 feet - 20 feet = 20 feet Based on the drainage pattern type, does the bedrock underlying this area consist of rocks uniformly resistant to erosion or rocks alternating between resistant and non-resistant layers? the entire earth to a city block (or less).
